851/1 ADC bits, aviation
High quality bits for Phillips screws. The diamond coating of the bits ensures a secure fit in the screw, reduces the contact pressure required and lowers the risk of slipping. Profiled version with especially sharp edges which break away the paint when e.g. screw profiles are covered in it and this ensures a dependable transfer of power between the bit and screw. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
