Overview

The Milwaukee 2566-20 is a compact impact tool from Milwaukee's M12 line, weighing 1.6 pounds. The -20 in Milwaukee's model numbers typically marks a bare tool sold without a battery or charger.

At 1.6 pounds this sits in Milwaukee's stubby or compact impact class rather than a full-size unit, and the light weight is the point for one-handed work in tight engine bays or cabinets. Since the listing is a bare tool by Milwaukee's usual naming convention, buyers already on the M12 platform get the most value, while anyone starting from scratch will need to add a battery and charger separately.

Who it's for

Fits Milwaukee M12 owners who need a compact impact tool and already have compatible batteries. Less suited to a first-time buyer who wants a complete kit out of the box.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

  • Fits Milwaukee's M12 battery platform
  • Strong recent purchase volume
What to check first
  • Bare tool, battery and charger likely not included
  • No torque spec given in this listing

Performance notes

Compact impact tools in this weight class trade some torque ceiling for maneuverability, making them suited to fastener work in confined spaces rather than heavy lug nut removal. Being part of the M12 line, output is set by the battery pairing rather than the tool alone.
