Overview
Milwaukee builds this angle grinder around a battery pack instead of a cord, so a worksite without power outlets can still run cutting and grinding wheels. The motor spins the spindle at a fixed top speed for fast stock removal.
Going cordless removes the extension lead and the trip hazard from metal prep, cutoff and cleanup jobs. The gaps are practical, because the listing does not name a wheel diameter, a battery in the box or any guard and switch details.
Who it's for
Fieldwork, scaffolds and remote sites where a cord is awkward make the most of a battery grinder. Shop users with a plug in nearby and no battery system gain little from paying for the cordless format.
Pros and cons
- Cordless freedom on site
- High wattage motor rating
- Fast spindle speed for stock removal
- Battery platform shared with other tools
- Wheel diameter not listed
- Battery and charger not confirmed
- Heavy for overhead work
- Guard and switch type not described
Performance notes
Wheel speed and motor power decide how fast the abrasive removes metal, and a battery-fed motor holds its speed as long as the pack has charge. Pushing hard slows the wheel and drains the pack faster, so letting the wheel do the work gives more cuts per charge.
