Our take on the Milwaukee Electric Tools 2680-20 M18 CUT-OFF/ GRINDER

The Milwaukee 2680-20 is an 18V cordless 4.5-inch cut-off and grinding tool built on the M18 battery platform. It spins at up to 9,000 RPM and uses a tool-free guard and spindle lock, so wheel changes are quick. It suits metalworkers, welders and fabricators who want grinder power without a cord, and it shares batteries with the rest of the M18 lineup. Against corded 4.5-inch grinders it gives up some sustained power and runtime, and against brushless rivals it is heavier on battery draw, but owners value the convenience and the platform compatibility.

Pros
  • Runs on the widely shared M18 18V battery system
  • Up to 9,000 RPM for a cordless 4.5-inch tool
  • Tool-free guard and spindle lock speed up wheel changes
  • Compact body for a cordless grinder
  • Includes a wrench for wheel swaps
Cons
  • Battery capacity is modest, so runtime is short under heavy load
  • Corded grinders deliver more sustained power for long jobs
  • Heavier and bulkier than a corded equivalent with the battery fitted
  • Not brushless, so it drains batteries faster than newer M18 grinders

  • Battery platformPraisedBuyers like sharing M18 packs with their other Milwaukee tools.
  • Wheel changesPraisedThe tool-free guard and spindle lock make swapping wheels fast.
  • WeightMixedThe body is compact, but with a battery fitted it feels heavier than expected.

Questions and answers

Does the 2680-20 come with a battery and charger?
It ships with one battery and a wrench. A charger is not listed, so check the kit contents before buying if you need one.
What size wheels does it take?
It accepts wheels up to 4.5 inches in diameter with a 7/8-inch arbor, the common size for angle grinders.
Is it good for cutting metal?
Yes. At up to 9,000 RPM it handles cut-off work on steel, rebar and sheet metal well for short jobs.
How does it compare with a corded 4.5-inch grinder?
It is more portable but gives up sustained power and runtime. For long continuous grinding, a corded grinder is the better choice.
