Overview
A shop with trucks, trailers or large equipment is where this Milwaukee wrench belongs. It has a ratcheting socket end, a painted red finish and battery power on an eighteen volt system.
The reason to buy is a large amount of torque from a battery tool for big fasteners. The limit is the unlisted battery and charger, and an item that is heavy to hold overhead.
Who it's for
Wheel nuts, suspension bolts and heavy machinery are the intended work. If you need to drive small screws, a compact hex driver is a better match, since this is a socket wrench.
Pros and cons
- High stated torque
- Socket end for sockets
- Battery powered, no hose
- Battery and charger not listed
- Heavy at the listed weight
- Inch sizes only
Performance notes
The impact mechanism builds and releases rotational energy in short hits, which breaks heavy fasteners loose. Battery condition affects how well it reaches full torque. A socket end attaches sockets directly, so socket quality matters.
