Hydro Handle HHBLKIT Diamond Tile Hole Saw Drill Bit Set, Glass, Stone Concrete Tile Saw

The Hydro Handle HHBLKIT Large 10-Piece Electroplated Diamond Bit Kit provides a full range of bit sizes for drilling tile, glass, stained glass, granite, marble, onyx, quartz and other hard materials. This set includes 1/4", 5/16", 3/8", 1/2", 3/4", 1", 1-1/4", 1-3/8", 1-1/2" and 2" bits, making it ideal for pipe penetrations, faucet holes, shower valves and fixture installations. Each bit features an electroplated diamond coating that delivers a sharp and uniform cutting edge for smooth holes while preventing chip-out on brittle surfaces. Engineered side holes channel water to the cutting edge and flush slurry away to improve cooling, while lathed one-piece steel bodies resist stress and vibration during high RPM drilling. The drill bits achieve maximum speed and life in water-feed setups while also providing dependable results in dry drilling when required. Organized in a durable storage case with a clamp-style drill guide, this kit ensures accuracy, convenience and better value compared to buying bits individually.
