Our take on the Milwaukee 2966-20 M18 FUEL 1/2" High Torque Impact Wrench w/ Pin Detent

The Milwaukee 2966-20 is a cordless 1/2-inch high-torque impact wrench built on the M18 FUEL platform. Its brushless motor delivers up to 900 ft-lbs of fastening torque and 1,100 ft-lbs of nut-busting torque, and the tool is 7.3 inches long for access in tight spaces. A pin detent locks sockets in place, which suits overhead and heavy-equipment work. Four drive modes, including a bolt-removal mode and an auto-shutoff that caps torque at 50 ft-lbs, give it more control than single-speed rivals. It is a bare tool, so batteries and a charger are bought separately. Owners rate it for power and durability; the main trade-offs are its weight and the pin detent, which holds sockets firmly but makes swaps slower than a friction ring.

About the Milwaukee 2966-20 M18 FUEL 1/2" High Torque Impact Wrench w/ Pin Detent

The Milwaukee M18 FUEL 1/2" High Torque Impact Wrench has a POWERSTATE brushless motor that delivers up to 900 ft-lbs of fastening torque and 1,100 ft-lbs of nut-busting torque. At 7.3" long, it fits into tight spaces. The housing is glass-filled nylon.

A 4-Mode DRIVE CONTROL lets you choose output speed and power with one button on the tool. Mode 4 includes auto shut-off, which applies no more than 50 ft-lbs of torque to prevent overtightening. It also includes bolt-removal mode, which gives full torque to break a fastener free and then slows to 750 RPM for more control.

The 1/2" pin detent anvil locks sockets in place, including during overhead work. Three LEDs light the workspace with fewer shadows. A patented battery isolation system keeps the battery connection secure and limits vibration passed to the pack. REDLINK PLUS Intelligence protects against overloads, heating and over-discharge. A lanyard loop is included.

Questions and answers

Is the 2966-20 worth it over the previous high-torque model?
It adds more nut-busting torque, a shorter body and a four-mode drive control with auto-shutoff. If you already own the older model and it handles your work, the gain is mainly in control and access.
Does it come with a battery and charger?
No. It is a bare tool and includes the wrench and a lanyard loop. You need M18 batteries and a charger, ideally high-capacity packs for full torque.
What is the difference between pin detent and friction ring?
A pin detent locks the socket with a pin, so it stays on during overhead work. A friction ring holds by friction and is faster to change but can drop sockets.
How much torque does it make?
Up to 900 ft-lbs of fastening torque and 1,100 ft-lbs of nut-busting torque. Auto-shutoff mode limits output to about 50 ft-lbs for small fasteners.
What size sockets does it take?
It uses 1/2-inch drive impact sockets. Use impact-rated sockets, not chrome hand sockets, for high-torque work.
Can it remove lug nuts on a truck?
Yes, its nut-busting torque handles most passenger and light truck lug nuts. Very tight or rusted fasteners may still need a breaker bar or heat.
