Overview
MILWAUKEE 2663-20 - a red impact drivers & wrench.
M18 is Milwaukee's core cordless battery platform, and the 2663-20 draws its 18 volt rating from that system. The -20 suffix commonly marks a bare tool in Milwaukee's naming, meaning battery and charger are typically sold separately from a listing like this one.
- Milwaukee impact tool, model 2663-20
- 18 volt M18 platform
- 4.7 average rating
Who it's for
Buyers who already own M18 batteries and a charger are the right fit, since the -20 suffix points to a bare tool rather than a kit.
Pros and cons
- 18 volt platform compatible with M18 batteries
- Sold as a bare tool without battery or charger
- No purchases recorded in the most recent tracking window
Performance notes
An impact tool works by delivering rotational force in rapid bursts rather than steady torque, which is what lets it drive fasteners without the operator absorbing kickback. Because this is a bare tool, actual runtime and torque output will depend on the battery pack it is paired with, not anything included in the box.
