Our take on the Corded Angle Grinder: 4-1/2 to 5″ Wheel Dia, 8,500 RPM, 5/8-11 Spindle 40V, Paddle Switch

The Makita GAG03Z is a cordless 40V angle grinder that takes 4-1/2 to 5 inch wheels and spins them at 8,500 RPM through a 5/8-11 spindle. It stands out for an electric brake, bind-up control and a paddle switch with lock-on, features that stop the wheel fast and cut kickback risk. It suits welders, metalworkers and fabricators who want corded-class grinding without a cord, and it is longer and heavier than a compact 18V grinder. It ships as a bare tool with a side handle, tool-less guard, wrench and a 5 inch INOX grinding wheel, so batteries and charger are separate.

Pros
  • Electric brake stops the wheel quickly after the switch is released
  • Bind-up control cuts power if the wheel jams, reducing kickback
  • Paddle switch with lock-on for long grinding sessions
  • Tool-less wheel guard for quick guard adjustments
  • Accepts both 4-1/2 and 5 inch wheels on a standard 5/8-11 spindle
  • Runs on Makita 40V batteries, no cord to manage
Cons
  • Bare tool: battery and charger sold separately
  • 16-1/8 inch body is long for tight spaces
  • No variable speed dial, so it is single-speed only
  • 40V batteries and chargers add cost if you are not already on the platform
  • Heavier than compact 18V grinders

Questions and answers

Does the GAG03Z come with a battery and charger?
No. It is a bare tool. The box has the grinder, side handle, tool-less 5 inch guard, lock nut wrench and a 5 inch INOX grinding wheel. You need a Makita 40V battery and charger.
What size wheels does it take?
It accepts 4-1/2 inch and 5 inch wheels with a 7/8 inch arbor on its 5/8-11 spindle. The included guard and wheel are 5 inch.
Does it have a brake?
Yes. It has an electric brake that slows the wheel quickly when you release the paddle, plus bind-up control that cuts power if the wheel jams.
Is it variable speed?
No. It runs at a fixed 8,500 RPM with no speed dial, so control comes from the paddle and your technique rather than from dialing down RPM.
Can I use it for cutting and grinding?
Yes, with the right wheel. It ships with a 5 inch 1/4 inch thick INOX grinding wheel for stainless; for cutting, fit a compatible cut-off wheel and the guard.
How does it compare with a corded 4-1/2 inch grinder?
It matches the 8,500 RPM and 5/8-11 spindle of many corded grinders and adds a brake and bind-up control, but it is longer and depends on 40V batteries rather than mains power.
