Carbide drill bits for drilling on glass, wood, metal and ceramic tiles. - Versatile sizes: available in 6 mm and 8 mm. Each bit is 90 mm long with a 35 mm grip (1/4 inch). The size is clearly marked for quick selection. - Durable and high performance: made from carbide material for wear resistance and long life. High hardness supports efficient, precise drilling across different surfaces. - Easy to use: clearly labeled size, comfortable 35 mm grip, compatible with standard drills. - Dry or wet drilling: suitable for both dry and wet drilling. Using water during the process can reduce heat and extend bit life. Practical use scenarios - Install glass or ceramic tile fixtures by drilling clean, accurate holes for anchors. - Create pilot holes in wood furniture or cabinets, or in metal panels for screws and hardware. - Prepare holes in thin metal sheets or other hard materials where precision is required.
