Frequently Asked Questions

Q: What materials can these diamond-tipped drill bits cut through?

A: These diamond-tipped drill bits are designed to cut through hard, brittle materials including ceramic tile, porcelain, glass, granite, marble, and stone. They are not recommended for use on standard wood or soft plastics, where conventional bits are more suitable.

Q: Can I use these drill bits with a standard electric drill?

A: Yes! These bits feature standard shank sizing compatible with most corded and cordless electric drills and drill presses. For best results when drilling through glass or tile, use a slow speed setting and apply water to the drilling area to manage heat.

Q: Are these drill bits suitable for wet and dry drilling?

A: These bits support both wet and dry drilling. Using water as a coolant during wet drilling can significantly extend the life of the diamond tip and produce cleaner results, especially when working with glass or polished stone surfaces.

Q: How do I maintain and extend the life of my diamond drill bits?

A: To maximise bit life, apply consistent but moderate pressure — avoid forcing the bit. Use water cooling where possible, especially on glass and tile. Store bits in a dry place and keep them free of debris between uses. Avoid overheating, which can degrade the diamond coating over time.
