Product description
- Screwdriving bits made from chrome vanadium steel (S2 quality) for high durabily and forced closure with the screws
- Special diamond coating for extremely safe fit in the screw. Reduction of the "come out" effect, thus significantly reduced workload
- The torsion zone permits to equalise torque peaks, since it absorbs forces and vibrations during the screwdriving process. High force load possible; prevents from premature breakage.
- 1/4" hex drive
