Bosch Maxgrip Phillips Screwdriver Bit PH1 25mm Pack of 3

It has a 1/4-inch external hex shank and is intended for universal screw-driving with screwdrivers and drill drivers. The Max Grip Screwdriver Bit offers an exceptionally firm grip when screw-driving. A micro-rough surface and titanium nitride coating prevent slippage out of the screw head and lead to better torque. This protects the screw and the surface against damage. The bit´s tapered torsion zone copes easily with torque peaks as it absorbs force and vibrations when screw-driving. Furthermore, the S2 Modified Steel and an optimised heat treatment process give the bit an extra-hard quality that enables an unwavering connection with screws.
