Frequently Asked Questions

Q: Can this diamond hole saw kit be used on ceramic and porcelain tiles?

A: Yes! The diamond-coated drill bits are specifically designed for hard surfaces including ceramic, porcelain tile, glass, marble, granite, and natural stone. Using a low drill speed with water cooling will give you the cleanest results on ceramic and porcelain.

Q: What drill is compatible with this 12-piece diamond drill bit set?

A: The hole saws in this kit feature standard shank sizes compatible with most hand drills and drill presses. Always check your drill's chuck capacity before use — the bits suit typical domestic and professional drills commonly available on the market.

Q: Do I need water when using these diamond drill bits on glass or marble?

A: Using water as a coolant is strongly recommended when drilling glass, marble, granite, or any dense stone. Water reduces heat build-up, prevents cracking or chipping of the material, and significantly extends the working life of your diamond-tipped bits.
