Why this matters
-
Durable performance on challenging materials: Diamond grit cuts through porcelain, ceramic, stone, and glass with less wear and longer life than traditional carbide bits.
-
Cleaner holes: The diamond matrix helps minimize spalling and chipping, producing neater openings in glossy or brittle surfaces.
-
Faster setup: The Quick-Change system reduces downtime when you need to swap bits during complex installations.
Tips for best results
- Secure workpieces firmly and use steady, even pressure—let the diamond grit do the cutting work rather than forcing the bit.
- Keep the cutting zone cool with light water or coolant, especially when drilling through glass or dense stone, to prevent overheating.
- Start with a pilot guide or center-marked hole to ensure accurate alignment before the full cut.
- Clear debris frequently to maintain cut quality and prolong blade life.
