Greenworks has just released a compact 3/8-inch impact wrench that challenges the conventional wisdom about power tool pricing. The new model delivers professional-grade features at a fraction of what Milwaukee and DeWalt charge for comparable compact tools, marking a significant shift in how budget-conscious buyers can access quality impact wrenches without spending premium prices.

What Makes This Wrench Stand Out for Buyers

The Greenworks Pro IW5370 sits in a sweet spot for everyday automotive and mechanical work. It generates up to 2,500 RPM with 3,600 impacts per minute and delivers 400 foot-pounds of breakaway torque paired with 270 foot-pounds of fastening torque. Those numbers mean the tool can handle removing stubborn bolts and driving fasteners on vehicles, equipment maintenance, and general repair tasks without the bulk and weight of heavier models.

The real advantage becomes clear when you look at what you get for the money. A Milwaukee M18 Fuel compact impact wrench runs around 249 dollars, while a DeWalt 20V Atomic model costs approximately 239 dollars. The Greenworks bare tool starts at 79.99 dollars, with Walmart currently offering it for 69.97 dollars. You’re getting legitimately competitive specifications at roughly one-third the price of established brands.

Smart Power Control Features

Rather than offering a single maximum-power setting, this wrench includes three distinct power levels at 150, 400, and 300 foot-pounds. This matters because smaller fasteners can easily strip when hit with full force. Having adjustable settings lets you match the tool’s output to your specific task, preventing damage to delicate bolts and nuts.

The automatic mode represents another thoughtful addition. Once a fastener breaks loose, this feature prevents the wrench from continuing to spin at high speed. When you’re removing nuts and bolts under heavy load, Auto Mode stops the runaway spinning that typically occurs, giving you better control and reducing the risk of dropping components or losing your grip.

The integrated LED work light deserves mention as a practical feature often overlooked in tool reviews. Three LEDs surround the anvil and activate with a button press, staying illuminated for ten minutes. They also turn on when you pull the trigger and remain lit for ten seconds after release. This built-in light eliminates the need to carry a separate flashlight for tight spaces or low-light automotive work, similar to designs professionals have praised on premium competitors.

Size and Weight Advantage

At 2.6 pounds as a bare tool and 3.7 pounds with a 2.0-amp-hour battery, the IW5370 weighs significantly less than larger impact wrenches. The 5-inch head length makes it much easier to work in confined spaces where full-size tools simply won’t fit. Compared to Milwaukee and DeWalt compact models, it matches or beats them in weight and dimensions while maintaining competitive power specifications.

This balance between size and output is exactly why compact impact wrenches have become increasingly valuable. You get enough muscle to make jobs faster than hand tools allow, without the bulk that accompanies high-torque models. When you’re working on automobiles or general maintenance equipment, you rarely need the extreme torque reserved for heavy-duty industrial applications.

Compatibility and Warranty

Greenworks backs the tool with a 5-year limited warranty, a reassuring commitment to durability. More importantly, the 24V battery platform works with over 200 Greenworks tools, lawn care equipment, and lifestyle products. If you already own a Greenworks battery-powered drill, saw, or leaf blower, you can swap batteries with this wrench, dramatically improving the value proposition.

The two-position belt hook lets you secure the tool to your work belt, while the tether loop at the base allows you to leash the wrench when working at height. These are practical features that show engineers understood how professionals actually use these tools on the job.

Limitations Buyers Should Consider

This tool isn’t designed for every impact wrench job. If you regularly work on heavy equipment, large trucks, or encounter severely corroded fasteners, 400 foot-pounds may fall short. In those situations, stepping up to a 1/2-inch impact wrench makes sense. However, Greenworks offers larger models in their Pro line for buyers who occasionally need more power without wanting a single high-torque wrench as their only option.

The practical approach is treating the IW5370 as your primary compact tool for automotive and general maintenance work. High-quality wrench sets complement this impact wrench for precision work and smaller fasteners, creating a well-rounded toolkit without excessive redundancy.

The Verdict for Budget-Conscious Shoppers

The standout feature remains the pricing. Greenworks is delivering professional features at an entry-level investment. For those expanding their tool collection, pairing a compact impact wrench with multi-purpose hand tools provides flexibility for almost any fastening scenario. The multiple power settings, automatic mode, and integrated light transform what could have been a basic budget tool into something genuinely useful for serious work.

Given the aggressive pricing and solid specifications, this tool represents exceptional value for mechanics, DIY enthusiasts, and homeowners who want professional capabilities without premium price tags. Buyers assembling complete tool kits benefit from mixing impact tools with specialty wrenches designed for specific plumbing and mechanical applications. The Greenworks compact impact wrench fills a genuine need in today’s tool market.
