Part# 12-05883
MFR Model# 2466-20


Our M12 FUEL™ 1/2” Digital Torque Wrench w/ ONE-KEY™ is the industry's first torque wrench with a motor, delivering increased productivity, precise torque accuracy, and user demanded reporting functionality.

The 1/2” torque wrench delivers 50% faster installation time, replacing the hand tool or two tool installation process and providing more control to reduce the over torquing of fasteners. The 1/2” digital torque wrench provides 12.5-150ft-lbs of torque range and accuracy within 2% for torque critical fasteners.

This battery powered torque wrench is equipped with Milwaukee ONE-KEY™ giving you the power to track, report, and manage your tool. This tool will record all of the fasteners that are saved and produce a downloadable report via ONE-KEY™ for the necessary parties requiring the data.

ONE-KEY™ allows you to wirelessly connect to a smartphone to customize the tool settings, track its location, manage inventory, and lock the tool out for added security and protection for your investment.
