Bosch 19 Piece L Extra Hard Screwdriver Bit Set

The Bosch 19 Piece L-BOXX Extra Hard Screwdriver Bit Set is a comprehensive mixed bit set designed for professional and trade use, covering the most common drive types encountered on site.

Built from S2 modified steel with an optimised heat treatment process, each bit delivers extra-hard performance suited to demanding screwdriving applications. The set includes Phillips (PH1, PH2, PH3), Pozi (PZ1, PZ2, PZ3), and Torx (T8 through T40) bits, providing excellent coverage across a wide range of fixings and fasteners.

Each bit features a tapered torsion zone that absorbs torque peaks, force, and vibration during use, reducing the risk of bit damage and improving longevity. The 1/4-inch external hex shank ensures a secure connection and maximum torque transmission, making these bits compatible with both three-jaw chucks and 1/4-inch internal hex tool holders on screwdrivers and drill drivers.

Ideal for carpenters, electricians, and general contractors who need a reliable everyday bit set, the included quick-change universal holder further adds convenience when switching between bit types on the job.
