Frequently Asked Questions

Q: What materials can this diamond drill bit and hole saw kit cut through?

A: This 12-piece diamond drill bit kit is designed to cut through glass, marble, granite, ceramic tile, porcelain, and natural stone. The industrial diamond-tipped coating makes it effective on hard, abrasive surfaces that standard steel drill bits cannot handle.

Q: What size holes can I drill with this kit?

A: The kit covers a range of hole sizes from 6mm to 35mm, making it suitable for everything from small anchor holes to larger openings needed for plumbing fixtures, taps, or decorative inserts in tile and stone.

Q: Do I need to use water when drilling with these diamond bits?

A: Yes — it is strongly recommended to use water as a coolant when drilling with diamond bits on glass, stone, or ceramic. Water reduces heat buildup, extends bit life, and helps produce cleaner, chip-free holes. The included hand tools help create a water reservoir around the drill point for safer use.

Q: Is this kit suitable for beginners as well as professionals?

A: Absolutely. The kit is designed for both DIY enthusiasts tackling home improvement projects and professional tradespeople who need reliable, repeatable results. The included hand tools and wide size range make it easy to get started straight away.
