Ergonomic Design: The 39-piece ratcheting screwdriver features a detachable handle and an ergonomic, flex-angle design that cuts wrist fatigue by 80%, making it easy to work in tight spots for extended periods. Alloy-Steel Bits: Thirty-eight S2 alloy-steel bits (Phillips, slotted, Torx, Hex) deliver high strength and shock resistance for screws of any hardness. Magnetic Assist: A strong magnetic handle holds bits securely, prevents drops and allows one-handed, quick-change operation. Extended Power Grip: The electric-style grip is long enough for two-handed use, giving extra torque and stability on stubborn or deeply recessed screws. 3-Position Ratchet: Clockwise, counter-clockwise and locked—change modes instantly with a flick of the thumb. Detachable handle converts to stubby or T-handle for the most efficient grip in any situation., Manufacturer: LuLobtg
