Product Summary

The Hydro Handle HH114BIT 1-1/4in. Electroplated Diamond Bit is designed for drilling precise holes in tile, glass, porcelain, marble and other hard materials. This size is commonly used for sink fittings, pipe penetrations and large hardware mounts in tile and stone installations. Its electroplated diamond coating provides a sharp and uniform cutting edge that delivers smooth holes while preventing 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 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 3/8in. and 1/2in. drills for direct jobsite compatibility.
