Hydro Handle HH12BIT 1/2 Inch Electroplated Diamond Bit 8 mm Shank

The Hydro Handle HH12BIT 1/2" Electroplated Diamond Bit is built for drilling precise 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 produces smooth holes while reducing chip-out on brittle surfaces. Engineered side holes improve cooling and clear slurry away 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. Designed with an 8 mm round shank, it fits universally in 3/8" and 1/2" drills for direct compatibility on the jobsite.
