The Milwaukee 2457-21 M12 3/8-Inch Cordless Ratchet Kit provides the speed and control of a power ratchet in a compact, lightweight form factor that fits into tight spaces. The kit includes the M12 ratchet, one compact battery, and a charger for a complete out-of-the-box solution. A variable speed trigger provides up to 250 RPM for fast fastening, while 35 ft-lbs of torque handles most automotive and mechanical fastening tasks. The ergonomic design reduces fatigue during extended use in confined workspaces.
