Description

DIAMANT-TECH 2026: The new benchmark for professional drilling in tiles and natural stone.

Forget slow drilling progress and chipped edges. The next-generation XIIW M14 diamond hole saws deliver maximum precision and speed thanks to the advanced Cu-Sn-Ti alloy - even in the hardest porcelain stoneware.


Why the 2026 generation of XIIW makes the difference:

  • 40% Higher Speed: Drill through the hardest material in just 8–16 seconds per hole - save valuable time on the job site.
  • Monocrystalline Diamonds: Uses high-strength synthetic monocrystals for 3x longer durability compared with standard drill bits.
  • No Cooling Required: Optimized for dry drilling with heat resistance up to 1000°C - flexible and efficient without a water supply.
  • Precision Without Chipping: The 40/50 mesh grit ensures smooth edges and protects even delicate surfaces.
  • Universal Compatibility: Standard M14 thread for all common angle grinders (max. 11,000 rpm).

Technical Specifications:

Technology Vacuum-brazed Cu-Sn-Ti monocrystalline diamond
Hardness Greater than HV 10,000
Working Depth / Length 40 mm / 60 mm
Speed (Recommended) max. 11,000 rpm

Frequently Asked Questions (FAQ):

1. Can I really drill completely dry?
Yes, the 2026 series is specially designed for dry drilling. However, for extremely hard materials, occasionally dipping it in water can extend the service life even further.

2. Why do professionals start at a slight angle?
By starting at an angle (approx. 45°), the diamond core bit bites in better and prevents slipping on the smooth tile surface.

XIIW Pro Tip: Use moderate pressure and a slight pendulum motion for optimal results and maximum service life.
