PWRCore 20 Icon


The SKIL PWRCORE 20™ Brushless 20V 3/8-inch Compact Impact Wrench gives you big power in a compact, lightweight package with up to 170 foot-pounds of fastening torque, 220 foot-pounds of nut-busting torque, and up to 3,950 IPM for driving tough nuts and bolts. At more than 1 inch shorter than its previous generation, this cordless impact wrench is an ideal power tool for working overhead or busting hard-to-reach car lug nuts and caliper bolts. Its 3/8-inch square anvil features a friction ring for easy socket changes, and its digital brushless motor combined with three-speed selection provides high-performance power and precise control. Its Halo Light™ provides 5X more light than common LEDs while reducing shadows—and it lights up your workspace for up to 10 minutes.
