Overview

The ARW1209-P2 from ACDelco is a 12 volt cordless impact weighing 2.7 pounds, sized for compact, one-handed use rather than heavy structural work. That combination of low voltage and light weight fits the sub-compact class of impact tools.

At 12 volts and under 3 pounds, this reads as a compact impact meant for lug nuts, small fasteners, and reach-in jobs rather than high-torque structural work. ACDelco's automotive lineage lines up with that kind of use, though torque figures are not part of the listed data.

Who it's for

A fit for anyone who wants a light, compact cordless impact for automotive or general fastening work over a full-size, high-torque unit. Not the choice for jobs that call for maximum torque, since output figures are not confirmed here.

Performance notes

Voltage and weight are the two hard numbers here: 12 volts and 2.7 pounds together point to a compact tool built for control and reach rather than raw torque. Actual torque output is not listed, so buyers with a specific fastener spec should check ACDelco's page directly.
