8mm M14 Gold Brazed Diamond Drill Bit

The 8mm M14 Gold Brazed Diamond Drill Bit is engineered for high-speed dry drilling in hard tile and stone surfaces. Manufactured using gold brazed diamond technology, it delivers aggressive cutting performance, making it ideal for professional installers working with dense porcelain and natural stone.

Equipped with an M14 threaded connection, this drill bit mounts directly onto an angle grinder and operates efficiently at speeds of 6000–11000 RPM. While designed for dry use, periodic cooling by dipping the bit in water is recommended to prolong tool life and maintain optimal cutting performance.

An optional adaptor is available to convert the M14 thread for use with standard 3-jaw drill chucks, offering flexibility across different tools on site.
