Overview

The Makita XAG04Z is a cordless 4-1/2 inch to 5 inch angle grinder built around Makita's brushless motor and sold as a bare tool, with no battery or charger included. It suits owners of the Makita 18V LXT battery platform who need a cutting and grinding tool without a cord.

Automatic Speed Change lets the motor hold torque as the load changes, and Active Feedback sensing Technology cuts power if the wheel binds suddenly, which matters more on a tool this size than the spec sheet alone suggests. Reviewers who cross shopped it against a Milwaukee Fuel grinder called out the price gap in Makita's favor while still getting a brushless motor.

  • Brushless motor with Automatic Speed Change torque control
  • Active Feedback sensing shutoff on sudden wheel bind
  • Tool only, battery and charger sold separately
  • 4-1/2 inch to 5 inch wheel capacity

Who it's for

DIYers and tradespeople already carrying Makita 18V LXT batteries who cut or grind metal around the house or job site. Less suited to someone starting from zero on batteries, since this tool ships without one.

What buyers say

From Amazon customer reviews.

Buyers praised the cutting and grinding power and several called it a better value than the comparable Milwaukee Fuel grinder, with one owner switching brands over a 60 dollar price gap. The recurring complaints were the lack of a tool less disc change, a battery that drains faster on thicker metal, and a heavier feel typical of cordless grinders in this class.
