Makita 4″ 40V Cordless Angle Grinder GA021GZ (Body Unit) | Model : M-GA021GZ

The Makita 40V Angle Grinder GA021GZ is a high-performance cordless tool designed for professional grinding and cutting applications. Makita built this grinder using advanced technology to deliver strong performance, improved safety, and better productivity for demanding work environments.

This cordless grinder runs on Makita’s 40V XGT battery platform, which provides powerful performance without the limitations of a power cord. The Makita 40V Angle Grinder supports a 100 mm (4 inch) wheel diameter, making it ideal for metal grinding, cutting, polishing, and surface preparation tasks.

The grinder features a variable no-load speed range of 3,000 to 8,500 RPM. This speed control allows users to adjust the tool according to different materials and applications. The high-speed capability ensures efficient cutting and smooth grinding results.

Makita includes Active Feedback Sensing Technology (AFT) in this grinder. This safety feature automatically turns off the motor if the rotation speed suddenly slows or if the wheel stops unexpectedly. This function protects both the operator and the tool during operation.

Another advanced feature of the Makita 40V Angle Grinder is the Auto-Start Wireless System (AWS). This system connects the grinder to compatible vacuum cleaners using Bluetooth technology. When the grinder starts, the vacuum automatically activates to remove dust and debris. This feature helps maintain a cleaner and safer workspace.

Makita also designed this grinder with a toolless wheel cover system. Users can adjust or install the wheel cover quickly without using additional tools. This saves time and improves convenience during work.

The grinder also includes an electric brake, which stops the wheel quickly after the tool turns off. This feature increases productivity and improves safety during frequent grinding operations.

The Makita 40V Angle Grinder GA021GZ measures 413 × 117 × 150 mm with BL4025 battery and 425 × 117 × 162 mm with BL4040 battery. The tool weighs between 2.8 kg and 3.4 kg, depending on the battery used. This balanced design provides stability while maintaining comfortable handling.
