The NEO impact bits (ref. 09-587) are a set of 5 professional T30 impact bits with a length of 50 mm. They are designed for 1/4 ”screwdrivers. They have a system that protects them against slipping of the tip from the screw. The bits are made of S2 steel. They enable a high tightening torque of 21.8 Nm. The torque absorption system protects the tips against quick wear and significantly extends their service life.
