Milwaukee M18 FUEL High Torque ½” Impact Wrench with Pin Detent Kit

When I first got my hands on the Milwaukee M18 FUEL High Torque ½” Impact Wrench with Pin Detent Kit (model 2766-22), I was curious to see if it lived up to the hype. This tool promises a lot—750 ft-lbs of fastening torque and a whopping 1100 ft-lbs of nut-busting torque—all wrapped up in a compact, portable package. After spending some time with it, I can confidently say that it delivers on its promises and then some.

Design and Build Quality

The first thing I noticed about this impact wrench is its robust build. At 8.1 inches in length, it’s surprisingly compact for the amount of power it packs. This makes it versatile for working in tight spaces, which is a significant advantage in automotive and construction applications. The rubber overmold grip adds a level of comfort that’s appreciated during extended use. While it does weigh in at 7.1 lbs, the balance and ergonomics make it manageable even for longer jobs.

Performance and Power

This tool is a powerhouse. The 750 ft-lbs of fastening torque and 1100 ft-lbs of nut-busting torque are more than ample for most heavy-duty tasks. I tested it on a variety of stubborn fasteners, including rusted bolts and lug nuts torqued to 450 ft-lbs, and it handled them with ease. The 4-Mode DRIVE CONTROL is a fantastic feature, allowing for precise torque adjustments. Mode 4, with its Bolt Removal mode, reduces RPM to 750 after the fastener breaks loose, which is useful for preventing runoffs. However, I found Mode 3 to be the most efficient for general use.

Usability and Features

One of the standout features is the ½” pin detent anvil, which ensures socket retention. While this means the sockets won’t fly off, it does require a bit more effort to remove them—usually involving a small screwdriver or nail to push in the retaining pin. This slight inconvenience is a trade-off for the added security, which I found worthwhile, especially in high-torque situations.

The LED light is another thoughtful addition. It illuminates the work area effectively, making it easier to see what you’re doing, particularly in dimly lit environments. The variable speed trigger offers excellent control, and the direction control switch, with its Forward, Lock, and Reverse positions, is intuitive and easy to use.

Battery Life and Charging

The kit comes with two RedLithium XC5.0 18-volt Resistant Battery Packs, each featuring a 4-level power indicator. These batteries are interchangeable with other Milwaukee M18 tools, adding to the convenience. During my tests, I found that one fully charged battery lasted through several hours of continuous use. When it did run down, the included dual charger, which supports both M12 and M18 batteries, made quick work of topping it off.

Portability and Versatility

One of the primary advantages of this impact wrench is its cordless design. Gone are the days of being tethered to an air compressor or electrical outlet. The rugged plastic carrying case that comes with the kit is another plus, providing a durable and convenient way to transport the tool, batteries, and charger. This makes it an excellent option for on-the-go mechanics or anyone who needs a powerful, portable solution.

Drawbacks

While there’s a lot to love about this tool, it’s not without its downsides. The weight, at 7.1 lbs, can become cumbersome during prolonged use, especially if you’re working in awkward positions. Additionally, the pin detent system, while secure, adds a step to the process of changing sockets, which can slow you down slightly.

There’s also the price to consider. This is not a budget tool, but given its performance and the inclusion of two batteries and a charger, I believe it offers good value for money.

Final Thoughts

The Milwaukee M18 FUEL High Torque ½” Impact Wrench with Pin Detent Kit is a formidable tool that delivers on its promises. Its compact design, coupled with immense power and versatile features, makes it a valuable addition to any professional’s toolkit. Whether you’re working in automotive repair, heavy machinery, or even DIY projects, this impact wrench has the muscle to handle the toughest jobs.

I would recommend this tool without hesitation. Its performance, build quality, and thoughtful features make it a standout in its category. While it does come with a heftier price tag, the investment is justified by the time and effort it saves, not to mention the convenience of a cordless design. If you’re in the market for a high-torque impact wrench that can go toe-to-toe with pneumatic tools, the Milwaukee M18 FUEL is an excellent choice.
