Wera Kraftform Kompakt 100

52 pieces; in a surface-friendly, compact textile box with a high degree of robustness. Low volume and weight provide easier mobility. Compact tool set with 52 screwdriver pieces. 1 Rapidaptor bit holder with quick-change; 1 Rapidaptor bit holder for placement in the screwdriver or for use in the chuck of an electronic drill; 30 BiTorsion bits with a length of 25 mm for long life, hard and durable (BTZ), for universal use, extra hard (BTH), 12 Impaktor bits with a length of 50 mm for particularly high demands, 8 angle wrenches with Hex-Plus profile (prevents rounding off screws with internal hexagon) and hexagonal ball head on the long arm for work at an angle; very robust textile box with long life span; can be placed upright to facilitate storage on workshop shelves; additional surface protection through textile covering.Impaktor bits are necessary when using a powerful screwdriver. Impaktor bits are specially developed to withstand large machine forces.BTZ bits have a BiTorsion zone where the shaft hardness is reduced by about 20% compared to the starting point. This avoids twisting of the bit tip under maximum load in most cases, which further extends its lifespan.Wera Rapidaptor: The holder accommodates all standard-sized quarter-inch bits without having to operate any bushings or locks itself securely into place. The smallest sizes can also be easily removed by sliding forward on their own bushing during operation so that battery- or electric-powered screwdrivers can be safely stabilized while driving screws thanks to its free-running design - all functions can be performed single-handedly! No faster way exists than changing out your driver tips!Screws featuring hexagonal grooves have an issue where they quickly become "rounded off." This is due to sharp edges from tools affecting internal surfaces within their heads over time. The wear process gradually leads to the groove becoming "rounded off." Wera Hex-Plus tools have larger contact surfaces in the screw head. This reduces the effect of grooves and thus deformation of screws. At the same time, up to 20% greater torques can be transmitted.
