High-precision drilling of multiple materials - This extremely versatile drill bit allows precise drilling in hard materials such as granite without slipping. This is made possible by its sharp point and advanced geometric design. It has been manufactured from optimised carbide using our fine grinding manufacturing process and is therefore equally suitable for concrete, brick, soft ceramics, wood and metal. Regardless of the material, it always performs professionally. Hexagonal shank for a strong connection and maximum torque transmission in three-jaw chucks and 1/4-inch hexagon socket tool holders.
