Milwaukee vs. HILTI Impact Wrench Review

1. Milwaukee 2767-20 M18 Fuel High Torque 1/2-Inch Impact Wrench with Friction Ring

The Milwaukee brand has a vast variety of various impact wrenches on the market at the moment. You’ll most likely love the variety because if you need a different wrench for some reason like a pin detent, then Milwaukee has it and you don’t need to change battery platforms.

While the head of this tool is quite big, it is still the most compact head in its class and price range. In fact, this power tool only weighs 7.5 pounds and that is with a battery.

Furthermore, the brand designed this with a brushless motor. The brushless motor provides more efficiency than its counterpart – the brushed motor doesn’t. Its motor gives 1,000 feet per pound of fastening torque and 1400 feet per pound of nut-busting torque.

In terms of grip, it is your typical Milwaukee grip with the rubber over-mold and textured for extra grip. Aside from that, this tool utilizes a variable speed trigger in order to control the speed of the wrench. As with the other Milwaukee equipment, their trigger is quite easy to control and maintain at a consistent speed.

On the base of this impact wrench, you can find 3-speed selectors along with a bolt removal setting. The bolt removal setting provides the consumer more control when removing fasteners by slowing to 750 RPM once the fastener has been busted loose.

The HILTI three-speed 18 volts impact wrench does not appear to be a brushless model with only 743 inches per pound of torque. It rates as the lowest torque output of any of the high-performance impact wrench out there.

Out of the box, this power tool provides its compact designation at 5.8 inches long, 3.7 inches wide, and 8.8 inches high with the battery. It is not the most compact you’ll see, but it is in the ballpark. Its 3-speeds, toggled with a button on the tool base can deliver 531, 973, and 1,550 inches per pound of torque on paper.

This bare tool is quite light and using its 2.6 Ah battery can keep it pretty nimble, but there is no getting around the fact that its 5.2 battery is quite heavy. Most likely, its slickest feature is its four LEDs, boldly surrounding the chuck on its head.

They are bright and they illuminate your working station like few others. They also make what’s essentially a spotlight on your work and it is quite beneficial.

On the other hand, its grip is comfortable in the hand and its over-mold extends up around the back of the tool body for extra protection. Talk about protection, HILTI backs its products with a warranty that you can’t find elsewhere.

Most of them come with twenty years of limited warranty, 2 years wear and tear, and a 1-day turnaround on repairs. These all imply that the company believes in the durability of its products.

Where Does This Impact Wrench Fits?

By comparison, this impact wrench from HILTI claims 400 IPM – which is actually the fastest you’ll see thanks to the triple hammer mechanism. However, it is also a hundred bucks pricier more than the certain models in the same brand and specs.

HILTI usually beats other equipment out in both price and specs; this just happens to be one time that it sits in the center of both. Still, HILTI will surely deliver sufficient for the vast majority of your work.

Now, for a little room for an upgrade, you might want to purchase a kitted package if you want a belt hook as the bare tool doesn’t come with one. You’ll probably love to see a magnet or a bit holder somewhere on this power tool.

It is a little feature that comes in very conveniently. All things considered though, it is hard to go wrong with this tool since it is hard to find anything in medium and light-duty fastening that it doesn’t perform well.

Furthermore, the HILTI Company recently announced that they will be transitioning to a 22volts battery. The new 22 volts battery will work with all new as well as previous models of HILTI 18volts lithium-ion cordless tools, providing for a seamless transition for existing HILTI cordless tool consumers.

What More It Offers?

Not only do the new 22 volts battery packs work with HILTI’s 18 volts power tools, but the battery packs are also the cost, weight, and size as the 18 volts lithium-ion battery packs. In fact, the new battery packs are said to provide an increase of 15%-30% in work per charge.

Moreover, the brand adds that the batteries perform up to 20% more work per charge, depending on temperature, user, insert, and application, compared to the HILTI 18 volts batteries and up to 50% more work per charge compared to competitive 18 volts per 5 amps hour solutions.

There are upgraded electronics and an updated CMS or Cell Management System which allows for deeper discharging of the battery, in short, prospective consumers can squeeze even more energy out of the new battery packs.

In addition to the new 22 volts battery packs, there will also be new 22 volts cordless power tools. And yes, the HILTI’s 18 volts battery packs will work with the new tools as well.

Overall, 18 volts tools powered by 22 volts batteries will benefit from more work per charge, in short at least longer operation.
