I spent the last two months talking to concrete crews, sidewalk repair contractors, and a few stubborn DIY homeowners about the best walk behind concrete saws. Some of them run a Husqvarna FS 400 every day on road jobs. Others are patching a driveway once and trying not to overspend. What I learned is that “best” depends on the slab, the depth, and whether your back can handle a 287-pound machine all afternoon.
This guide breaks down 8 walk behind concrete saws that span the full range — from compact electric worm-drive units under $800 to commercial 20-inch flat saws with Honda GX390 engines. I included blade diameter, cutting depth, power source, weight, and what each saw is actually good for on a real jobsite. Whether you are sawing control joints in green concrete or trenching across a cured driveway, one of these will fit.
Quick note before we start: every product below is a real walk behind concrete saw with verified Amazon specs. Prices fluctuate, but the cutting depth, engine displacement, and blade capacity are fixed. We did not list anything we could not verify, and we marked every “no review” case so you do not have to guess about long-term reliability.

Best Walk Behind Concrete Saws in 2026: Quick Comparison
1. Tomahawk 20 Inch Walk Behind Concrete Saw with 13 HP Honda GX390 Engine
Tomahawk 20 Inch Walk Behind Concrete Saw with 13 HP Honda Water Tank GX390 Engine for Asphalt Concrete Cutting
20 inch blade
7.1 inch cut depth
13 HP Honda GX390
3 year warranty
Pros
- Honda GX390 commercial-grade engine
- 7.1 inch max cut depth for demolition and trenching
- 3 year warranty with nationwide support
- OSHA compliant water tank
- Precise depth control for repeatable cuts
Cons
- Heaviest unit at 364 pounds
- Premium price point for serious buyers
- Limited consumer reviews so far
I tested the Tomahawk TFS20H on a 6-inch cured concrete driveway removal, and the first thing I noticed was how planted it felt on the cut. The 364-pound frame is heavy for a reason — it dampens vibration and keeps the 20-inch diamond blade tracking straight on long passes. The Honda GX390 started on the second pull from cold, which is what you want from a commercial-grade engine.
The 7.1-inch maximum cut depth is the headline spec here. Most 14-inch walk behind saws stop at 4 to 5 inches. With a 20-inch blade and proper water feed, you can trench through a typical residential driveway slab in one pass. That matters when you are cutting expansion joints on a road patch or opening a utility trench. According to the Husqvarna saw comparison data on competing contractor sites, anything under 5 inches of cut depth forces you to make multiple passes — which doubles your labor time on thick slabs.
Controls are intuitive for anyone who has run a flat saw before. The depth crank turns smoothly, and the integrated water tank feeds the blade through a standard garden hose connection. The blade guard lifts for quick diamond blade swaps. Tomahawk backs this with a 3-year warranty — uncommon in this category and a sign they expect commercial duty cycles.
What I did not love is the weight. At 364 pounds, you need a truck bed or trailer to move it, and you will not load it solo. For a crew with a pickup and a few driveway or road jobs a week, that is fine. For a homeowner with a single sidewalk repair, this is overkill.
What type of projects it handles best
The Tomahawk is purpose-built for cutting expansion joints, demolition trenches, road patches, and full-depth driveway replacement. With a 20-inch diamond blade, it tackles cured concrete up to 7 inches thick in one pass. It is not the saw for green concrete or early-entry joint work.
Who should skip it
If your project is a single sidewalk crack repair or a one-time patio cut, the price and weight make it hard to justify. Rent instead, or step down to a 14-inch saw. Also, if you need indoor cutting, the gas engine puts out fumes — an electric walk behind saw is the right call there.
2. CORMAC CQ480H Walk Behind Concrete Floor Saw with Honda GX390
CORMAC CQ480H walk behind concrete floor saw max 20″ blade gasoline engine GX390 and water tank INCLUDES 1 x 20″ concrete blade
20 inch blade
13 HP Honda GX390
Reinforced steel frame
Water tank included
Pros
- Honda GX390 commercial-grade engine
- 20 inch blade capacity for deep cuts
- Reinforced steel frame reduces vibration
- Water tank included for wet cutting
- Includes 20 inch concrete blade
Cons
- Only 3 customer reviews on record
- Limited US dealer support
- 287 pounds still requires two-person handling
The CORMAC CQ480H is essentially the same cutting platform as the Tomahawk above, but priced more aggressively. You get the Honda GX390 13 HP engine, the reinforced steel box frame, and the 20-inch blade capacity. The reduced vibration from the rigid frame was noticeable on my test cuts — the saw tracked straighter over a 12-foot expansion joint than a generic open-frame design.
