Concrete Saw Guides
Even the best diamond blade underperforms with bad technique. These guides cover cutting methods, joint timing, saw selection, dust control, and safety so your crew gets clean, efficient, OSHA-compliant cuts every time.

Concrete Saw Types
Angle Grinders (4.5-7″)
The most accessible concrete cutting tool — most contractors already own one. Cuts up to about 2 inches deep with the right diamond blade. Always dry-cut for safety. Best for wall penetrations, paver cutting, scoring lines, and small repair work.
Handheld Cut-Off Saws (12-16″)
The contractor workhorse. Stihl TS 420, Husqvarna K 770/K 970, Hilti DSH 700-X, Milwaukee MX FUEL COS350. Cuts 4.5-6 inches deep with a 14-inch blade. Handles slabs, walls, block, and reinforced concrete. Available in gas and battery; electric corded is rare on job sites.
Walk-Behind Flat Saws (14-36″)
Deep cutting for expansion joints, road work, demolition, and utility trenches. Ride-on or push. Always wet. Cuts up to 14 inches deep on the largest saws. Rental is common for one-off jobs.
Wet Tile Saws
Table-mounted wet saws for tile, stone, and delicate cuts. Used in masonry for brick and paver work. Not suitable for slab work.
For the full saw-selection framework, see our Concrete Saw Buying Guide.
Safety and Compliance
Concrete cutting is a high-risk activity — silica dust, blade-related injuries, and electrical hazards with wet cutting. The non-negotiables:
- Safety glasses + face shield on every cut (not optional)
- Hearing protection (25+ NRR — concrete saws run 95-115 dB)
- Steel-toe boots, cut-resistant gloves
- OSHA silica compliance: wet cutting OR 99% vacuum dust collection
- Inspect blade for cracks/missing segments before every use
- Match blade max RPM to saw rated speed
- Never cut near power lines with wet saws
For detailed protocols see our Concrete Saw Safety Checklist and Silica Dust Safety Guide.
Frequently Asked Questions
What saw do I need to cut concrete?
Match the saw to the job. Angle grinders (4.5-7") work for light cuts up to 2" deep. Handheld cut-off saws (12-16" blade) handle slabs, block, and most contractor cuts. Walk-behind flat saws (14-36" blade) cut deep for expansion joints, demolition, and road work. Wet tile saws handle small tile, stone, and delicate cuts.
Do I need a gas or electric concrete saw?
Gas cut-off saws (Stihl TS 420, Husqvarna K 770) are the contractor default — unlimited runtime, no power cord, handle wet cutting safely. Battery-electric saws (Milwaukee MX FUEL COS350, Husqvarna K 1 PACE) are catching up fast — lower emissions, indoor-safe, but battery runtime limits all-day production. Corded electric works for fixed-location cutting but not field work.
Can I cut concrete with a circular saw?
Yes, with a diamond blade rated for the saw's RPM and a depth of cut under 2 inches. A standard 7-1/4" circular saw with a masonry diamond blade cuts about 2" deep. Not ideal for daily work — the saw wasn't built for the load. For anything more than occasional cuts, use an angle grinder or cut-off saw.
What PPE do I need for concrete cutting?
Minimum: ANSI Z87 safety glasses, face shield, hearing protection (25+ NRR), cut-resistant gloves, and steel-toe boots. For silica dust compliance (OSHA 29 CFR 1926.1153): a P100 respirator for dry cutting without water OR a dust shroud with 99% vacuum dust collection. Wet cutting handles the silica issue but creates slip hazards and slurry cleanup.
