Product Description
Carbide Tip for Hard Materials: Each drill bit is tipped with YG6 grade tungsten carbide, offering a hardness of 89-91 HRA. This carbide formulation is specifically engineered for drilling through ceramic tiles, glass, porcelain, slate, and other hard, brittle materials where standard HSS bits fail to penetrate or wear out quickly.
Four-Flute Design for Faster Dust Removal: The four-flute spiral groove design enhances dust and debris evacuation during drilling, reducing heat buildup and preventing bit binding. This results in cleaner holes and longer bit life compared to traditional two-flute designs, especially in hard materials.
6.35mm Hex Shank for Universal Compatibility: The 6.35mm (1/4-inch) hex shank is compatible with most impact drivers, hammer drills, and quick-change chucks used by construction and renovation professionals. The hex shape prevents slipping in the chuck, ensuring positive torque transfer during demanding drilling applications.
Two Sizes for Versatile Applications: The set includes 6mm bits and 8mm bits, covering common anchor and fastener hole sizes for tile and masonry installations. The 6mm and 8mm diameters are ideal for wall plug anchors, screw anchors, and small plumbing or electrical penetrations.
Ideal for Tiling, Renovation, and Electrical Work: This drill bit set is an essential accessory for tilers, renovation contractors, electricians, plumbers, and HVAC technicians who regularly drill through tiles and masonry. Its durable carbide tips and efficient dust removal make it a practical stock item for hardware stores, tool distributors, and construction supply houses.