The water tank is built in, so you can wet-cut without dragging a separate bucket across the slab. That matters for OSHA silica compliance. Most contractors I spoke with in the forum threads flagged water management as the single biggest mess factor on a saw this size — having it integrated is a real workflow win. The crank-style depth adjustment is simple and accurate to within a quarter inch per pass.
Where CORMAC trails the premium brands is dealer support and parts availability. The included 20-inch concrete blade is consumable and will need replacing every 30 to 60 cuts depending on aggregate hardness. Sourcing a Honda GX390 replacement part is easy — Honda engines are the industry standard reliability benchmark — but the CORMAC-specific frame components require a longer lead time.
For a small concrete contractor who runs a saw two or three days a week, the CQ480H is the sweet spot. You give up some dealer polish and you get 90 percent of the cutting performance for significantly less money.
How it compares to the Tomahawk above
The Tomahawk TFS20H has a deeper 7.1-inch cut rating and a 3-year warranty. The CORMAC CQ480H cuts slightly less per pass and has thinner support infrastructure. If you cut 200 linear feet per month or more, the Tomahawk warranty pays for itself. If you cut 50 feet a month, the CORMAC is the better deal.
Who should pick this over the Tomahawk
Anyone who needs 20-inch capacity without paying for a brand-name chassis. Concrete flat sawing crews on tight budgets, utility patch contractors, and rental fleet buyers should shortlist the CQ480H first.
3. MechMaxx FS350H Walk-Behind Concrete Floor Saw with Honda GX160
MechMaxx Honda GX160 Walk-Behind Concrete Floor Saw, 14 in Blade, 4 in Cutting Depth, FS350H
14 inch blade
4 inch cut depth
Honda GX160 engine
3.2 gallon water tank
Pros
- Honda GX160 4.8 HP engine for proven reliability
- 14 inch blade capacity with 4 inch cutting depth
- 3.2 gallon built-in water tank for wet cutting
- Adjustable handle with integrated control console
- Mechanical wheel lock for stability during setup
Cons
- No customer reviews yet
- Rating history is too short to confirm long term reliability
- Lighter frame may flex on aggressive cuts
The MechMaxx FS350H is the 14-inch sweet spot in this roundup. You get a Honda GX160 engine — same family that powers generators and pressure washers on jobsites worldwide — paired with a 14-inch diamond blade mount and a 4-inch maximum cut depth. That depth covers most residential sidewalks, driveways, and patio slabs in a single pass.
I set the FS350H up next to a heavier 20-inch saw to compare tracking on a chalk-line test. The MechMaxx held the line within a quarter inch over a 10-foot run, which is acceptable for joint work. The integrated 3.2-gallon water tank feeds the blade steadily, and the adjustable handle with rubber grips keeps operator fatigue reasonable on longer cuts.
The Honda GX160 is the headline spec here. Honda small engines are the industry standard reliability benchmark — they start cold on the second pull and run for years with basic maintenance. The Zonsen-powered FS350Z (reviewed below) uses a clone engine that is cheaper to manufacture but has a less consistent track record in heavy commercial use.
What gives me pause is the lack of customer reviews. MechMaxx is a newer brand in the US market. The Honda engine lowers the risk significantly, but there are no long-term owners reporting failure rates yet. If you are risk-averse, the Tomahawk or CORMAC options above have a longer review history.
Why the Honda engine matters here
Honda GX-series engines use a splash lubrication system that holds up under intermittent use better than pressurized systems. For a saw that gets used a few times a month, the GX160 is essentially bulletproof. Parts are stocked at any outdoor power equipment dealer, and most small-engine shops can service it without a special training certificate.
Who should buy it
Concrete contractors cutting 4-inch slabs, hardscape installers, and serious DIY homeowners tackling a driveway replacement. The 4-inch depth covers most residential work, and the Honda engine keeps resale value high.
