A 45-piece magnetic bit set with S2 steel bits, CR-V sockets, and an extension rod in a transparent case
This 45-piece screwdriver bit set supplies slotted, Phillips, square, Torx, two hex nut sockets and an extension rod in a transparent storage case. It suits technicians and DIY users who need a broad range of drive types for everyday fastening tasks. The bits are made from high-strength S2 alloy steel with a phosphate blackened finish. CR-V sockets and a composite extension rod complete the kit.
The bits are manufactured from S2 steel, a high-strength alloy chosen for hardness and wear resistance on demanding jobs. This material grade is the single specification that determines whether the set meets professional durability requirements. A phosphate blackened coating adds corrosion protection across all bits and sockets. The extension rod combines a CR-V hex shank, aluminium core, carbon steel tube and heat-shrink sleeve.
A built-in magnet holds screws securely for precise alignment during installation and removal. The transparent PC and ABS case measures 159 x 96 x 44 mm and weighs 0.452 kg, keeping the kit light and easy to store. No moving parts or powered components mean silent operation and zero power draw. The blackened finish resists rust during long-term workshop use.

The set supplies slotted, Phillips, square and Torx bits plus two hex nut sockets and an extension rod, with duplicate sizes for the most common fasteners so you can keep driving without hunting for a spare.
The 1/4-inch hex shank fits standard drill chucks and quick-change holders, capping the maximum torque to what a typical cordless drill or impact driver can deliver without rounding the shank.
The case measures 159 mm long, 96 mm wide and 44 mm deep, so it slides into most medium tool pouches or sits flat on a shelf without wasting space.
