Milwaukee 2666-20 M18 Brushless 1/2″ High Torque Impact Wrench w/ Friction Ring

The Milwaukee 2666-20 M18 Impact Wrench gives professionals and DIY users cordless power for demanding fastening and removal tasks. Its 18V M18 platform and brushless motor suit work requiring a dependable high-torque tool. The 1/2-inch friction ring makes socket changes convenient, while the variable-speed trigger helps you adjust tool output to the task.

Milwaukee 2666-20 M18 Impact Wrench Features

Milwaukee rates this brushless impact wrench for up to 800 ft-lbs of fastening torque and 1,200 ft-lbs of nut-busting torque. These ratings make it useful for suitable lag-bolt driving, concrete-anchor installation, and loosening stubborn fasteners. Actual performance depends on the battery, fastener, material, and working conditions.

The motor delivers speeds from 0 to 1,750 RPM and up to 2,000 impacts per minute. A variable-speed trigger helps you start carefully and adjust speed as the fastener engages. This control can be useful when working across different materials or moving between installation and removal tasks. Always follow the fastener or equipment manufacturer’s torque specifications.

Convenient 1/2-Inch Friction Ring

The 1/2-inch square-drive anvil uses a friction ring to help you change compatible impact-rated sockets quickly, including with one hand. Choose sockets designed for impact tools and confirm that each socket matches the fastener and drive size. Do not use damaged or unsuitable accessories, and keep hands clear of the rotating anvil during operation.

An integrated LED light illuminates the immediate work area, helping improve visibility in garages, workshops, and dim jobsite corners. The cordless design avoids the need for an extension cord, while the M18 battery platform offers flexibility for users who already own compatible Milwaukee tools.

Brushless Motor and REDLINK Intelligence

The brushless motor is designed to provide power and long motor life. Milwaukee REDLINK Intelligence coordinates communication between the tool, battery, and charger to support performance and overload protection. Use a compatible Milwaukee M18 battery and charger, and follow the instructions for charging, storage, and inspection.

The 2666-20 is a tool-only model, so a battery and charger are generally sold separately. Check your listing for included accessories before ordering. This model is described as M18 Brushless, not M18 FUEL, so verify the model number when comparing similar Milwaukee impact wrenches.

For verified specifications, visit the official Milwaukee product page. Consult the official operator’s manual for operating instructions and safety warnings. You can also explore Milwaukee’s M18 battery and charger range to check compatible power options.

Suitable Applications and Safe Use

This impact wrench may suit builders, maintenance technicians, mechanics, and workshop users who regularly work with substantial fasteners. Use it only for appropriate applications and avoid assuming that maximum tool torque equals the required final tightening torque. For critical fasteners, follow the service procedure and finish with a calibrated torque wrench whenever specified.

Wear appropriate eye and hearing protection, secure the workpiece, and inspect sockets and the tool before use. Keep the work area clear, remove the battery before adjustments or accessory changes, and stop if the tool or battery shows damage. Follow the manual and all jobsite safety requirements.
