The Milwaukee 2657-20 is an older M18 2-speed 1/4 in. hex impact driver built for users who want more control than a single-speed brushed driver. The supplied scrape did not separate a full dedicated spec set, but Milwaukee positions it as a cordless tool-only impact driver for standard fastening work on the M18 platform. It suits buyers prioritizing low-speed control for smaller hardware and general installation tasks.
Is the 2657-20 a tool-only package?
Yes. Batteries and charger are sold separately.
What collet size does the 2657-20 use?
It uses a standard 1/4 in. hex quick-change collet.
Why would someone choose the 2-speed version?
The added speed range can make it easier to manage smaller fasteners and reduce overdriving compared with a single high-speed setting.
