The enhanced friction resistance from the rough diamond-particle coating on the tip of the bit prevents any slipping out of the screw head. Particularly suitable for use with customary impact drivers; 1/4" hex, appropriate for holders as per DIN ISO 1173-D 6.3. Come with "Take it easy" Toolfinder: colour coding according to profile and size stamp.
