Cordless power tools are becoming increasingly popular for shop use, primarily due to the convenience offered (no air hoses or power cords to drag around). This offering from ACDelco is one beefy cordless workhorse. Like many techs, I’ve been through my fair share of cordless tools over the years, some good, some bad, some great and some a downright waste of money.

The new 90-degree angle 3/8-inch drive cordless impact wrench from ACDelco is definitely in the “wow” category. When you run across a tool that does what it’s supposed to do and you fall in love with it at the same time, it’s a pleasure to recommend it to others.

The ARI2044 is not a cheesy battery-powered toy designed for the occasional-use DIY market. This is professional grade.

The kit (housed in a heavy-duty plastic case) includes the wrench, two rechargeable lithium ion batteries and a battery charger.

The cool factors include an LED light that illuminates the socket area whenever the trigger is depressed, a very tactile and secure grip surface, a variable speed trigger that’s conveniently long for no-fumble access, a digital clutch system (with LCD screen display) that allows you to easily reduce or increase operating torque within six settings, a thoughtfully installed rubber bumper surround at the anvil head, and handy indicator lights that inform you of battery life and of achieved torque.

The 18V impact wrench features a 90-degree angle head and measures 14.25 inches in overall length. Weight is a mere 3.92 pounds, and it’s designed with excellent handling balance.

Torque value stages

A torque control adjustment is featured at the left of the LCD screen, featuring a + and a – button that allow you to scroll to the desired clutch stage. The lab-tested values are as follows:

Stage 1: Average 14.8 ft.-lbs.

Stage 2: Average 22.1 ft.-lbs.

Stage 3: Average 33.2 ft.-lbs.

Stage 4: Average 40.6 ft.-lbs.

Stage 5: Average 51.7 ft.-lbs.

Max: 60 ft.-lbs.

When the selected torque is reached, the tool de-clutches and a green indicator light illuminates. When battery charge drops below 14.4V, power cuts off and a red indicator light illuminates, while the screen displays “LV” (low voltage). In addition to the low-power cut-off and warning, if tool operating temperature reaches over 140 degrees Fahrenheit, power shuts down, the red light illuminates and a screen message “OT” (over temperature) is displayed. In other words, this is an “intelligent” cordless wrench.
