Choosing the Right Tool

Which diamond saw blade fits my material?

Porcelain and tile: thin continuous rim (Tile Leopard). Granite and hard stone: turbo rim (Turbo Panther). Concrete, brick and masonry: segmented rim (Construction Raccoon). Full guide: Which Diamond Saw Blade for Which Material?

What arbor sizes do your blades have?

Our angle-grinder blades come with a 7/8" (22.23 mm) arbor and include a 5/8" reducer — they fit most U.S. angle grinders and circular saws. Threaded tools (mortar rake, cup wheels) use the standard 5/8"-11 spindle, no adapter needed. More: Arbor Sizes Explained.

Can I cut wet and dry?

Most of our blades handle both. Dry cutting: work in 30–60 second intervals and let the blade spin free to cool. Wet cutting extends blade life and controls dust — details in Wet vs. Dry Cutting.

Is the Carbide Mortar Rake right for hard cement mortar?

It excels on lime and soft-to-medium cement mortar — ideal for repointing older brickwork. On very hard Portland cement joints, work in shallow passes or use a diamond tuck point blade instead. Honest answer, fewer surprises.

Safety

What safety gear do I need?

ANSI Z87.1 eye protection, hearing protection and a NIOSH-approved respirator. Cutting or grinding masonry releases crystalline silica dust — use water or a dust shroud with HEPA vacuum per OSHA rules (29 CFR 1926.1153). Guide: What OSHA Requires.

Do your blades meet a safety standard?

Yes — every PRODIAMANT diamond saw blade and diamond cup wheel is manufactured to EN 13236, the strict European safety standard for diamond and other superabrasive tools. It sets requirements for maximum operating speed, mechanical strength and safety markings. Always observe the maximum RPM of both the blade and your machine.
