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 drive train and hammer mechanism are designed to provide technicians the power they need without adding extra weight to the tool. CONTROL: With 4 power modes (MAX Power, Half Power, Wrench Tight, and Hand Tight), 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, there’s no need to switch tools. The variable-speed switch with electronic brake provides MAX control of the tool and increases safety-release trigger, drive stops spinning. DURABLE: Protected by a chemical-resistant composite housing and a patented steel-reinforced frame, the W5153P-C1D2 is built to withstand repeated drops onto concrete and exposure to shop fluids. The IQV spark-free brushless technology and sealed, enhanced, lubricated reinforced bushing provide a longer-life motor you can rely on. ACCESS: Thanks to its 6.5” tip-to-tail compact ergonomic design and lightweight build, the W5133P-C1D2 can easily access tight spaces, giving you access no matter where your work may be hiding. A built-in 360 degree LED light ring with task light mode and 4 dimmable settings casts a wide beam to give you excellent visibility with no shadows.
