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. The Compact set offers easy access to the contents and can be unobtrusively stored in a pocket when not in use. It has a 1/4-inch external hex shank and is intended for universal screw-driving with screwdrivers and drill drivers. 11+1-piece screwdriver bit set Max Grip version Bits length 25 mm ISO 1173 C6.3 with magnetic universal holder • Distinctly Firm Grip • The max Grip Screwdriver Bit has an exceptionally firm grip when screw-driving • The micro-rough surface and titanium nitride coating give high power transmission and protection against damage • The tapered torsion zone copes easily with torque peaks absorbing force and vibrations • S2 Modified Steel and an optimised heat treatment process for extra-hard quality and unwavering connection with screws Specifications: Set contents: (#227055 – 8678; PH1 PH2 PH3)(#227054 – 8682; PZ1 PZ2 PZ3)(#227052 – 8687; T10 T15 T20 T25 T30) Length mm: 25
