Overview
Part of Milwaukee's M18 platform, the 2658-20 is an 18-volt cordless impact driver weighing 2.9 pounds; the -20 suffix marks it as a bare tool sold without a battery.
As a bare tool, the 2658-20 is meant for buyers who already own M18 batteries and chargers, which keeps the price down compared with a full kit. This model has been part of Milwaukee's impact driver line for several years, so compatible batteries and accessories are widely available.

Performance notes
Milwaukee rates the M18 platform's output by battery choice, so the 2658-20's actual torque and speed vary with which battery is paired with it. Its 2.9 pound body sits in a fairly light class for a cordless impact driver, helping with one-handed control on repetitive fastening tasks.
