35mm M14 Gold Brazed Diamond Drill Bit

The 35mm M14 Gold Brazed Diamond Drill Bit is designed for high-speed dry drilling of large-diameter holes in hard tile and stone surfaces. Manufactured using gold brazed diamond technology, it delivers aggressive cutting performance and excellent durability, making it ideal for professional tilers and installers working with dense porcelain and natural stone.

Fitted with an M14 threaded connection, this drill bit mounts directly onto an angle grinder and operates efficiently at 6000–11000 RPM. Although designed for dry use, intermittent cooling by dipping the bit in water is strongly recommended to prolong tool life and maintain cutting efficiency.

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