Design and Ergonomics
The design of an angle grinder significantly impacts user experience, and both models excel in this area.

In terms of motor performance, the Angle Grinder Cordless for Mwkee M-18 boasts a brushless motor that achieves a remarkable maximum speed of 8500 RPM. This feature enhances its energy efficiency and overall grinding performance. On the other hand, the Milwaukee 2880-20 utilizes a brushless motor as well, but specific RPM figures are not provided. Instead, it includes an electronic clutch for kickback protection and overload protection to maximize motor life, making it a reliable choice for demanding tasks.
Speed Settings and Versatility
The Angle Grinder Cordless for Mwkee M-18 offers three speed settings ranging from 3000 RPM to 8500 RPM, providing versatility for various tasks such as metal cutting, rust removal, and wood polishing.
