Stop Fighting Ordinary Drill Bits
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.
Why It Belongs in Your Toolbox
Built for Cleaner, More Confident Drilling
01
Cleaner Hole Edges
The diamond cutting surface helps create smoother, more controlled holes while reducing unnecessary edge chipping.
02
Vacuum-Brazed Cutting Surface
High-density diamond particles provide dependable cutting performance across demanding hard materials.
03
Convenient Dry Drilling
Designed for dry-drilling convenience without requiring a constant water supply during normal use.
04
Faster Chip Removal
The hollow cutting structure helps debris escape more easily for smoother and more efficient progress.
05
Six Practical Sizes

06
Secure Hex Shank
The 1/4-inch hexagonal shank provides a stable grip and works with many commonly used drilling tools.
More Convenient Installation
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.
Professional Cutting Construction
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.
Easy Tool Compatibility
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.
Important: Do not use hammer or impact mode when drilling tile, glass, ceramic or natural stone.
One Set, Multiple Surfaces

Simple Two-Step Technique
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.
For Better Drilling Results
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.
