Overview
Milwaukee's M12 3/8 inch cordless ratchet, model 2457-20, sold as a bare tool without battery or charger. Runs on the 12 volt M12 battery platform and weighs 1.61 pounds.
The bare tool listing means it is meant for buyers who already own M12 batteries and a charger, typically because they have other Milwaukee M12 tools already. Its low weight and slim head are built for reaching fasteners in tight engine bays and under dash spaces where a full size ratchet will not fit.
- M12 12 volt 3/8 inch cordless ratchet
- Bare tool, battery sold separately
- 1.61 pound weight
- Compact head for tight spaces
Who it's for
Auto and maintenance technicians who already own M12 batteries and want a compact ratchet for tight spaces. Not a fit if you need a complete kit with battery and charger included.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact head suited to tight engine bay work
- Lightweight at 1.61 pounds for one handed use
- Runs on the widely used M12 battery platform
- Sold as a bare tool without battery
Performance notes
At 1.61 pounds, the low weight and slim head are meant for one handed use in cramped spaces such as engine bays, where a corded or larger cordless ratchet cannot reach. Being a bare tool, actual runtime depends entirely on whatever M12 battery you pair it with.
