Wera 05073904001 840/1 IMP DC SB Impaktor bits, 4 x 25 mm

840/1 IMP DC SB Impaktor bits, 4 x 25 mm High quality Impaktor bits for hexagon socket screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Hex-Plus ensures a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. ¼" hexagon, suitable for holders as per DIN ISO 1173-D 6.3. 05073904001
