Greenworks has made a significant move in the budget-conscious power tool market by introducing a compact 3/8-inch impact wrench that delivers professional performance without the professional price tag. The IW5370 model is now available for under $70, positioning itself as a game-changer for homeowners and mechanics who need reliable fastening power without breaking the bank.
What Makes This Impact Wrench Stand Out
The Greenworks Pro IW5370 combines a brushless motor with practical features that appeal to both casual users and professionals. It delivers up to 2,500 RPM and generates 3,600 impacts per minute, producing 400 foot-pounds of breakaway torque. This spec places it squarely in the compact category, offering enough power for automotive work, general maintenance, and mechanical applications without the bulk of larger models.
What really sets this tool apart is its three adjustable power settings: 150, 400, and 300 foot-pounds of output. This graduated approach prevents users from accidentally stripping smaller fasteners by delivering excessive force. Most shoppers working on vehicles or equipment don’t need maximum power for every task, making these settings genuinely useful rather than gimmicky.
The automatic mode adds another layer of control. Once a bolt or nut breaks loose, the wrench automatically reduces spin-down to prevent the fastener from launching off at high speed. This feature proves invaluable when working around loaded fasteners on machinery or vehicles, where runaway motion can cause damage or injury.
Built-In Features That Save Money Down the Road
The integrated tri-LED work light addresses a common frustration: working in tight spaces or under-dashboard areas where natural light doesn’t reach. Users can activate the lights independently for ten minutes of illumination, or they engage automatically for ten seconds when the trigger is released. This single feature can eliminate the need to purchase a separate work light, offsetting part of the tool’s cost.
Additional conveniences include a tether-ready lanyard loop for safety when working at heights and a two-position belt hook for ergonomic carry. The IW5370 weighs just 2.6 pounds as a bare tool and 3.7 pounds with a 2.0Ah battery, making it lighter than comparable mid-torque models from competing brands.
How Greenworks Compares to Premium Brands
Price comparisons reveal why this announcement matters to budget-conscious buyers. The Greenworks IW5370 sells for $79.99 bare tool, or even less at select retailers like Walmart at $69.97. Compare that to Milwaukee’s M18 Fuel model at $249 or DeWalt’s Atomic DCF923 at $239, and the value becomes striking. The Greenworks delivers competitive breakaway torque and impact rates while costing roughly one-third as much.
Shoppers investing in the Greenworks 24V platform gain additional savings since over 200 tools and lawn care products use the same batteries. Those already holding batteries can justify purchasing this wrench for under $70 without battery costs, stretching their tool investment even further.
Understanding When You Actually Need This Model
The 3/8-inch format represents a deliberate design choice rather than a limitation. Professionals working on heavy equipment, commercial vehicles, or severely corroded fasteners may eventually outgrow the 400 foot-pound rating. For these applications, larger impact wrenches deliver the additional torque needed for stubborn jobs.
However, Greenworks offers four Pro-focused impact wrenches in its 24V lineup, including the IW5550 with 560 foot-pounds and larger models with 750 and 1,430 foot-pounds respectively. The key insight for shoppers is that purchasing the compact IW5370 alongside a mid-torque model still costs less than a single premium-brand wrench. This makes building a versatile tool collection financially feasible for budget-conscious buyers.
Long-Term Value
Greenworks backs the IW5370 with a five-year limited warranty, providing peace of mind beyond what many budget tools offer. The straightforward single-button interface for mode selection keeps operation simple without sacrificing control.
For automotive enthusiasts, DIY mechanics, and homeowners tackling maintenance projects, this compact wrench arrives at exactly the right price point and power level. It won’t replace purpose-built 1/2-inch impact wrenches for heavy-duty applications, but it eliminates the need to purchase expensive professional-grade tools for everyday work. The under-$70 price tag means more people can afford to own an impact wrench, shifting the tool from luxury to practical necessity in home garages and workshops across the country.
