40pcs. bit set

This professional 40-piece bit set is a versatile and reliable solution for every automotive and mechanical workshop. The set provides comprehensive coverage of the most common fasteners encountered in modern vehicles, machinery, and equipment.

The set includes bits in two lengths (30 mm and 75 mm), which significantly increases reach and capability, allowing access to deeper-seated screws and bolts. All bits are made from high-quality Chrome Vanadium Steel (CR-V) and benefit from forging technology, ensuring exceptional strength. The optimized hardness (48-52 HRC for bits) guarantees a long service life and high resistance to wear and deformation.

The kit covers a full range of popular bit types: Hex, TORX, and XZN (Spline). The included 1/2" and 3/8" adapters allow for immediate use with most standard socket wrenches and ratchets. The entire set comes in a practical, durable storage case.
