Impaktor bit set contains the premium TriTorsion Bit Holder with optional Ringmagnet function to hold screws up to 10" long. Also contains Impaktor Diamond anti cam-out screwdriver bits. Stored in a slim & compact easy open case for tool security & easy bit selection. Specifically designed for cordless impact drivers, these bits are suited to the heaviest duty jobs. Diamond coated for anti cam-out, the patented Impaktor system is unrivalled in performance. The TriTorsion system means that together the bit and holder have three torsion zones to absorb the stresses applied by constant use in heavy duty impact drivers. Due to the precision hardening processes, the life of the screwdriver bits is dramatically increased.
