Overview
The Milwaukee 3485-20 is a 12 volt lithium-ion cordless grinder weighing 1.65 pounds, built for one-handed use on cutting, grinding or surface prep jobs where a full-size angle grinder is too bulky.
At 1.65 pounds this sits in Milwaukee's compact 12 volt line rather than its full-size grinder range, trading raw power for reach into tight spaces and reduced arm fatigue on overhead or awkward cuts.

Who it's for
Suits tradespeople and serious DIYers who already own Milwaukee's 12 volt battery platform and need a light, maneuverable grinder for metal work, deburring or tight-space cutting. Less suited to heavy material removal that calls for a full-size corded or high-voltage grinder.
Pros and cons
- 1.65 pounds for one-handed control
- Runs on Milwaukee's 12 volt lithium-ion platform
- 12 volts limits it against full-size corded grinders on heavy jobs
- Battery and charger availability depends on owning Milwaukee's 12 volt system
Performance notes
Being lithium-ion and 12 volt, output is scaled for control and portability rather than sustained heavy grinding, and the 1.65 pound weight keeps it maneuverable in one hand for longer stretches. That combination explains the steady demand among buyers doing precision or overhead work rather than bulk material removal.
