Screwdriver bits precisely machined on CNC machines have a torsion zone that absorbs torque loads. It guarantees optimal attachment flexibility and maximum durability in demanding applications. The 15-degree torsion zone allows the screw attachment to be bent instead of breaking. Longer service life, faster and more accurate screwdriving thanks to a special tool tip design that optimizes the placement of the tool in the mounting screws. Elimination of wobbling and slipping. Designed for professional users due to the maximum firm grip and no popping up when screwing. Excellent quality materials and optimized attachment design guarantee optimal flexibility, strength and extreme durability.
