The Makita GA004G (655367) is a 40V Max XGT cordless brushless angle grinder taking 115mm (4½") discs. Built for heavy-duty cutting and grinding without a power cable it suits trade users who need serious cordless performance on site. The XGT platform launched in 2020 and uses an all-new battery system separate from the 18V LXT range.

The soft start brushless motor runs at 8,500 rpm no load. Brushless motors run cooler and last longer than brushed equivalents. This is body only no battery or charger included. It takes Makita 40V XGT lithium-ion batteries which recharge in as little as 28 minutes. No variable speed is listed.

Safety features are strong there's a rapid electric brake, anti-restart protection and Active Feedback Sensing Technology (AFT) which cuts the tool instantly if rotation speed drops suddenly. The top-mounted slide switch keeps control natural. Tool-free guard adjustment saves time on site. At 2.9 - 3.6 kg it's a solid tool. Good for cutting metal grinding welds and surface preparation.

Two-way digital communication between tool and battery maintains performance and allows future firmware updates. XGT batteries use impact-absorbing housings and the ADP10 adaptor lets you charge LXT and XGT batteries from one charger. Backed by Makita's manufacturer warranty.

The Technology Explained

The GA004G uses a brushless motor which means less friction, longer motor life and better efficiency compared to brushed designs. It runs at 8,500 rpm no load on Makita's 40V XGT platform a heavy-duty system with two-way digital communication between tool and battery for consistent performance. The 115mm disc size suits detailed and confined work. AFT monitors rotation speed and cuts power on sudden drops. The electric brake stops the disc fast. Soft start reduces jerk on trigger pull. All of this adds up to a safer, more controlled grinder for demanding site work.

Using It Safely

Always fit the correct guard use a grinding guard for grinding and a cutting guard for cutting discs. Check every disc is rated for at least 8,500 rpm before fitting. Use the side handle for two-handed control at all times. Wear eye protection, gloves and hearing protection. The GA004G's electric brake and AFT system add real protection but always wait for the disc to stop fully before setting the tool down.

Frequently Asked Questions

Does this angle grinder come with a battery and charger?

No, the Makita GA004G is sold as body only with no battery or charger included. You will need a compatible Makita 40V XGT battery and charger purchased separately.

Which battery platform does the GA004G use?

It uses the Makita 40V Max XGT lithium-ion battery platform launched in 2020. XGT batteries are not directly interchangeable with Makita's 18V LXT batteries but the ADP10 adaptor lets you charge both from the same charger.

What disc size does this grinder take?

The GA004G takes 115mm (4½") discs with a 22.23mm bore diameter and a maximum wheel thickness of 7.2mm. Always check that any disc you fit is rated for at least 8,500 rpm to match the tool's no load speed.

What safety features does the GA004G have?

It has three key safety systems: a rapid electric brake that stops the disc quickly after release, anti-restart protection that prevents accidental start-up and Active Feedback Sensing Technology (AFT) that shuts the tool down if rotation speed suddenly drops. These features make it significantly safer than a basic grinder.

What is Active Feedback Sensing Technology (AFT)?

AFT monitors the disc's rotation speed continuously and immediately cuts power if it detects a sudden drop, which typically indicates a snag or kickback situation. This is a genuine safety benefit for anyone cutting or grinding in tight or awkward positions.

What jobs is the Makita GA004G suited to?

It is designed for heavy-duty cutting and grinding applications including cutting metal, grinding welds and surface preparation. The 115mm disc size makes it well suited to detailed work and confined spaces compared to larger 125mm or 230mm grinders.

What guard and accessories are supplied with the GA004G?

The grinder features tool-free guard adjustment so you can reposition the guard without a spanner. Check the full listing for confirmation of exactly which accessories are included in the box as this can vary by retailer.

What warranty does the Makita GA004G carry?

It is covered by Makita's manufacturer warranty which covers all manufacturing defects for the normal lifetime of the tool. The warranty does not cover wear and tear or damage caused by misuse and does not affect your statutory rights.
