Frequently Asked Questions

Q: What materials can this diamond drill bit cut through?

A: This diamond-tipped drill bit is designed to cut through hard, brittle surfaces including ceramic tile, porcelain tile, glass, marble, and granite. It is not suitable for wood, metal, or standard concrete.

Q: Do I need to use water when drilling with this bit?

A: Yes — especially when drilling through glass or polished marble, using water as a coolant is highly recommended. It keeps the bit from overheating, extends its lifespan, and results in a cleaner, chip-free hole.

Q: Will this fit my standard power drill?

A: Yes. The bit features a universal shank that is compatible with most standard handheld power drills and drill presses. Always ensure the chuck size matches the shank diameter of your chosen bit size before use.

Q: How do I prevent the tile from cracking while drilling?

A: Start at a low speed to score the surface before increasing to your working speed. Apply light, even pressure and use water cooling. Avoid forcing or rocking the drill — let the diamond grit do the work for a smooth, crack-free result.
