What the AI looks for in Diamond Saw Blades
- Rim type
- Continuous rim for tile and porcelain. Segmented for concrete and masonry. Turbo for a mix of speed and finish. Rim type decides chipping and cutting speed.
- Wet vs dry rating
- Use dry-rated blades only for dry cutting. Wet-only blades need water. Running a wet-only blade dry overheats it and can strip the segments.
- Arbor and RPM
- Many blades are 7/8 in arbor with a 5/8 in knockout. The rated RPM must be at or above the tool's speed. Grinders spin very fast, so an under-rated blade is dangerous.
- Bond vs material hardness
- Soft-bond blades for hard materials. Hard-bond blades for abrasive materials like asphalt or green concrete. A mismatched bond glazes over or wears out quickly.
Brands that matter

- DeWalt: Broad line for grinders and cut-off saws.

What to avoid

Questions
Blade stopped cutting but looks fine?
The diamonds have glazed over. A few cuts into an abrasive block or concrete paver re-exposes them.
