Our verdict

A known-name air impact wrench built for shops already running pneumatic tools; without a compressor on hand, this one will not work for you.

Overview

The Ingersoll 231C is an air-powered impact wrench, one of the model numbers longtime mechanics reach for by name rather than description. Weighing 5.8 pounds, it sits at the heavier end for a hand tool, typical for pneumatic impacts built around durability rather than portability.

There is no cordless battery pack here, no voltage rating, no charge time; this runs off shop air, which is why garages that already own a compressor keep coming back to this model line. The listing itself is thin on spec detail beyond weight, so buyers used to seeing torque figures up front should check Ingersoll's documentation before ordering.

  • 5.8 lbs item weight

  • Category: Tools, Impacts

Who it's for

Suits a home garage or small shop that already runs an air compressor and wants a dedicated impact wrench for lug nuts and stuck fasteners. Less suited to anyone without a compressor, since this tool has no cordless mode.

Pros and cons

Pros
  • No battery to charge or replace
  • Traditional air-tool durability
  • Familiar model in mechanic shops
Cons
  • Requires a compressor, not standalone
  • Listing lacks torque and drive-size specs
  • At 5.8 lbs, heavier than compact cordless options

Performance notes

As a pneumatic impact, output depends on the compressor feeding it, specifically CFM and PSI at the tool, more than on the wrench itself. That is standard for air tools generally, but it does mean two shops running the same 231C can get different results depending on their compressor setup.
