7mm M14 Gold Brazed Diamond Drill Bit
Professional 7mm M14 gold brazed diamond drill bit for fast, dry drilling of porcelain, marble, granite, and travertine tiles using an angle grinder.
The 7mm M14 Gold Brazed Diamond Drill Bit is designed for high-speed, dry drilling in hard tile and stone surfaces. Manufactured using gold brazed diamond technology, this drill bit delivers aggressive cutting performance, making it ideal for professional installers working with hard porcelain and natural stone.
Fitted with an M14 threaded connection, it mounts directly onto an angle grinder and operates at high speeds of 6000–11000 RPM, allowing rapid penetration through dense materials. While designed for dry use, periodic cooling by dipping the drill bit in water is 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.