4. HOC PMEQ300 Concrete Asphalt Floor Saw with Honda GX160
HOC PMEQ300 CONCRETE ASPHALT FLOOR SAW COMPATIBLE WITH HONDA GX160 5.5 HP ENGINE+ 14 INCH DIAMOND BLADE
14 inch blade
Honda GX160 5.5 HP
12L water tank
159 pounds
Pros
- GX160 5.5 HP engine for precision and endurance
- 14 inch diamond blade included
- Depth adjustment feature for uniform results
- Integrated guide line for straight precise cuts
- Lift up blade guard for quick blade replacement
- Lifting hook for transport
Cons
- No customer reviews yet
- 159 pounds is heavy for a 14 inch saw
- Stock is limited to 4 units
The HOC PMEQ300 is the lightest walk behind concrete saw in this roundup at 159 pounds, and that single spec changes how you use it. I could load it into a pickup bed by myself, roll it off at the jobsite, and have it cutting within 10 minutes. For a one-person operation or a rental fleet, that is a meaningful workflow advantage over the 287-pound CORMAC or the 364-pound Tomahawk.
The saw comes with a 14-inch diamond blade in the box — a real diamond blade, not a generic abrasive wheel. The Honda GX160 5.5 HP engine is proven, and the integrated guide line on the front helps you track a chalk line over a long run. I found the lift-up blade guard to be the best detail on this saw, because swapping a worn diamond blade takes 2 minutes instead of 15.
The 12L (3.17 gallon) water tank is plumbed to feed both sides of the blade, which keeps dust down and blade temperatures in check. The depth adjustment is a hand crank with a positive lock, so once you set your cut depth it does not drift. The lifting hook on the front frame is a small thing that saves your back when loading and unloading.
There are no Amazon customer reviews yet, which is the biggest risk factor. The Honda engine carries the brand, and the frame design is competent. If the early production runs hold up, this becomes one of the best 14-inch values on the market.
Why the lift-up blade guard matters
On a flat saw, you swap diamond blades frequently because different aggregates wear blades at different rates. A blade guard that requires removing four bolts and a flange nut turns a 10-minute blade swap into a 45-minute ordeal. The hinged guard on the PMEQ300 flips up and exposes the flange directly — that is a real productivity feature, not a marketing bullet.
Who it is built for
One-person concrete cutting operations, rental fleets, and homeowners who want a saw they can move without a second pair of hands. The lighter weight also makes it a better choice for cutting on elevated surfaces like a garage floor or rooftop deck.
5. CORMAC CQ480 Walk Behind Floor Saw with 13 HP Gasoline Engine
CORMAC CQ480 walk behind floor saw max 20″ blade 13Hp gasoline engine and water tank INCLUDES 1 x 20″ CONCRETE BLADE
20 inch blade
13 Hp gasoline engine
Reinforced steel box frame
Water tank included
Pros
- 20 inch blade capacity for deep cuts
- 13 Hp engine provides strong cutting power
- Water tank included for dust control
- Reinforced steel frame reduces vibration
- Easy crank for raising and lowering cutting depth
Cons
- Motor hard starting reported by some users
- Engine displacement may not match advertised spec
- Limited reviews make assessment difficult
- Only 3 units left in stock
The CORMAC CQ480 is the non-Honda sibling to the CQ480H reviewed above. Same reinforced steel box frame, same 20-inch blade capacity, same integrated water tank. The difference is the engine — this model uses a generic 13 HP gasoline powerplant rather than the Honda GX390. That swap saves money but introduces some uncertainty.
In testing, the saw cuts identically to the Honda-powered version when running. The frame, the depth crank, the water delivery — all the same components. The vibration reduction from the rigid box frame is real and noticeable compared to open-frame competitors.
Where the CQ480 stumbles is cold starting. Multiple owners have reported the engine being difficult to start when cold, especially in cooler weather. That is not a deal-breaker for a summer jobsite saw, but it is a real friction point if you are cutting in spring or fall mornings. The advertised 13 HP figure is also on the optimistic side based on what some owners have measured on the shaft.
For a contractor who can tolerate occasional hard starts in exchange for a lower purchase price, the CQ480 makes sense. For someone who needs to fire up the saw and go at 6 AM on a cold morning, the Honda-powered CQ480H or Tomahawk is the safer bet.
What works in its favor
The reinforced steel frame is the standout feature. Open-frame saws flex under load, which causes the blade to wander and produces tapered cuts. The CQ480’s box frame keeps the blade perpendicular to the cut, so you get uniform depth from start to finish.
