Makita GA012G 40V XGT Cordless Brushless Angle Grinder 115mm

The Makita GA012G (655369) is a 40V XGT cordless brushless angle grinder taking 115mm (4½") discs. It sits in Makita's XGT platform launched in 2020 as a heavy-duty cordless system built for serious work. This is a tool aimed squarely at trade users who need cordless power without compromise. The brushless motor delivers strong, consistent performance and runs cooler and longer than a brushed equivalent.

The motor features soft start to reduce initial torque spike. No-load speed hits 8,500 rpm. It runs on Makita 40V XGT lithium-ion batteries sold separately which can fully recharge in as little as 28 minutes. Two-way digital communication between tool and battery keeps performance optimised throughout the charge cycle.

Safety features are a real strength here. The rapid electric brake stops the disc fast when you release the paddle switch. AFT (Active Feedback-sensing Technology) shuts the tool down instantly if rotation speed suddenly drops protecting the user from kickback events. Anti-restart protection stops accidental start-up. Tool-free guard adjustment makes setup quick. Weight runs between 3.0 and 3.6 kg depending on battery fitted.

For cutting metal or grinding welds this grinder handles it well. The paddle switch cuts power the moment you let go a genuine safety advantage on site.

The GA012G uses a brushless motor, which means less friction, lower heat and a longer service life compared to brushed motors. Soft start reduces the torque spike when you pull the trigger. Running at 8,500 rpm on a 115mm disc it handles metal cutting and grinding well. The AFT system monitors disc rotation speed and shuts the tool down if it detects a sudden drop a real-world kickback guard. The rapid electric brake stops the disc fast on paddle release. Two-way digital communication between the 40V XGT battery and tool keeps output steady throughout the charge cycle.

Always fit the correct guard use a grinding guard for grinding discs and a cutting guard for cutting discs. Check every disc is rated to at least 8,500 rpm before fitting. Use the side handle at all times for two-handed control. Wear eye protection, gloves and hearing protection. The GA012G's AFT system and rapid electric brake add protection but are not a substitute for correct technique. Never reach near the disc until it has fully stopped.
