New Affordable Angle Grinder Enters the Market with Pro-Grade Features
Greenworks has expanded its 24V Pro tool lineup with a new cordless angle grinder designed to deliver solid performance without the premium price tag typical of established brands. The AG590 model combines practical features and competitive pricing, making it an attractive option for homeowners and tradespeople looking to add a reliable cutting and grinding tool to their arsenal.
What Makes This Angle Grinder Stand Out

The AG590 features a brushless motor with three selectable speed settings: 4,500, 6,500, and 9,000 RPM. This tiered approach provides flexibility for different materials and applications without overwhelming users with excessive options. Lower speeds work well for precision tasks requiring finesse, while the maximum setting handles faster material removal when you need to work more quickly.
Compared to Greenworks’ single-speed DIY model, the variable-speed design represents a meaningful upgrade. While some professional competitors offer dial controls with dozens of micro-adjustments or five-mode electronic selection, the simple low-medium-high interface suits most common cutting and grinding jobs without unnecessary complexity. For general metalworking, repairs, and surface preparation, this straightforward speed control actually improves usability for typical tradespeople.
Power delivery is another strength. Field testing showed the motor can handle sustained grinding pressure on metal without stalling, delivering adequate performance for 4.5-inch wheel applications. While not the most powerful grinder available, it handles the majority of tasks homeowners and professionals encounter regularly.
Design and Ergonomic Considerations
At 3.9 pounds as a bare tool and 5.6 pounds with a 4.0Ah battery, the AG590 maintains a compact, lightweight profile similar to the DeWalt Atomic DCG402. The slim handle design improves comfort for users with small to medium-sized hands, and the lightly textured rubber grip helps absorb vibration during extended use.
Tool-free guard adjustment stands out as a practical feature. Rather than hunting for a special wrench, you simply release a tensioning lever to reposition the guard for different cutting or grinding tasks. This convenience matters when switching between applications multiple times during a job. The package includes both a standard grinding guard and a removable plastic cutting guard for added safety versatility.
Wheel changes use a straightforward spindle lock system. Press down the lock, rotate by hand until it engages, then use the included spanner wrench to loosen the flange nut. Greenworks also provides a two-position side handle for quick workflow customization based on your preference and task requirements.
Price and Battery Compatibility Make This Worth Considering
At $79.97 for the bare tool, the AG590 delivers exceptional value. The 5-year warranty provides confidence in durability. More importantly, if you already own Greenworks 24V batteries, you can add this grinder to your collection without purchasing another battery and charger system, keeping your total investment low.
Even if you’re new to the Greenworks platform, the pricing makes entry more affordable than competing brands. Premium manufacturers like DeWalt occasionally offer special promotions with battery bundles, but Greenworks maintains consistently lower baseline pricing without requiring promotional timing.
Distribution through Walmart provides additional convenience. Depending on your location, you can arrange delivery in under an hour, including any accessories needed for your projects. No kit options are currently available, but since angle grinders typically aren’t entry-point tools for most cordless platforms, buying the bare tool separately makes sense for most users.
How It Compares to Premium Brands

Milwaukee and Makita anchor their small angle grinder lines with models supporting 4.5-inch or 5-inch wheels, offering more power and often higher maximum speeds. These premium options deliver noticeable performance advantages and frequently appear in promotional bundles, but cost significantly more in both tool and system pricing.
When comparing the AG590 directly to other dedicated 4.5-inch models, power delivery is competitive. The main difference is top-end speed on some alternatives, which can accelerate material removal. The tradeoff is straightforward: those tools cost more than twice as much. For the majority of homeowners and tradespeople, the Greenworks performance level matches their actual needs.
What This Means for Your Next Project
The AG590 represents a genuine shift in the budget angle grinder category. Rather than cutting corners on features, Greenworks incorporated meaningful upgrades like variable speed, tool-free guard adjustment, and upgraded internal components for professional durability. The combination of features and price makes this worth serious consideration if you’re shopping for a cordless angle grinder without wanting to commit significant budget.
For existing 24V platform users, the decision becomes even simpler. The ability to use your current batteries and charger makes this a straightforward addition to your tool collection. As tool manufacturers continue expanding their affordable pro-level offerings, shoppers have more options than ever to build capable systems without premium spending.
