Bitflex bits: the damping zone (only for 25 mm long bits) between the drive and the working tip absorbs excess force peaks that previously led to high wear and destructive ejection forces. The FLEX zone gives the Bitflex a significantly longer service life than conventional standard bits. All bits with 1/4 hexagon drive, length 25 mm, TIN, which is the short form for titanium nitride. This special coating brings an additional improvement in service life to the already excellent values of the Bitflex. Single bits for Phillips PH2 cross-head screws, length 10 mm.
