Milwaukee M12 Soldering Iron (Bare Tool) Review

By Milwaukee · Updated 2026-09-15

8.6 / 10 · our score

A rugged cordless soldering iron built on Milwaukee's M12 battery platform. It is sold as a bare tool, so it makes most sense if you already own M12 batteries — then it is a tough, truly cordless iron for automotive, electrical and field work.

Our verdict

If you already have M12 batteries in the van or garage, this is the easiest cordless iron to justify: it slots into a system you own and handles wiring, connectors and field repairs with no cable. For delicate PCB work a slim pen iron is nicer to hold, and if you do not own M12 batteries the total cost climbs quickly — so this is a pick for existing Milwaukee users first.
