WERA Driver Bit (Diamond Coated, Impact)

High quality bits for square socket screws. Impactor technology provides an above average service life even under extreme conditions. Coarse diamond grain coating on the bit tip increases friction resistance and prevents it from slipping out of the screw head. Particularly suitable for use with regular impact drivers. 1/4" hex, suitable for holders according to DIN ISO 1173-D 6.3. The diamond coating ensures a tight fit on the screw and literally bites into the screw head preventing cam-out. Color-coded tool finder according to profile and size.
