Makita GA4030 4-Inch Angle Grinder - Lightweight Power and Precision

Overview

Meet the Makita GA4030, a compact 4-inch angle grinder built for jobs that demand comfort, control, and reliable performance. It features a barrel grip of 2-1/4 inches - the smallest in its category - and weighs about 3.1 pounds. The result is a tool that feels easy to maneuver even in tight spaces and helps you stay precise as you work.

Design and durability that matter

Makita equips the GA4030 with labyrinth construction and zig-zag varnish to seal the motor and bearings against dust and debris. This approach can extend tool life and reduce maintenance in challenging environments, so you can keep going between setups.

Additionally, the side handle is set at a 20-degree angle, and the grip remains comfortable through longer sessions, which can help you maintain better control during grinding, cutting, or beveling tasks.

Performance at a glance

The grinder is powered by a 6.0-amp motor that reaches up to 11,000 RPM, delivering the speed needed for metalworking, prep, and material removal. While it is not a heavy-duty industrial machine, its blend of power and portability makes it a versatile option for a wide range of projects.
