Cordless convenience comes with extra weight here; a solid pick if working without an outlet matters more than shaving pounds off the tool.

Overview
Metabo's G18ST angle grinder runs on battery power and spins its disc at 6,000 RPM, weighing 10.8 pounds as part of the brand's cordless grinder lineup.
Cordless angle grinders trade outlet dependence for battery runtime, which matters most on jobsites without easy power access. At 10.8 pounds this is on the heavier side for a handheld grinder, so expect more fatigue on overhead or extended work than with a lighter corded model. Voltage and motor wattage figures in the source data conflict with a cordless power source, so those numbers are left out here rather than reported as fact.
- Battery-powered angle grinder
- 6,000 RPM rated speed
- 10.8 pound tool weight
- Metabo cordless grinder line
Who it's for
Tradespeople and serious DIYers doing metal fabrication, weld cleanup, or masonry cutting away from an outlet get the most from this grinder. Occasional users who only need a grinder a few times a year may find the weight and cordless-tool investment hard to justify.
Pros and cons
- Cordless, no outlet needed on site
- 6,000 RPM disc speed suits metal cutting and grinding
- 10.8 pounds is heavy for extended handheld use
- Battery and charger inclusion is not confirmed in the listing data
Performance notes
The 6,000 RPM disc speed here lands in a typical range for cutting and grinding wheels rated for angle grinders, though actual cutting speed also depends on disc diameter and material, neither of which is listed. Tool weight of 10.8 pounds does not include the battery, which adds further heft in use.
