Clean, Precise Holes in
Hard Surfaces
Drill through tile, glass, granite, marble and other hard materials with greater control, cleaner edges and less frustrating bit slippage.

Diamond Edge
Drilling
Sizes
Shank
Hard Surfaces Should Not Mean Rough Results
Standard drill bits can slide across smooth tile, struggle to cut hard stone and leave cracked or uneven edges. These diamond drill bits are designed to create a more stable starting groove and a cleaner, controlled opening.

Built for Cleaner, More Confident Drilling
Cleaner Hole Edges
The diamond cutting surface helps create smoother, more controlled holes while reducing unnecessary edge chipping.
Vacuum-Brazed Cutting Surface
High-density diamond particles provide dependable cutting performance across demanding hard materials.
Convenient Dry Drilling
Designed for dry-drilling convenience without requiring a constant water supply during normal use.
Faster Chip Removal
The hollow cutting structure helps debris escape more easily for smoother and more efficient progress.
Six Practical Sizes
Choose the right diameter for wall anchors, pipes, cables, faucets, shower fittings and home accessories.
Secure Hex Shank
The 1/4-inch hexagonal shank provides a stable grip and works with many commonly used drilling tools.
Dry Drilling Made Easier
Complete common tile and stone installation projects without setting up a continuous water feed. Use light pressure and pause periodically during longer drilling sessions to control heat.

Premium Materials, Built to Perform
Every part is designed to support more stable drilling—from the diamond-coated cutting edge to the anti-slip hexagonal shank.

Works With Common Drilling Equipment
The secure hex shank can be used with standard hand drills, cordless drills and suitable bench drills, giving you more flexibility for workshop and on-site projects.

Built for Tough Materials
Ideal for bathroom renovations, kitchen installations, plumbing work, cable routing, wall accessories, DIY repairs and professional construction projects.
Start at 45°. Finish at 90°.
Begin at an angle to create a stable starting groove. Then slowly bring the drill upright and use a gentle circular motion to finish the hole and clear debris.

Let the Diamond Edge Do the Work
- Begin with the drill positioned at approximately a 45-degree angle.
- Use light, controlled pressure instead of forcing the drill downward.
- Slowly move the drill into a 90-degree upright position.
- Gently rock the bit in a small circular motion to help remove debris.
- Pause periodically during extended drilling to reduce excess heat.
- Always wear suitable eye protection and safety equipment.

Frequently Asked Questions
Can these bits be used without water?
They are designed for convenient dry drilling. During longer drilling sessions, periodically pausing or cooling the bit can help control heat and support longer service life.
Will these bits work on porcelain and ceramic tile?
Yes. They are designed for hard materials including porcelain tile, ceramic tile, glass, granite, marble, quartz and other suitable stone or masonry surfaces.
Should I use hammer mode?
No. Use standard rotary drilling mode. Hammer or impact mode may damage the material, the drill bit or both.
How do I keep the bit from slipping?
Begin drilling at approximately a 45-degree angle using light pressure until a starting groove forms. Then slowly bring the drill into an upright position.
What projects are these suitable for?
They are suitable for installing bathroom fixtures, kitchen accessories, anchors, pipes, cables, faucets, shower fittings and other home renovation or professional construction components.
