Versatile diamond drill bit set for clean, precise holes.
This 15-piece Diamond Drill Bit Hole Saw Set is designed for accurate, chip-reduced drilling in tile, marble, glass, porcelain and ceramic. Each bit features a diamond-coated cutting edge for efficient material removal and a smooth finish, while the steel body provides strength and consistent performance with standard electric drills.
The set includes commonly used sizes from 6 mm to 50 mm, giving you flexibility for a wide range of tasks such as installing fixtures, routing cables, or creating openings in decorative glass and tiles. When used with adequate cooling (water) and steady pressure, these bits help reduce cracking and edge damage, resulting in cleaner, more professional-looking holes for both DIY and trade projects.

FAQ
Q: Which materials can I drill with this set?
A: These bits are suitable for ceramic tile, porcelain, glass, marble and similar brittle, non-ferrous materials. They are not intended for wood or metal.
Q: Do I need to use water while drilling?
A: Yes. Using water as a coolant helps extend bit life, reduce heat buildup and minimize the risk of cracking the material.
Q: Can I use these bits with a hammer drill setting?
A: No. Use the rotary (non-hammer) mode only. Hammer action can damage both the bit and the work surface.
Q: Will these bits fit my regular household drill?
A: In most cases, yes. The shanks are designed for standard drill chucks commonly found on corded and cordless household drills.
