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 chiping when working delicate materials. HYDRO-HANDLE diamond drill bits are designed for use with all 3/8 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. ProductSiteLaunchDate : 2016-10-18T16:24:41.063Z SurfaceRecommendation : Glass UnitCount : 1
