Greenworks releases budget friendly angle grinder
Greenworks releases budget friendly angle grinder with brushless motor and three speed settings for professionals.

Greenworks has released a new line of 24V tools, including the Greenworks 24V Pro 4 1/2-Inch Angle Grinder AG590, aimed at professionals who want high-quality tools without the high price tag. The AG590 features a brushless motor with three speed settings: 4,500, 6,500, and 9,000 RPM, giving users more flexibility when working with different materials and accessories.
While some variable-speed models have more available settings, the AG590’s simpler low/medium/high interface makes it easier to use for basic cutting and grinding tasks.
Notably, the three-speed design is one of the more notable upgrades over their more basic single-speed DIY-focused grinder (AGD401), providing added control when switching between grinding and cutting applications or when working with accessories or materials that call for different speeds.
Performance and Design
During hands-on testing, the AG590’s power level was found to be perfect for most common cutting and grinding tasks, and it was able to handle a scrap piece of angle iron with a grinding disc without stalling the motor. The tool weighs 3.9 pounds as a bare tool and 5.6 pounds with a 4.0Ah battery, and its compact design makes it comfortable to grip and use.
The AG590 has a tool-free adjustable wheel guard, which is a must-have feature for any professional-focused grinder, and it also comes with a removable plastic cutting guard for added safety. The wheel change process is straightforward, and the included spanner wrench makes it easy to loosen the flange nut.
Interestingly, the AG590’s specs are very similar to the DeWalt Atomic DCG402, which is already a very small angle grinder, and it is nearly identical to the ADG401, but the added bonus of the variable speed modes makes this a far more advantageous option.
The Greenworks 24V Pro Angle Grinder retails for $79.97 as a bare tool and comes with a 5-year warranty, making it a remarkable value for a competent tool. The price is especially appealing for those who already own Greenworks 24V batteries, as they can add the AG590 to their arsenal without having to purchase another battery and charger.
The AG590’s features, including its three-speed settings, tool-free guard adjustment, and two-position side handle, make it a versatile option for general cutting and grinding work. Its compact design and affordable price make it an attractive option for professionals who want a high-quality tool without breaking the bank. The Greenworks 24V Pro Angle Grinder is compatible with all Greenworks 24V batteries, making it a convenient addition to any existing toolkit.
The writer found the ergonomics of the angle grinder to be comfortable, with a slimmer handle that makes it easier to grip, particularly for those with small to medium-sized hands. The lightly textured rubber overmold also helps absorb some of the vibration generated during grinding and cutting.
The AG590 has a 2-position side handle that can be quickly configured to fit the user’s preferences and workflow.
The AG590’s price point and feature set make it a worthwhile consideration for those looking for a capable cordless grinder without breaking the bank.
