Frequently Asked Questions

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

A: These drill bits are designed to work on a wide range of hard surfaces including ceramic tile, porcelain tile, marble, granite, glass, quartz, brick walls, and stone. The diamond grit tip and carbide construction make them effective across all these materials.

Q: Do I need a special drill to use these hex shank bits?

A: No special drill is required. The 1/4-inch hex shank is compatible with most standard power drills and impact drivers. The anti-slip hexagonal design ensures a secure fit in virtually any drill chuck.

Q: Do I need to add water or cutting fluid when drilling tile?

A: Not necessarily. These bits feature a built-in cooling wax core that automatically releases lubricant during drilling to keep the bit cool and reduce dust. For extended drilling sessions or very hard materials like thick marble or granite, adding a small amount of water to the drill site can further extend bit life.

Q: What sizes are included in the 5-piece set?

A: The set includes five bits in the following diameters: 6mm, 8mm, 10mm, 12mm, and 14mm — giving you the range you need for anchors, fixtures, outlets, and decorative hardware installations.
