Diamond Saw Blades

The right diamond saw blade depends on one thing: the material you cut. Porcelain and ceramic tile need a thin continuous rim like the TILE LEOPARD. Granite and hard stone call for a turbo rim. Concrete, brick, and block are the job of a segmented blade like the CONSTRUCTION RACCOON. All PRODIAMANT diamond saw blades fit standard US angle grinders and tile saws with a 7/8" arbor and included 5/8" reducer. Pick the blade that matches your material, not your machine.

Which Blade for Which Material

Match the rim to the material. That is the whole decision.

  • TILE LEOPARD – a thin continuous rim for porcelain, ceramic, and glazed tile. The closed rim cuts slower but leaves a clean edge with minimal chipping.
  • TURBO PANTHER – a turbo rim for granite and other hard stone. The serrated turbo rim clears debris faster than a continuous rim while keeping the cut edge tight.
  • CONSTRUCTION RACCOON – a segmented rim for concrete, brick, and block. The gullets between segments move dust out and keep the blade cool during fast, aggressive cuts.

If a job mixes materials, carry two blades and swap. A segmented blade chips tile. A continuous rim glazes over in cured concrete. There is no single blade that does both well.

Arbor and Machine Fit

PRODIAMANT diamond saw blades use the standard 7/8" arbor and ship with a 5/8" reducer ring, so they mount on common US angle grinders and tile saws without extra adapters. Before mounting any blade, compare the maximum RPM printed on the blade with the no-load speed of your machine. The blade rating must be equal to or higher than the machine speed. Never run a blade above its rated RPM, and never remove the guard to make a larger blade fit.

Wet or Dry Cutting

All three blades cut dry on an angle grinder. Work in intervals: cut, back off, let the blade run free for a few seconds to cool. Continuous dry cutting overheats the rim and shortens blade life. For long cuts in tile or stone, run the blade wet on a tile saw – water cools the rim and improves cut quality. On concrete and masonry there is a second reason to control dust: OSHA’s silica rule (29 CFR 1926.1153) requires water delivery or vacuum dust collection for most saw work on US jobsites. Plan water or a vacuum before you start the cut, not after.

Frequently Asked Questions

Can I use one diamond saw blade for both tile and concrete?
Not with good results. A segmented concrete blade chips porcelain and tile, and a continuous-rim tile blade glazes over in cured concrete. Use the TILE LEOPARD for tile and the CONSTRUCTION RACCOON for concrete and masonry.
Do these diamond saw blades fit a standard US angle grinder?
Yes. They come with a 7/8" arbor and an included 5/8" reducer ring, which covers common US angle grinders and tile saws. Always check that the blade diameter matches your guard.
What is the difference between a continuous, turbo, and segmented rim?
A continuous rim cuts cleanest and slowest, ideal for porcelain and ceramic. A turbo rim cuts faster in hard stone like granite while keeping a tight edge. A segmented rim cuts fastest and coolest in concrete, brick, and block.
Can I cut dry, or do I need water?
Dry cutting works on an angle grinder if you cut in intervals and let the blade cool. For long cuts, wet cutting on a tile saw gives a cleaner edge and longer blade life. On concrete and masonry, OSHA 29 CFR 1926.1153 requires water or vacuum dust collection for most saw work.
How do I know when a diamond saw blade is worn out or glazed?
If the blade slows down and starts to rub instead of cut, the rim is likely glazed. A few short cuts in an abrasive material such as a soft brick can re-expose the diamonds. If the rim height is visibly gone, replace the blade.