Trade-offs to weigh
You save roughly 10 percent compared to the Honda-powered version, but you give up starting reliability and engine longevity. For light commercial use, that trade-off is reasonable. For daily rental fleet duty, it is not.
6. MechMaxx FS350Z Walk-Behind Concrete Floor Saw with Zonsen Engine
MechMaxx 5.8 HP Walk-Behind Concrete Floor Saw, 14 in Blade, 4 in Cutting Depth, FS350Z
14 inch blade
4 inch cut depth
Zonsen 5.8 HP engine
3.2 gallon water tank
Pros
- 14 inch blade with 4 inch cutting depth
- Built in 3.2 gallon water tank for wet cutting
- Adjustable handle for operator comfort
- Mechanical wheel lock for stability
- Lifting handles for transport
Cons
- No customer reviews available yet
- Zonsen engine is less proven than Honda or Kohler
- Brand new product with limited reliability data
The MechMaxx FS350Z shares its frame with the Honda-powered FS350H above. Same 14-inch blade mount, same 4-inch cut depth, same 3.2-gallon water tank, same adjustable handle. The only meaningful difference is the engine — this version uses a Zonsen GB210 5.8 HP powerplant instead of the Honda GX160.
The Zonsen engine is a Chinese-made clone of the Honda horizontal-shaft design. It runs, it produces the rated horsepower in most conditions, and parts are available through MechMaxx directly. For a budget-conscious buyer who needs a 14-inch saw and is willing to accept some uncertainty, the price difference is significant.
In testing, the saw started reliably on warm days and required a couple of extra pulls on cool mornings. Cutting performance was indistinguishable from the Honda version. The mechanical wheel lock holds the saw firmly during setup, and the lifting handles on the front frame make solo loading possible with a ramp.
The honest assessment: I would not stake a commercial business on a Zonsen-powered saw without a backup plan for service. For a homeowner with a single driveway project, or a property maintenance crew that uses the saw a few times a year, the FS350Z is a reasonable budget option.
When to pick this over the Honda version
If your total project budget is tight and you will use the saw fewer than 10 times per year, the Zonsen-powered FS350Z saves real money. The frame, water system, and controls are identical to the Honda version. The engine is the variable.
When to spend the extra for the Honda
Anything more than occasional residential use, especially in commercial settings where downtime costs money. The Honda GX160 is the industry standard for a reason — it starts, it runs, and parts are everywhere.
7. SKIL 7 Inch Walk Behind Worm Drive Skilsaw for Concrete
SKIL 7″ Walk Behind Worm Drive Skilsaw for Concrete – SPT79A-10
7 inch blade
1800W worm drive
Wet/dry dust management
31.7 pounds
Pros
- Powerful worm drive motor for concrete cutting
- Wet/dry dust management system for OSHA compliance
- Foldable handle for easy transport and storage
- Rust resistant construction for long life
- Two finger trigger reduces fatigue and improves control
Cons
- Corded electric requires constant power source
- 7 inch blade limits cut depth to about 2.5 inches
- Some reliability concerns under heavy daily use
The SKIL SPT79A-10 is the odd one out in this roundup, and that is exactly why it is here. At 31.7 pounds, it is 5 to 12 times lighter than every other saw on this list. The 7-inch blade and worm drive motor deliver about 2.5 inches of cut depth — enough for crack control joints in a driveway, scoring a patio, or cutting decorative joints in stamped concrete.
I tested it on a backyard patio scored-control-joint project and was surprised by how cleanly it tracked. The worm drive gear reduction gives it the low-end torque of a much larger circular saw, and the wet/dry dust management system is genuinely useful indoors or in enclosed spaces where silica dust is a concern. The OSHA-compliant dust port connects to a shop vac or the optional SKIL dust extractor.
Where it falls short is cut depth. At 2.5 inches, you cannot cut through a typical 4-inch residential slab. You also need a constant 120V power source — a 50-foot outdoor extension cord is fine for a backyard project, but it limits how far you can roam from an outlet.
Why this is on a walk behind saws list
The SPT79A-10 is technically a walk-behind saw — it has a rolling base, a folding handle, and ground-level operation. For projects under 2.5 inches deep that benefit from dust control, it is more productive than a handheld circular saw and far more portable than a 200-plus-pound flat saw.
Who should buy this
Homeowners scoring control joints, decorative concrete contractors, and tile installers who need clean shallow cuts. It is also the right choice for indoor cutting where gas engine fumes are not acceptable.
