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. Coverage across fastener types is extensive, with Phillips, Pozidrive, TORX®, slotted, and hex profiles included. The set also features eight chrome-plated L-keys with Hex-Plus profile geometry, which helps prevent rounding of hexagon socket screws — ideal for assembly, service, and maintenance work across a wide range of trades. The entire kit is housed in a compact, surface-protecting textile case that can stand upright for organised workshop storage, while its low volume and weight make it practical to carry on site. A hook-and-loop fastener strip is also included.
