Hydro Handle HH34BIT 3/4 Inch Electroplated Diamond Bit 8 mm Shank

The Hydro Handle HH34BIT 3/4" Electroplated Diamond Bit is built for drilling accurate holes in tile, glass, porcelain, marble and other hard materials. This size is commonly used for shower valve openings, conduit penetrations and fixture mounts in tile and stone surfaces. 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 channel water to the cutting edge and remove slurry to improve cooling, while the lathed one-piece steel body resists stress and vibration under 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 jobsite compatibility.
