Pro Tool Reviews evaluated Greenworks’ AG590, a 24V cordless angle grinder priced at $79.97 as a bare tool. The review highlights its brushless motor, three speed settings and tool-free guard adjustment, while noting that it is not a kit and offers less speed control than some professional models.
Pro Tool Reviews has published a hands-on review of the Greenworks 24V Pro AG590, a cordless 4 1/2-inch angle grinder priced at $79.97 as a bare tool. The assessment describes a compact, brushless model with three speed settings and a five-year warranty, aimed at buyers who want a lower-cost option for common cutting and grinding work.
The AG590’s brushless motor offers three speeds: 4,500, 6,500 and 9,000 RPM. Pro Tool Reviews says the settings provide a straightforward way to adjust operating speed for different tasks and accessories. The reviewer found the grinder had enough power for a test grinding scrap angle iron and did not stall during that work, while cautioning that it is not the most powerful grinder they have used.
The review lists the tool at 3.9 pounds without a battery and 5.6 pounds with a 4.0Ah battery. It measures 12 inches end to end. The reviewer praised the slim handle and textured rubber overmold, describing the grip as comfortable, particularly for users with small to medium-sized hands. A two-position side handle can be set to suit the user’s grip or work position.
Other features include a tool-free adjustable wheel guard and a removable plastic cutting guard supplied for additional protection during cutting. Wheel changes require pressing the spindle lock and using the included spanner wrench to loosen the flange nut. Greenworks says the AG590 works with its 24V batteries. The source reports a five-year warranty, but says no battery-and-charger kit option is available.
A Lower-Cost Cordless Grinder Option
The reported $79.97 bare-tool price makes the AG590 relevant to tradespeople and other users looking to add a cordless grinder without paying for another battery and charger. Its value is clearest for people who already own compatible Greenworks 24V batteries; buyers new to the platform need to account for the battery and charger separately because the review says the grinder is not sold in a kit.
Its features also place the tool between a basic single-speed grinder and models offering finer electronic speed adjustment. The three settings may be enough for routine cutting and grinding, as the reviewer argues, but they provide less control than some professional grinders with more settings. The assessment is a useful comparison point for shoppers, not a guarantee that the tool will suit every material, accessory or sustained work demand.

Greenworks’ 24V Pro Tool Line
The review places the AG590 within Greenworks’ newer 24V Pro lineup, which the source describes as intended for professionals seeking less expensive tools. Pro Tool Reviews compares it with Greenworks’ AGD401, a more basic, single-speed grinder, and says the AG590 adds three speed modes. It also notes that Greenworks says components in the Pro line were upgraded to handle longer hours and tougher work environments; that characterization comes from the product development claims cited in the review.
For comparison, the reviewer says many variable-speed professional grinders offer a broader range of settings, including dial-based adjustment or five-mode selection. The AG590’s simpler low, medium and high approach is presented as easier to use for common tasks, while offering less precision for fabrication work where fine speed tuning may be useful. The review also notes that the tool’s size and weight are similar to DeWalt’s Atomic DCG402, but that comparison does not establish equivalent performance.
“I was able to bear down on a scrap piece of angle iron with a grinding disc without any issues and never managed to stall the motor.”

Limits of the Review Evidence
The source provides a reviewer’s hands-on account, not a standardized head-to-head test with published measurements for cutting speed, runtime, vibration or durability. It does not specify how long the grinder was tested, which battery was used for the metalworking test, or how it performs under extended professional workloads. The reviewer’s favorable result on scrap angle iron should not be read as confirmation that the tool matches more expensive grinders across all applications.
The reported price and availability may change, and the source does not provide a date-specific retailer listing or confirm current stock. It identifies no kit option, but does not give the separate cost of a compatible battery and charger. Buyers should check the current listing, warranty terms and accessory compatibility before purchasing.
Check Price and Battery Fit
No follow-up test or company announcement is included in the source material. For prospective buyers, the next practical step is to confirm the current price, stock and warranty terms, then check whether they already own a compatible Greenworks 24V battery. Those starting without one should compare the total cost of the tool, battery and charger with bundled options from competing cordless platforms.
Users should also match the grinder’s speed and accessories to the work they plan to do, and follow the manufacturer’s instructions for guards and wheel changes. The review supports considering the AG590 for common 4 1/2-inch grinding and cutting jobs; it does not settle how it will perform in specialized fabrication or sustained heavy-duty use.
