Our take on the Milwaukee 6143-31 11 Amp 4-1/2 / 5 Braking Small Angle Grinder Paddle No-Lock

The Milwaukee 6143-31 is a corded 4-1/2 to 5 inch angle grinder built around an 11 amp, 1,400 MWO motor that spins at 11,000 RPM. Its standout feature is the Rapid Stop brake, which halts the wheel in a fraction of the time a standard grinder takes, plus an electronic clutch that cuts power on bind-up. The paddle no-lock switch means the tool only runs while the paddle is held, which suits welders, fabricators and metalworkers who want a fast, controlled grinder for cutting and grinding. Against rivals like the DeWalt DWE402 and Makita 9565CV, it trades variable speed for the brake and anti-kickback electronics, and it is heavier and pricier than basic grinders.

What reviewers say

  • 4.3 / 531 ratings

Owners rate it highly for the brake and the smooth, powerful motor, and many say the anti-kickback clutch has saved them from a snag. Complaints center on weight and the no-lock paddle during long grinding jobs.

What people mention
  • BrakePraisedOwners say the Rapid Stop brake brings the wheel down quickly, which speeds up wheel changes and adds safety.
  • KickbackPraisedReviewers report the electronic clutch shuts the tool down on bind-up instead of twisting in the hand.
  • WeightCriticisedSeveral owners find it heavy and long compared with basic grinders, especially for overhead work.
  • SwitchMixedThe paddle no-lock switch is seen as safer, but holding it for long grinding passes tires the hand.
  • PowerPraisedThe 11 amp motor is described as holding speed well under load on steel.

Questions and answers

Does the brake really stop the wheel faster?
Yes. The Rapid Stop brake slows the wheel in a fraction of the time a standard grinder takes, which matters when you set the tool down or change wheels.
Can I use 4-1/2 inch wheels as well as 5 inch?
Yes. It accepts both 4-1/2 and 5 inch Type 27 wheels on the 5/8"-11 spindle, so you can use either size.
Is it variable speed?
No. It runs at a fixed 11,000 RPM, so for polishing or delicate work a variable-speed model is a better fit.
What does the paddle no-lock switch mean?
The grinder runs only while you hold the paddle and stops when you release it. There is no lock-on button, so it cannot be left running unattended.
What comes in the box?
The grinder and an anti-vibration side handle. Wheels and a wrench are not included, so plan on buying those separately.
How does it compare with the DeWalt DWE402?
The Milwaukee adds a brake and an electronic kickback clutch, which the DWE402 lacks. The DeWalt is lighter and simpler, so the choice comes down to whether you want the safety electronics.
