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 (grout cutter, 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 Grout Cutter 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.
Are your blades certified?
Yes — our diamond blades are manufactured to EN 13236, the safety standard for superabrasive tools. Always observe your machine's maximum RPM.
