Key benefits - Reduces effort and wrist movement: 6.2° ratchet design with a 58-tooth forward/reverse mechanism saves up to 80% of the labor required for repetitive tightening/loosening. Torque rating 50 N·m (50 kg), so less force and no frequent wrist repositioning. - One set for many jobs: 40 precision S2 chrome-molybdenum alloy bits (magnetic) in a standard 6.35 mm (1/4") diameter fit most common fasteners and accessories. - Built to last and reach tight spaces: detachable aluminum-alloy handle is hot-forged, CNC-formed, oxidation-resistant and designed for use in narrow or awkward locations. What’s included - 40 bits total, S2 magnetic chrome-molybdenum alloy steel, 6.35 mm (1/4") shank: - Phillips (PH): 4 pieces - Slotted (SL): 4 pieces - Torx: 10 pieces - Hex: 9 pieces - Pozidriv (PZ): 3 pieces - U-type: 2 pieces - Plus 8 long bits, 45 mm for deep or recessed fasteners Key features - Ratchet mechanism: 6.2-degree increment and 58-tooth construction for fine engagement, reliable forward/reverse action. - High torque capacity: rated up to 50 N·m / 50 kg for demanding fastening tasks. - Handle design: detachable T-handle made from super-hard hot-forged aluminum alloy with high-precision CNC one-piece molding—durable, wear- and oxidation-resistant. - Multi-function T-handle: convertible configuration to switch between inline screwdriver, T-handle for leverage, or compact ratchet for tight spots. - Magnetic bits: retain screws for faster single-handed operation and reduce dropped fasteners. - Standard compatibility: 6.35 mm (1/4") bit diameter fits standard sockets, holders and accessories. Practical applications (real-world scenarios) - Electronics and appliance repair: use the precision S2 bits and magnetic tip to remove and replace small screws in household appliances or consumer electronics without losing fasteners. - Furniture and assembly work: high torque and Torx/Hex options handle assembly/disassembly of flat-pack furniture, fixtures and larger fasteners while the long 45 mm bits reach recessed screws. - Automotive and bicycle maintenance: ratchet action and T-handle leverage let you tighten or loosen bolts in tight engine bays or around frame components without repeatedly adjusting wrist position. Why this set solves common problems - Saves time and reduces fatigue for repetitive fastening tasks with a high-tooth-count ratchet and small engagement angle. - One durable handle plus a wide assortment of professional-grade bits eliminates the need to carry multiple screwdrivers. - Detachable, convertible handle and long bits provide access to confined spaces and recessed screws that stubby or fixed drivers cannot reach.
