Makita DGA504Z 18V Angle Grinder - 8,500 RPM and 5-Inch Disc

Makita DGA504Z 18V LXT Brushless Angle Grinder is a cordless 5-inch tool for cutting, grinding, and sanding. Its brushless motor reaches 8,500 rpm without a load, while the 18V LXT battery platform removes the power cord from metalworking and repair tasks.

Core Grinder Specifications

The DGA504Z accepts depressed-center, cut-off, and sanding discs with a maximum diameter of 125 mm, equivalent to 5 inches. Makita lists an overall length of 362 mm and a tool-only net weight of 2.0 kg on its model specification.

The grinder uses a slide switch with lock-on operation. Kickback detection, anti-restart protection, soft start, automatic torque drive, and an electronic current limiter are listed among its operating and safety features.

Battery And Box Contents

The DGA504Z is a bare-tool configuration rather than a complete cordless kit. The listed package includes a 125 mm grinding disc, side grip, tool-less guard, and lock nut wrench; the battery and charger are sold separately.

Compatibility covers Makita 18V LXT lithium-ion batteries. The model specification lists battery capacities from 1.5 Ah through 12 Ah, allowing the same grinder body to use packs from the broader LXT system.

Position Among Cordless Grinders

Compared with a corded 5-inch grinder, the DGA504Z trades continuous wall power for battery operation and platform compatibility. Compared with Makita's newer 18V grinder designs, its 8,500 rpm ceiling and slide-switch layout define a straightforward cutting and grinding setup.

The tool-only format has a specific economic logic: buyers who already own an 18V LXT battery and charger avoid duplicating those components. A new user must add both power components, so a kit version or corded grinder can be a better category comparison.

Best Fit For Workshop Tasks

The Makita DGA504Z fits metalworkers, fabricators, remodelers, and advanced do-it-yourself users who already use Makita 18V LXT batteries. Its 125 mm disc capacity covers common grinding, cutting, and sanding accessories, while its 362 mm length gives the tool a compact format for handheld work.

Its main limits are the bare-tool package, the fixed 8,500 rpm no-load speed, and the need for compatible 18V LXT batteries. The model is best understood as a platform grinder for users with existing Makita battery equipment, not as a complete starter kit.
