About Makita GA004G 40V XGT Cordless Brushless Angle Grinder 115mm

The Makita GA004G (538303) is a 40V XGT cordless brushless angle grinder taking 115mm (4½") discs. Built for heavy-duty cutting and grinding without a power cable, it sits at the top of Makita's cordless range. This is a professional-grade tool aimed squarely at tradespeople who need serious cordless power on site.

The brushless motor with soft start reduces wear and extends tool life compared to brushed alternatives. It runs at 8,500 rpm no load speed. This is a body-only tool no batteries or charger are included. It uses the Makita 40V XGT lithium-ion battery platform, introduced in 2020. XGT batteries charge in as little as 28 minutes using a compatible rapid charger.

Safety is well covered. The GA004G has a rapid electric brake that stops the disc fast after release. Active Feedback Sensing Technology (AFT) shuts the tool down instantly if rotation speed drops suddenly. Anti-restart protection stops accidental start-up. The tool-free guard adjustment and top-mounted slide switch make it practical to use. Weight runs from 2.9 to 3.6kg depending on battery fitted.

Two-way digital communication between tool and battery optimises performance and reliability. The ADP10 adaptor lets you charge LXT and XGT batteries from one charger less clutter on site. A solid choice for demanding grinding and cutting work.

The Technology Explained

The GA004G uses a brushless motor which has no carbon brushes to wear out meaning longer service life and less maintenance. It runs at a fixed 8,500 rpm on Makita's 40V XGT platform a high-voltage system designed for demanding trade applications. Two-way digital communication between tool and battery monitors performance in real time. The rapid electric brake stops the disc fast after release. AFT technology detects a sudden drop in rotation speed and cuts power immediately. Soft start ramps up speed gradually reducing start-up torque and disc stress.

Using It Safely

Always fit the correct guard a grinding guard for disc grinding and a cutting guard for cut-off work. Check every disc is rated for at least 8,500 rpm before fitting. Use the side handle at all times for proper control. Wear eye protection, gloves and hearing protection this tool produces 81 dB(A) at the operator. The GA004G's rapid electric brake and AFT system add protection but do not replace safe working practice. Never remove the guard. Wait for the disc to stop fully before setting the tool down.
