Choosing a brick cutting saw blade means matching a diamond masonry blade to four things: blade diameter, arbor size, the saw’s maximum RPM, and whether you’re cutting wet or dry.
Brick is abrasive stone. Wood and metal blades will throw teeth, overheat, and put shrapnel in the air. A diamond blade grinds through masonry, and it’s the only blade type built for the job. Four numbers decide whether the blade fits your saw; get them right and the rest is picking a rim style.
What Type of Blade Actually Cuts Brick?
A diamond blade is the correct choice for brick and block. Diamond segments bonded to a steel core grind the brick away rather than slicing it. Hilti’s SPX masonry blade is a good example of the labeling to look for — its product page describes it for masonry, brick, and sand limestone. Applied Diamond’s PRO-MASON is another blade specified for masonry work.
Buy a blade whose packaging or product page says brick or masonry. A general-purpose blade listing tile, concrete, and brick as afterthoughts is a compromise you’ll feel in cut quality and lifespan.
Match These Four Numbers Before You Buy
Diameter, arbor size, and maximum RPM must all match your saw, and the blade has to be compatible with the saw’s guard.
- Diameter — Must fit inside the saw’s guard. A blade that rubs the guard is dangerous; one too small won’t reach full cutting depth.
- Maximum RPM — The blade’s printed max RPM must be equal to or higher than your saw’s rated speed. A blade rated below your tool’s RPM can shatter. This is the most dangerous mismatch.
- Arbor size — The center hole must match the saw’s arbor. Adapters exist, but a loose fit introduces wobble, ruining the cut and stressing the blade.
- Equipment class — Some blades are sold only for specific machine types. A blade for a masonry saw may not be approved for a hand-held circular saw, even if the diameter lines up.
Confirm all four against the blade’s spec sheet and your saw’s manual before ordering. If a listing doesn’t state a max RPM, buy a different blade.
| Blade Style | Best For | Cut Method |
|---|---|---|
| Segmented rim | Hard brick, fast rough cuts | Dry |
| Turbo rim | Faster cuts with a smoother finish | Dry or wet |
| Continuous rim | Clean edges, masonry work | Wet |
Dry Cutting or Wet Cutting?
Segmented and turbo blades handle most dry cutting; continuous rim blades are typically used wet in masonry work.
Segmented blades have gaps that let air reach the cut to carry heat away, making them common for hard brick and dry cuts. Turbo blades use a continuous rim with small notches, cutting faster with a smoother finish in some applications. Continuous rim blades run wet — water cools the blade and suppresses silica dust. Wet saws and masonry saws that plumb water to the blade are built for this.
Set the blade about 1/4 to 1/2 inch below the brick rather than burying it. For deep cuts, make multiple shallow passes. Back the blade out after roughly 30 seconds to let it cool, then continue. Forcing the blade causes chipping, overheating, and faster wear — let the blade do the work.

Mistakes That Ruin Blades and Cuts
- Buying a blade that isn’t rated for masonry.
- Ignoring the RPM limit or fitting the wrong diameter for the saw’s guard.
- Using the wrong arbor size, introducing wobble.
- Running a dry-cut blade in a wet-cutting workflow, or the reverse, without checking what the manufacturer allows.
- Pushing the blade through the brick instead of guiding it and letting the diamond grind.
Eye protection, hearing protection, and a dust mask are standard gear for any masonry cut — dry cutting sends fine silica dust into the air, and the mask is the one people skip. Follow the blade and saw manufacturer’s instructions for everything else.
FAQs
Can I cut brick with a regular circular saw blade?
No. Wood and metal blades aren’t built for abrasive masonry and will be destroyed almost immediately, throwing fragments. To use a circular saw on brick, fit it with a diamond masonry blade rated for the saw’s RPM and approved for that machine class.
How do I know if a blade fits my saw’s RPM?
Check the maximum RPM printed on the blade against the rated speed on your saw’s label or manual. The blade’s max RPM must be equal to or higher than the tool’s rating. If the blade doesn’t state a max RPM, don’t use it on a powered saw.
Should I cut brick wet or dry?
It depends on your blade and saw. Segmented and turbo rims commonly handle dry cuts; continuous rim blades are typically used wet. Wet cutting controls both heat and the silica dust brick cutting produces, so if your saw supports water feed, it’s safer indoors or in enclosed spaces.
