Pro Tool Reviews tested Greenworks’ AG590, a cordless 4 1/2-inch angle grinder for the company’s 24V Pro line. The review reports three speed settings, a brushless motor and a $79.97 bare-tool price, while noting there are no kit options. Its performance assessment comes from the reviewer’s hands-on testing, not independent comparative testing.
Pro Tool Reviews has published a hands-on report on Greenworks’ AG590, a cordless 24V Pro 4 1/2-inch angle grinder priced at $79.97 as a bare tool. The reviewer found it capable of common cutting and grinding tasks during testing, while the report notes that buyers cannot purchase it as a kit with a battery and charger.
The AG590 has a brushless motor and three speed settings: 4,500, 6,500 and 9,000 RPM. Pro Tool Reviews says the selectable speeds let users match the grinder more closely to the task, accessory or material. The review contrasts the three-setting control with the single-speed Greenworks AGD401, while noting that some professional models offer more speed selections.
In the reviewer’s test, the grinder handled a scrap piece of angle iron with a grinding disc without stalling. The reviewer described its power as sufficient for most common work suited to a 4 1/2-inch grinder, but said it was not the most powerful grinder they had used. That is a hands-on assessment; the supplied report does not provide standardized performance measurements or a direct test against competing models.
The bare tool weighs 3.9 pounds, according to the report, and weighs 5.6 pounds with a 4.0Ah battery. It measures 12 inches end to end. Other listed features include a slim, textured handle, a tool-free adjustable wheel guard, a removable plastic cutting guard, a two-position side handle and compatibility with Greenworks 24V batteries. Wheel changes use a spindle lock and the included spanner wrench.
A Lower-Cost Entry to Cordless Grinding
The AG590’s main appeal, as presented in the review, is its combination of variable speed, a brushless motor and a sub-$80 bare-tool price. That could matter to people already using Greenworks 24V batteries, who can add the grinder without buying another battery and charger. For new customers, the low listed tool price may make the platform less expensive to try, but the cost of batteries and a charger would need to be counted separately.
Tool-free guard adjustment and the included cutting guard also speak to practical use across cutting and grinding tasks. The report describes the AG590 as a candidate for general work, not a replacement for every higher-powered or more finely adjustable grinder. Its value will depend on the demands of the job, the user’s existing battery setup and whether three speed options are enough.

Greenworks’ 24V Pro Tool Line
Pro Tool Reviews places the AG590 within Greenworks’ newer 24V Pro line, which the report says is aimed at professionals seeking lower-cost tools. The article compares the AG590 with Greenworks’ more basic AGD401, identifying the three speed modes as a key difference. It also says the Pro-line components were upgraded to handle longer hours and tougher work environments, a statement about the product line that is not accompanied by component specifications in the supplied material.
The review lists a five-year warranty and says the grinder is sold for $79.97 without battery or charger. It reports no kit options. The source also mentions Walmart as a retail connection and says delivery may be available in less than an hour in some locations; availability will depend on location and is not established for every buyer.
“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.”

Test Scope and Ownership Costs
The supplied report does not give a publication date, a full test protocol, measured cutting rates, runtime figures or results from long-term use. Its performance conclusions are based on the reviewer’s described hands-on experience, so readers do not have a standardized comparison with other grinders in this material.
The $79.97 figure is for the bare tool. The source does not state the cost of compatible batteries and chargers, nor does it establish current inventory or delivery times across retailers. It also does not detail warranty exclusions or conditions. Buyers should check the current listing and warranty terms before purchasing.
Check Local Pricing and Availability
The report does not announce a future product launch, test update or company event. For prospective buyers, the next step is to check Greenworks’ current product and warranty information and confirm local stock and pricing. Customers who do not already own a compatible Greenworks 24V battery should compare the total cost of the tool, battery and charger with bundled alternatives.
Further testing that reports runtime, cutting speed and performance across materials could help establish how the AG590 compares under repeatable conditions. No such follow-up results are included in the supplied source.
