Questions about this product
- What materials can these diamond hole saws drill?
- They are made for tile, marble, glass, granite, porcelain, and ceramic. The diamond-coated edge grinds through these hard surfaces. They are not meant for metal, wood, or brick masonry.
- Do I need water when drilling with these bits?
- Yes, water cooling is required, especially on glass and granite. It keeps the diamond grit from overheating and clears dust as you cut. Run your drill at a moderate speed, roughly 800 to 1500 RPM, and let the bit do the work.
- What hole sizes does this kit cover?
- Diameters range from 3 mm up to 100 mm, so you can cut small pilot holes or large openings for fixtures. The open crown design pushes out the core as you go. Each listing is a single piece, so pick the size you need.
