Hydro Handle HH38BIT 3/8 Inch Electroplated Diamond Bit 8 mm Shank

The Hydro Handle HH38BIT 3/8" Electroplated Diamond Bit is designed for drilling accurate holes in tile, glass, porcelain, marble and other hard materials. This bit is ideal for installing anchors, fittings and hardware where accuracy is critical. Its electroplated diamond coating provides a sharp and uniform cutting edge that delivers smooth holes while reducing chip-out on brittle surfaces. Engineered side holes improve cooling and remove slurry from the cutting edge, while the lathed one-piece steel body resists stress and vibration during high RPM use. The drill bit achieves maximum speed and life in water-feed setups while also providing dependable results in dry drilling when required. Built with an 8 mm round shank, it fits universally in 3/8" and 1/2" drills for direct compatibility on the jobsite.
