About Makita GA055G 40V Max XGT Cordless Brushless Flat Head Angle Grinder 125mm

The Makita GA055G (839934) is a 40V Max XGT cordless brushless angle grinder with a 125mm disc. It's a flat head design built specifically for professional tradespeople who need to work in tight spots where a standard gear head grinder simply won't fit. Think metal fabrication near walls, cutting in corners or grinding in confined spaces.

The brushless motor delivers longer runtime and extended tool life compared to brushed alternatives. It runs on any Makita 40V XGT lithium-ion battery sold separately, body only. No load speed ranges from 3,000 to 9,000 RPM. There's no variable speed dial but the wide RPM range suits both cutting and grinding work.

The electric brake stops the disc fast after you release the switch. Active Feedback sensing Technology (AFT) cuts motor power if rotation suddenly drops protecting against kickback. Anti-restart protection stops the grinder firing up unexpectedly if the switch is left on when a battery is reconnected. The slide switch with lock-on keeps your hand comfortable on long jobs. XPT seals internal parts against dust and moisture. Weight is 2.4kg bare.

This is a serious professional tool. The flat head profile sets it apart for access work. It ships with a Makpac carry case and carries a Makita manufacturer warranty.

The Technology Explained

The GA055G uses a brushless motor which has no carbon brushes to wear out giving longer life and better efficiency than brushed motors. It runs on Makita's 40V Max XGT platform at up to 9,000 RPM. The flat head body sits lower than a gear head design making it practical in tight access situations. AFT monitors disc rotation and kills the motor if speed suddenly drops a real-world kickback guard. XPT seals the internals against dust and water. The electric brake stops the disc in a fraction of the time it would take to coast down naturally.

Using It Safely

Always fit the correct guard use a grinding guard for grinding discs and a cutting guard for cutting discs. Check every disc is rated for at least 9,000 RPM before fitting. Use the side handle for two-handed control at all times. Wear eye protection, gloves and hearing protection. The GA055G's electric brake stops the disc fast but wait until it has fully stopped before setting the tool down. The anti-restart feature protects you when swapping batteries but always switch off first.
