POWER:†The brushless motor and impact mechanism are finely tuned to unleash a high power-to-weight ratio, with 550 ft.-lbs. of nut busting torque and 365 ft.-lbs. of MAX torque at 5.3 lbs (with BL2022 battery).. The all-metal drivetrain and hammer mechanism are designed to provide technicians the power they need without adding extra weight to the tool. CONTROL:†With 4 power modes, you can adjust a dial instead of changing tools to deliver the right amount of torque when you need it and eliminate rework. From brake calipers to valve covers and everything in between, thereís no need to switch tools. The variable-speed switch with electronic brake provides MAX control of the tool. DURABLE: Protected by a chemical-resistant composite housing and a patented steel-reinforced frame, the W5133 is built to withstand repeated drops onto concrete and exposure to shop fluids. The IQv spark-free brushless technology and reinforced bushing provide a longer-life motor you can rely on. ACCESS:†Thanks to its compact ergonomic design and lightweight build, the W5133 can easily access tight spaces, giving you access no matter where your work may be hiding. A built-in 360 degree COB LED light casts a wide beam to give you excellent visibility with no shadows.
