Our take on the Milwaukee 2880-20 M18 FUEL 4-1/2" / 5" Grinder Paddle Switch, No-Lock

The Milwaukee 2880-20 is an 18V cordless angle grinder on the M18 FUEL platform, accepting 4-1/2" and 5" wheels. Its POWERSTATE brushless motor spins at 8,500 RPM and Milwaukee rates the output as equal to an 11-amp corded grinder. The RAPIDSTOP brake halts the wheel in two seconds or less, and it adds a paddle switch, tool-free guard adjustment, kickback protection and an anti-vibration side handle. It suits metalworkers, welders and contractors who want corded-class cutting and grinding without an outlet; the trade-off against corded grinders is that runtime depends on the battery you fit, and batteries and charger are not included.

Pros

  • RAPIDSTOP brake stops the wheel in 2 seconds or less
  • Paddle switch with no lock-on, plus kickback protection
  • Tool-free guard adjustment
  • Anti-vibration side handle for long grinding sessions
  • Runs on the M18 battery platform
Cons

  • Runtime and power depend on which M18 pack you use
  • Heavier than a small corded grinder once a battery is fitted

About the Milwaukee 2880-20 M18 FUEL 4-1/2" / 5" Grinder Paddle Switch, No-Lock

The Milwaukee 2880-20 is a cordless M18 FUEL angle grinder for grinding and cutting metal. It takes 4-1/2 inch and 5 inch accessories and uses a 5/8"-11 spindle. It is a bare tool, so the battery and charger are not included.

A POWERSTATE brushless motor runs the grinder at 8,500 RPM and delivers output rated at 11A corded power. REDLINK PLUS intelligence handles communication between tool and battery, overload protection and performance management under load. With a HIGH OUTPUT battery, it is rated for up to 135 cuts per charge in 1/2 inch rebar.

The RAPIDSTOP brake stops accessories in 2 seconds or less. Published stop times are as low as 0.82 seconds for a cutting wheel and 1.67 seconds for an abrasive disc. An electronic clutch provides kickback protection.
