HYDRO-HANDLE diamond drill bits are recommended for precise drilling of tile, glass, stained glass, granite, marble, onyx, quartz and other hard materials including precious and semi precious material such as garnet, amethyst, aquamarine, emerald and tanzanite.

HYDRO-HANDLE diamond drill bits are manufactured using lathed uni body design to resist fatigue cracks caused by tension, heat, pressure, RPM and vibration. Advanced metallurgical bonding procedures allow for a superior embedded layer of diamond substrate for longer wear life and finish consistency resulting in uniformed drilling profile and long life. Highly uniformed diamond bedding prevents chipping when working delicate materials.

HYDRO-HANDLE diamond drill bits are designed for use with all ? and 1/2 inch cordless drills as well as the HYDRO-HANDLE diamond drilling system. A liquid coolant such as water is required when drilling with HYDRO-HANDLE diamond drill bits.

Use the included bit guide to accurately position the diamond drill bits while drilling. The guide provides additional water deliver (when used with cordless drill) and removal (when used with the HYDRO-HANDLE) capabilities.