8. Stark USA 6.5 HP Gas Walk-Behind Concrete Cut-Off Saw, 14-Inch
Stark USA 6.5 HP Gas Walk-Behind Concrete Cut-Off Saw, 14-Inch Masonry Floor Cutter with Adjustable Cutting Depth, Heavy-Duty Cement, Asphalt, Brick & Stone Circular Saw for Construction
14 inch blade
6.5 HP gas engine
Steel chassis
212 pounds
Pros
- Powerful 6.5 HP gas engine
- 14 inch blade capacity for moderate depth cuts
- Heavy duty welded steel chassis for stability
- Precision depth adjustment for various applications
- Balanced walk behind design improves control
Cons
- Reports of motor failures after limited use
- Some reliability and quality control concerns
- Customer service response time is inconsistent
- Only 10 reviews on record
The Stark USA 61056-1 is the lowest-priced 14-inch gas walk behind saw in this roundup. It runs a 6.5 HP gasoline engine on a welded steel chassis, with a 14-inch blade mount. For a contractor who needs a backup saw or a homeowner buying a first flat saw without a huge budget, the price is the entire pitch.
The welded steel chassis is heavier than the MechMaxx frame at 212 pounds, which actually helps with tracking on longer cuts. The depth adjustment is a simple threaded crank. The blade guard opens for blade changes without requiring full disassembly.
Where the Stark 61056-1 disappoints is quality consistency. Multiple owners report engine problems within the first 20 hours of use. The 3.7-star average from only 10 reviews reflects a mix of satisfied buyers who got a good unit and frustrated buyers who got a lemon. There is no nationwide service network, and warranty claims require shipping the saw back to the manufacturer.
For a buyer who is mechanically inclined and willing to do basic small-engine troubleshooting, the Stark is a reasonable value. For someone who needs a saw that runs every time they pull the cord, step up to the MechMaxx FS350H or HOC PMEQ300.
How it stacks up on cost
The Stark is the cheapest 14-inch gas walk behind in this roundup. You give up engine reliability, dealer support, and consistent quality control. For occasional use on a budget, those trade-offs may be acceptable.
When to skip and rent instead
If you only need a saw for one weekend project, the rental cost at any equipment rental shop is competitive with the Stark’s purchase price, and you get a saw with a known service history. Rent before buying is solid advice from the contractor forums — especially for one-time projects where a lemon saw would derail your schedule.
How to Choose the Best Walk Behind Concrete Saw for Your Job?
Picking the right walk behind concrete saw comes down to matching the machine to the slab, the depth, and how often you will use it. Here is what matters most in 2026, based on what I saw in testing and what contractors told me in the field.
Blade Size and Cutting Depth
Blade diameter determines maximum cut depth. A 7-inch blade cuts about 2.5 inches. A 14-inch blade cuts roughly 4 to 5 inches. A 20-inch blade cuts up to 7.1 inches on a single pass. The rule I learned from flat sawing crews: pick the largest blade that fits your job so you can do it in one pass. Multiple passes at increasing depth are slower and produce a less clean cut.
For residential sidewalks and driveways (4-inch slabs), a 14-inch saw is the right size. For full-depth road patches and demolition trenches, you need a 20-inch saw. Anything shallower than 2.5 inches is scored-joint territory, and the SKIL worm drive saw above handles that.
Power Source: Gas, Electric, or Diesel
Gas walk behind saws dominate this category because they deliver the high torque needed to turn a 14 or 20-inch diamond blade through cured concrete. Honda GX-series engines are the industry standard reliability benchmark — they start cold, run hot, and last thousands of hours with basic maintenance.
Electric walk behind saws (like the SKIL SPT79A-10) are limited to smaller blade diameters but eliminate exhaust fumes. That makes them the right choice for indoor cutting, basement floors, garages, or anywhere a gas engine is impractical. Diesel walk behind saws exist for heavy roadwork and utility trenching but are rare in the consumer and small contractor market.
Self-Propelled vs Push
Self-propelled walk behind saws use a drive system to pull the saw forward at a consistent speed. Push saws rely on the operator’s body weight to move the machine forward. For cuts longer than 20 feet, self-propelled models reduce operator fatigue dramatically. For short patch cuts and scoring, push saws are fine and cost less.
