The wera 52 piece kraftform kompakt 100 screwdriver service bit set is a comprehensive screwdriving kit designed for tradespeople and technicians who need a versatile, portable solution for professional fastening tasks. At the heart of the set are two rapidaptor bit holders one standard and one compatible with power screwdrivers and drill chucks allowing fast, tool-free bit changes on the job. The 30 bitorsion bits 25 mm offer excellent durability through shock-absorbing and extra-hard variants, while the 12 impaktor bits 50 mm are engineered to handle the high-torque demands of impact drivers and demanding applications.
