Overview
The Milwaukee 3450-20 is a 12V battery powered impact driver rated to 3000 RPM and weighing just 1.3 pounds. The -20 ending follows Milwaukee's usual pattern for a bare tool, sold without battery or charger.
At 1.3 pounds this is built for one-handed work overhead or in cramped spots, trading some top-end speed for lighter weight and Milwaukee's 12V system. The 2 by 6 by 6 inch dimensions describe a short, stubby driver rather than a long-reach tool. As with other bare-tool listings, it only pays off if you already own Milwaukee's M12 batteries.

- 3000 RPM, 2 amp rating
- 1.3 pounds
- Bare tool, model ends in -20
Who it's for
Milwaukee M12 owners who want a light second impact driver for overhead or tight-clearance work. Not the choice for buyers needing maximum driving speed or starting a battery platform from zero.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1.3 pounds, light for overhead work
- Compact 2 x 6 x 6 inch body
- Fits existing Milwaukee M12 batteries
- Sold as a bare tool, no battery or charger
- 3000 RPM is lower than some larger impact drivers
Performance notes
3000 RPM on the 12V platform trades some speed for a lighter, more compact tool at 1.3 pounds, which pays off in overhead work or tight clearances where a heavier driver tires the wrist. The 2 by 6 by 6 inch body keeps reach short, useful in cabinets and enclosed spaces.
