This Bahco 7 piece Diamond Bit Set contains the following:
1 x Phillips 25mm bit: PH2.
1 x Pozi 25mm bit: PZ2.
4 x Torx 25mm bits: T15, T20, T25, T30.
1 x Universal bit holder, 1/4 inch drive.
The bits are made from high performance alloy steel. Their tips are coated with thousands of tiny, industrial grade diamond particles, providing high strength and good wear resistance. This also significantly reduces the 'cam-out' effect, to deliver the required torque to drive the screw.
Supplied in a handy plastic storage case.
