Pro Tool Reviews has published a hands-on assessment of Greenworks’ 24V Pro AG590, a cordless 4 1/2-inch angle grinder priced at $79.97 as a bare tool. The reviewer praised its compact design, three speed settings and tool-free guard adjustment for common cutting and grinding, while noting that it is not the most powerful grinder and has no kit option.
Pro Tool Reviews has published a hands-on review of the Greenworks 24V Pro AG590, a cordless 4 1/2-inch angle grinder that costs $79.97 as a bare tool. The reviewer found it capable of common cutting and grinding work, citing its three speed settings and compact build, while cautioning that it is not the most powerful grinder they have used.
The AG590 uses a brushless motor with three speed selections: 4,500, 6,500 and 9,000 RPM. Pro Tool Reviews says the low, medium and high settings let users match speed to the material, accessory or task. The report presents the simpler three-setting approach as useful for routine work, while noting that some professional variable-speed grinders offer more adjustments for users who need finer control.
In the reviewer’s hands-on test, the tool ground a piece of scrap angle iron without stalling under pressure. The reviewer described its power as adequate for most common work suited to a 4 1/2-inch grinder, but did not characterize it as a top performer for power. That assessment comes from the source reviewer’s test, not from an independently reported comparison or standardized performance test.
The grinder weighs 3.9 pounds without a battery and 5.6 pounds with a 4.0Ah battery, and measures 12 inches long, according to the report. Its listed features include a slim rubber-overmolded grip, a two-position side handle, a tool-free adjustable wheel guard and a removable plastic cutting guard. Wheel changes still require the included spanner wrench to loosen the flange nut after the spindle lock is engaged.
A Lower-Cost Cordless Grinder Option
The AG590’s $79.97 bare-tool price places it as a lower-cost option for people considering a cordless grinder, particularly those who already own batteries in Greenworks’ 24V system. Existing users can add the tool without buying another battery and charger, although the source does not provide a total cost comparison with competing grinders or battery bundles.
For professional users, the review points to a practical mix of portability and basic control rather than a claim of best-in-class output. The three speed levels may suit common repair, cutting and surface-preparation tasks, while the reviewer’s caveat about power and the lack of finer speed adjustments matters for demanding or highly controlled fabrication work. Buyers should match the tool’s capacity to the job and use compatible accessories and guards.

Greenworks’ 24V Pro Tool Line
The source report says Greenworks introduced a new 24V tool line aimed at professional users during the year before the review. Pro Tool Reviews says its reviewers tested tools from the line against professional-grade equipment they use, then focused this report on the AG590 and metalworking applications. The material does not state the exact launch date or provide a full platform-wide comparison.
The AG590 sits above Greenworks’ single-speed DIY-oriented AGD401 in feature set, according to the review. The writer says the Pro model adds three speed settings and that components were upgraded for longer working hours and tougher jobsite conditions. These are descriptions in the review; the supplied source does not include independent durability testing or component specifications.
The reported price is for the bare tool, and the reviewer says Greenworks does not offer the AG590 as a kit. The grinder is compatible with Greenworks 24V batteries. The report also notes a retail connection to Walmart, including delivery availability that can vary by location; it does not establish current stock or delivery times for every buyer.
“The power level was absolutely perfect.”

Limits of the Available Testing
The supplied report does not give a publication date, current retailer inventory, or confirmation that the $79.97 price remains available. It also does not provide standardized tests, long-term durability results, runtime figures, or detailed head-to-head performance data against competing models. The reviewer’s account of grinding angle iron is a hands-on observation, not a controlled test across multiple materials and workloads.
The report says the tool is intended for longer hours and tougher conditions than the basic DIY model, but the supplied material does not document how the AG590 performs over an extended jobsite trial. Buyers also need to confirm that their Greenworks 24V batteries and chosen accessories are appropriate for the task; the review does not list battery runtime or accessory-specific limits.
Check Price and Platform Fit
People considering the AG590 can check current retailer listings for price and availability, then compare the bare-tool cost with the expense of entering Greenworks’ 24V battery platform if they do not already own compatible batteries. The source report names no future product announcement, scheduled test or follow-up review, so there is no confirmed next milestone in the supplied material.
Before buying, users should verify that the grinder’s three speed settings, 4 1/2-inch format and reported power suit their intended work. They should also account for the absence of a kit option and review the manufacturer’s instructions for the tool, battery, wheel and guards.
