Bosch 12 Piece Extra Hard Screwdriver Bit Set

The Bosch 12 Piece Extra Hard Screwdriver Bit Set is a 25 mm screwdriver bit set designed for high-torque screwdriving with drill drivers. Modern drill drivers deliver high torque that often breaks standard screwdriver bits. These Extra Hard bits are made from heat-treated S2 modified steel for hardness and durability, so they resist that torque and help you finish screwdriving jobs with confidence. The set covers Phillips, Pozidriv, Torx, slotted and hex drive types in one bit holder. Colour-coding and type and size markings help you pick out the right bit quickly. The hex shank gives a strong connection in three-jaw chucks and ¼" internal hex tool holders. Please note these bits are not suitable for use with impact drivers.
