Questions about this product

Will these M14 core bits fit my grinder or drill?
The M14 thread screws directly onto standard angle grinders and drill chucks with an M14 adapter. That gives a wobble-free, controlled hold. Run them at 500 to 3000 RPM depending on the material.
What materials are these diamond core bits made for?
They drill clean holes in porcelain tile, granite, marble, ceramic, and natural stone. The 6-70mm range covers small plumbing fittings up to larger conduit holes. They're built for dry drilling, so no water cooling is needed in most hard materials.
How do I keep these dry diamond bits from overheating?
Even though they're rated for dry use, pull the bit out every few seconds to clear dust and let heat escape. This protects the brazed diamond segments and extends bit life. Ease off the pressure and let the diamond do the cutting.
