Frequently Asked Questions

Q: What materials can these four-edge serrated drill bits cut through?

A: These drill bits are designed to handle a wide range of hard materials including tile, ceramic, concrete, glass, metal, hardwood, and aluminum alloys. The serrated four-edge tip geometry makes them especially effective at cleanly penetrating hard, brittle surfaces like tile and ceramic without cracking.

Q: Are these drill bits compatible with standard drills?

A: Yes — these bits feature a standard shank compatible with most household and professional power drills. They also work seamlessly with magnetic chuck adapters for a wobble-free, secure fit during use.

Q: What sizes are available in this drill bit set?

A: The set is available in a range of sizes from 6mm to 12mm, giving you versatility for different drilling tasks — from small pilot holes to larger fixture fittings on tiles, concrete, or metal surfaces.

Q: How do I get the best results when drilling into tile or ceramic?

A: For best results on tile or ceramic, start at a slow speed to allow the serrated tip to grip the surface before increasing speed. Apply steady, even pressure and avoid excessive force. Using a small piece of masking tape at the drill point can help prevent slipping on glazed surfaces.
