GRAFF bit PZ2x100 mm is a special tip for a screwdriver or drill equipped with cam or collet chucks. It has a universal shank. A bit is made of a special hard alloy with a tip hardened. Hardness is 60 HRC. Thanks to its elongated shape working with such a bit is convenient in places where it is impossible to use a standard shortened bit e.g. when assembling or disassembling appliances. The cruciform shank is equipped with additional ribs between the main ones, thanks to which it is possible to twist the bit at a small angle. It is designed to work with self-tapping screws that have the appropriate shape of caps.
