Description

The Venom Green Blind-Hole Non-Coring Anchor Bits are engineered for precision flat-bottom anchor drilling in quartz, quartzite, granite, marble, and natural stone. These bits combine a metal-bond diamond coring section with vacuum-brazed side-protection diamonds, delivering a stable, fast-cutting, and durable blind-hole solution for professional stone fabrication.

The metal-bond diamond tip grinds a clean, controlled flat-bottom hole without producing a core plug. This makes it ideal for mounting hardware, brackets, clips, pins, reinforcement anchors, and structural fittings.

The vacuum-brazed diamond side protection enhances stability by preventing binding, reducing sidewall chipping, and allowing the bit to lightly shape or widen a hole without damage to the stone. This hybrid construction gives fabricators the ideal balance of speed, control, and long tool life.

Designed for wet or dry drilling, the Venom Green series performs reliably both in the shop and on job sites. The 5/8-11 universal thread fits standard grinders and polishers used throughout the stone industry.
