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 a good fit in the screw. The set contains PZ: 1, 2, 2, 3 and Torx® T10, 15, 20, 25, 30 and 40, which is a combination that is suitable for multiple areas of application. The belt clip allows the user to keep both hands free for work, while at the same time having direct access to the bits.
