- Already own Milwaukee M18 batteries? The 2720-20 uses them; the 2520-20 needs Milwaukee M12 batteries and a charger.
- Already own Milwaukee M12 batteries? The 2520-20 is the one that fits what you have.
- Starting from nothing: this is a battery-system choice more than a tool choice; compare the kit versions (2720-21, 2720-22), which add batteries and a charger.
- Evidence boundary: 7 spec rows are published by only one maker in the table below; unstated figures are treated as unknown rather than assumed.
From the published figures only; no testing. Rated figures from different makers are not measured the same way.
