This 10-pack covers common drilling needs with sizes 3/16 in. (5 mm), 1/4 in. (6 mm), 5/16 in. (8 mm), and 3/8 in. (10 mm). The set includes multiple drill bits and PH2 driver bits, enabling work on glass, tile, and ceramic materials. An integrated heat resistant wax lubrication system reduces friction on delicate surfaces, helping to minimize chipping and eliminating the mess of water cooling during operation. The wax system supports cleaner debris removal and smoother progress, while contributing to longer tool life under repetitive use. The vacuum brazed diamond coating employs a thickened, reinforced layer secured by brazing methods to maintain grit integrity and provide stable performance when drilling through hard materials. The anti-corrosion surface and diamond grit are designed to sustain consistent performance, delivering smooth, precise cuts and efficient drilling across tile and stone projects. The tip features increased diamond exposure, which enhances cutting speed and reduces the effort required to breach materials. The round shank design broadens compatibility with a wide range of power drills and bench drills, adding practical flexibility for various workshop setups and tasks. In sum, the combination of varied sizes, lubrication, durable construction, and compatible shank design supports efficient, controlled drilling on glass, tile, and ceramic surfaces when tackling home improvement projects.
