The EXPERT MultiConstruction multi-purpose drill bit can accurately drill into hard materials such as granite without shrinking, thanks to its sharp tip, centering point and sophisticated geometry. It is made of optimised sintered carbide using a special fine grinding technique. Thanks to its 2 cutting edges and 4-spiral design, the Dura ensures efficient material removal when drilling. It can drill into concrete, masonry, ceramics, wood, plastic and sheet metal and always does a professional job - whatever the material. The clamping system consists of a cylindrical shank (CYL) suitable for standard drilling machines.
