Bit set with 10 torsion diamond bits and 1 magnetic bit holder 1/4". The optimized torsion zone absorbs impact power to reduce bit tip stress and extend the service life. Diamond grip tips prevents the bit to slip out of the screw head and secures fit in the screw. The set contains PH 1: 2, 3. PZ: 1, 2, 3 and Torx®: 15, 20, 25 and 30, which is a combination that is suitable for multiple areas of application.