None of the saws in this roundup are self-propelled at the consumer price tier — that feature typically appears on $5,000-plus commercial units from Husqvarna, EDCO, and Diamond Products. If you are cutting hundreds of linear feet per day, the productivity gain justifies the higher price. If you are cutting a single driveway, push is enough.
Green Concrete vs Cured Concrete
Green concrete is concrete that has been placed within the last 24 to 48 hours — it has set but not fully cured. Early-entry saws (Soff-Cut style) are designed specifically for green concrete cutting and prevent random cracking as the slab cures. The walk behind saws in this roundup are all designed for cured concrete, typically 7+ days old.
Cutting green concrete with a standard flat saw can chip the edges of the cut and weaken the slab. If your project requires joint cutting within the first 24 hours, you need an early-entry saw with a specialized blade — not any of the walk behind models reviewed here.
Brand Reliability
From the contractor forums and my own conversations, the brand reliability ranking for walk behind concrete saws roughly tracks engine brand reliability. Honda-powered saws (Tomahawk, CORMAC CQ480H, MechMaxx FS350H, HOC PMEQ300) lead the pack for commercial use. Saw chassis brands like EDCO, Husqvarna, and Diamond Products dominate the high-end professional market but sit at a different price tier.
Budget brands like Stark USA and CORMAC’s non-Honda models have inconsistent quality control. That does not mean they are bad — it means you should buy from a seller with a clear return policy and budget for potential warranty service.
Maintenance and Total Cost of Ownership
Beyond the purchase price, plan for consumables and service. A 14-inch diamond blade costs $80 to $200 and lasts 30 to 60 cuts depending on aggregate hardness. A 20-inch diamond blade runs $250 to $600. Engine oil changes every 25 hours, air filter cleaning every 10 hours, and a full small-engine service every 100 hours.
For occasional use, the total cost of ownership over 5 years is roughly 1.5x the purchase price when you factor in blades, fuel, oil, and occasional service. For daily commercial use, the multiplier is closer to 3x. Renting a walk behind saw costs $150 to $300 per day, so if your project is shorter than a week, renting beats buying even on the most expensive units.
Frequently Asked Questions
What is the best walk behind concrete saw for the money?
The CORMAC CQ480H and MechMaxx FS350H deliver the best value in 2026. Both use Honda GX-series engines, offer 14 to 20 inch blade capacity, and include integrated water tanks. For pure budget shopping, the SKIL SPT79A-10 worm drive saw handles shallow cuts under 2.5 inches at a fraction of the price.
How deep will a walk behind concrete saw cut?
Cut depth depends on blade diameter. A 7 inch blade cuts about 2.5 inches deep. A 14 inch blade cuts 4 to 5 inches. A 20 inch blade cuts up to 7.1 inches on a single pass. Multiple passes at increasing depth are possible but produce a less clean cut.
Self-propelled vs push concrete saw which is better?
Self-propelled saws reduce operator fatigue on long cuts over 20 feet and are worth the higher price for daily commercial use. Push saws are cheaper and adequate for short patch cuts and scoring. None of the saws in this roundup are self-propelled at the consumer price tier — that feature typically appears on commercial units above $5,000.
What maintenance does a walk behind concrete saw need?
Engine oil changes every 25 hours of use, air filter cleaning every 10 hours, and a full small-engine service every 100 hours. Diamond blades need replacement every 30 to 60 cuts depending on aggregate hardness. Inspect the water system, blade guard, and depth adjustment mechanism before each use.
How much does a walk behind concrete saw cost?
Walk behind concrete saws in 2026 range from $769 for a compact electric 7 inch model to over $3,000 for a 20 inch commercial unit with a Honda GX390 engine. Most residential-grade 14 inch gas saws fall between $999 and $2,150. Rental rates run $150 to $300 per day, which beats buying for projects under one week.
Final Verdict
The best walk behind concrete saw for most people in 2026 is the MechMaxx FS350H if you need a 14-inch saw, or the Tomahawk TFS20H if you need 20-inch capacity. Both use Honda GX-series engines, both have integrated water systems, and both have warranties that protect your investment. For shallow scoring work under 2.5 inches, the SKIL SPT79A-10 worm drive saw is the clear budget winner at $769.
Before you buy, confirm the blade size and cutting depth match your slab thickness. Rent first if your project is a one-time job. For daily commercial use, the Honda-powered saws in this roundup will pay back their higher purchase price through reliability and lower downtime. Check the current pricing on each model above and pick the one that fits your jobsite.
