High quality Wera Micro screwdriver set for precision mechanical work. Ballpoint profile: the ballpoint drive profile means that it is possible to swivel the tool axis away from the screwdriving axis, thus enabling "round the corner" screwdriving. Rapid twisting is possible by fixing the hand on the twist cap and using the fast-turning zone just below it. This makes time-consuming grip adjustments unnecessary. Power zone with integrated soft zones ensure the transfer of higher tightening and loosening torque. Precision zone for the right angle for adjustment work. The Wera Black Point tip offers high corrosion protection and an exact fit.
