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

The Hydro Handle HHBSKIT Small 10-Piece Electroplated Diamond Bit Kit is designed for precision drilling in tile, glass, stained glass, granite, marble, onyx, quartz and other hard materials. This set includes two 1/4", two 1/4" (6.5 mm), two 5/16", two 3/8" and two 1/2" bits, making it ideal for anchors, fasteners and small fitting 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 compact storage case with a clamp-style drill guide, this kit ensures accuracy, portability and value compared to purchasing bits individually.
