The Mac Tools 52-pc 4V Cordless Screwdriver Set has a compact design that mirrors that of a traditional multi-bit screwdriver, with a 300 rpm motor, maximizing speed while minimizing strain. The IP54 rating and durable handle material protects against water, dust, and various solvents, while an internal locking mechanism stabilizes gearing when manual torquing is required. The five-bulb LED illumination enhances work surface visibility, while the three-stage charge indicator updates the battery status. Simple push-button functionality makes driving/reversing screws easy, with a quick-change collet for no-hassle bit swap-out and secure hold. The tool delivers a full recharge in 70 minutes and up to 1,300 screws per charge.
