The HT 20 mm Diamond Drill Bit is engineered for extreme performance and durability. Utilizing advanced vacuum brazing technology, this bit allows for fast, clean, and precise dry drilling through the hardest porcelain, ceramic, and natural stone tiles.

Key Features:

Vacuum Brazed Diamonds: High-quality industrial diamonds are bonded to the steel core at high temperatures, ensuring an aggressive cut and a much longer life compared to standard electroplated bits.
Fast Dry Drilling: Optimized for high-speed use (up to 11,000 RPM) without the need for water cooling. The internal cooling wax (in smaller sizes) or high-clearance design ensures effective heat management.
Clean Cut Performance: Designed to minimize chipping and prevent cracking in delicate materials, providing a professional-grade finish for plumbing or electrical installations.
5/8″-11 Thread: Fits directly onto standard North American angle grinders. The secure threaded connection ensures zero slippage and maximum torque.
Professional Versatility: Perfect for professional tilers working with hard porcelain tile, granite countertops, marble slabs, and engineered stone.
