Milwaukee Tool just released the first cordless M18 FUEL Grinder 2783-22 with a rapid stop braking feature and kickback-reducing clutch solution, increasing job-site safety for grinder uses. The M18 FUEL 4-1/2” / 5” Braking Grinder has a built in brake that stops the grinder wheel in under 2 seconds. This safety technology coupled with an innovator accessory removal, FIXTEC nut, got our attention.

Using a Grinder

Building contractors do not use grinders every day, but when they do need them they are an invaluable tool. Grinders are designed for metal cutting, surface preparation, and concrete preparation.


Grinder Use

There are many uses were a grinder is the go to tool, such as:

  • Cutting or smooth metal against concrete or masonry
  • Cutting off misplaced rebar or anchor bolts flush to a foundation wall
  • Grinding concrete-form ties
  • Smoothing ridges left on concrete walls from form seams
  • Cutting tile backer board, plaster, or stucco
  • Cutting corner bead in place
  • Grind, cut, or surface prep meta

M18 FUEL Grinder 2783-22 Review

This new grinder measures 15 1/4 inches long and weighs only 6.1 pounds. It uses a paddle switch and the motor spin the 5/8″ arbor wheel at 8500 RPMs.

Many existing cordless braking grinders on the market are effective as cut-off tools, the M18 FUEL grinder in also powerful enough to grind, cut and surface prep.

The tools metal housing and gearing system is heavy duty and durable. Milwaukee used the same housing that they use in their high performance corded grinders. A protective screen called Job Site Armor™ protects the grinders motor and prevents debris contamination during grinding in cutting operations.

Rapid Stop Braking, Kickback-Reducing Clutch and Anti Vibration

Safety has become a major focus with tool manufacturers, and Milwaukee is paying attention. Tool buyers and users, today not only buying tools to get the job done, efficiently, but also safely.

This new rapid stop breaking feature stops the grinding wheel in under 2 seconds, I was impressed. A built in kickback-reducing clutch helps eliminate the tool from spinning out of the operators hands causing injury.

An anti-vibration handle reduces vibration, and increases user control and comfort. The grinders durable housing has a thin body design, which works well with balance and handling ergonomics.

For safety, there is no lock on for this tools paddle switch.
