Bosch 12 Piece Extra Hard Screwdriver Bit Set

The Bosch 12 Piece Extra Hard Screwdriver Bit Set is a screwdriver bit set designed for driving screws with drill drivers that deliver high torque. Standard bits can break under this load, so these bits are built to resist high torque and help you complete screwdriving jobs with confidence. The bits are made from heat-treated S2 modified steel for hardness and durability. Colour-coding and type and size markings let you pick out the bit you need quickly. The set is not suitable for use with impact drivers. Each bit has a hex shank for a strong connection and maximum torque transmission in three-jaw chucks and ¼" internal hex tool holders. The set covers Phillips, Pozidriv, Torx and slotted bits, and comes with a bit holder to keep everything together.
