Product Description
Two Drill Bit Types for Complete Tile Drilling: This set combines a 6mm triangle carbide tip drill bit for precise, slip-free starting on glazed surfaces, and five diamond drill bits (5-12mm) for clean hole cutting through ceramic tiles, glass, marble, and porcelain. The triangle bit creates an initial indentation to prevent wandering, while the diamond bits complete the hole with minimal chipping.
Diamond Bits with Built-In Cooling Wax: The five diamond drill bits are manufactured using a vacuum sintering process, with diamond grit embedded in the cutting edge. Each bit contains built-in cooling wax that melts during drilling, reducing friction and heat buildup, extending bit life, and preventing thermal cracks in the workpiece.
Triangle Carbide Bit for Precise Starting: The 6mm triangle bit features a YG6 grade tungsten carbide tip (89-91 HRA) on a 40Cr steel shank with a nickel-plated finish. Its triangular shape provides exceptional grip on smooth tile surfaces, allowing the user to establish a pilot hole without the bit slipping or skidding across the glaze.
Universal 6.35mm Hex Shank: All six bits feature a 6.35mm (1/4-inch) hex shank, compatible with impact drivers, hammer drills, and quick-change chucks commonly used by tilers and renovation professionals. The hex design prevents spinning in the chuck, ensuring positive torque transfer during demanding drilling tasks.
Comprehensive Size Range for Common Applications: The diamond bits cover diameters from 5mm to 12mm (5,6,8,10,12mm), suitable for wall plug anchors, pipe penetrations, cable pass-throughs, and small fixture mounts. The set includes working lengths of 42mm for all diamond bits, with overall lengths ranging from 65mm to 80mm. It is an essential kit for tile installers, bathroom fitters, electricians, plumbers, and general renovation contractors.
