Makita DGA504Z 18V LXT Brushless Angle Grinder - 5 Inch Disc And 8,500 RPM Power

Makita DGA504Z 18V LXT Brushless Angle Grinder is built around a 125 mm (5 inch) disc and an 18V lithium-ion platform, giving US users cordless freedom for cutting and grinding steel, stone and concrete on jobsites and in home workshops. With a brushless motor driving up to 8,500 rpm no-load speed and compatibility with Makita 18V LXT batteries, it slots into existing tool kits as a bare tool for metalworkers, fabricators and remodelers who already own chargers and packs.

Brushless Power And 5 Inch Disc Capacity

The DGA504Z uses an 18V LXT lithium-ion battery system and a brushless DC motor designed to deliver a no-load speed of 8,500 rpm for cutting and surface grinding with 125 mm (5 inch) wheels.Makita lists a maximum wheel diameter of 125 mm for depressed center, cut-off and sanding discs with an 18V voltage rating. The grinder is part of Makita's LXT range, working with 18V batteries from 1.5 Ah up to high-capacity packs such as 5.0 Ah and beyond, so owners of existing LXT kits can run it without changing platforms.The official specification lists compatibility with multiple 18V LXT battery sizes.

Makita builds several control features into the DGA504Z to manage that power. Automatic Torque Drive (often shortened to ADT) adjusts torque and speed depending on load, aiming for faster rotation in lighter tasks and higher torque when the wheel is pushed into tougher cuts.Retail descriptions highlight Automatic Torque Drive and soft start as key control features alongside the brushless motor Makita also uses soft-start electronics to bring the disc up to speed more smoothly and an electronic current limiter to protect the motor under overload, a set of features aimed at professional users who lean on grinders for extended periods.

Design, Safety Features And Included Accessories

The DGA504Z is configured as a slide-switch grinder with a lock-on function, rather than a paddle trigger, which suits users who prefer continuous operation when cutting or grinding for longer runs.Retail listings describe a slide switch with a lock-on feature for continuous grinding The housing length is about 362 mm, giving a familiar, compact footprint for a 5 inch grinder, and Makita keeps the grip circumference relatively slim to make one-handed positioning easier around welds and masonry cuts.Makita lists overall dimensions of roughly 362 mm in length with a net tool-only weight around 2.0 kg.

Safety features extend beyond soft start and overload protection. The grinder integrates anti-restart protection to prevent the tool from inadvertently starting when a battery is inserted with the switch left on, and kickback detection can shut the motor down if the wheel abruptly stops in a bind, reducing the risk of the grinder twisting violently in the user's hands.Makita highlights kickback detection, anti-restart and soft start among the headline features Makita's XPT (Extreme Protection Technology) hardens the tool against dust and moisture, an advantage for users who cut concrete and block or work in fabrication shops with airborne metal dust.

Box contents matter to users who already own discs and accessories. Makita and trade listings describe the DGA504Z as a "skin" or body-only tool, meaning it ships without a battery, charger or case, but with essentials for immediate use.Makita lists a 125 mm grinding disc, side grip, tool-less guard and lock nut wrench as included accessories Some kits and retail bundles, such as Makita sets that pair the grinder with a hammer drill, add more accessories or carrying cases, but the core DGA504Z designation refers to the bare grinder with side handle and guard.

Makita Brand, US Entity And Warranty Context

Makita markets the DGA504Z under the Makita brand that US readers recognize from 18V LXT tools on job sites and in retail aisles. In the United States, Makita U.S.A., Inc. in La Mirada, California is the principal sales and distribution entity for power tools, backed by warehouse and training centers in Georgia, Nevada and Texas.Makita USA materials describe the home office at 14930 Northam Street in La Mirada, California, supported by distribution facilities across several states While Makita Corporation is headquartered in Anjo, Japan, US buyers of the DGA504Z interact primarily with Makita U.S.A., Inc. for sales, service and warranty questions.

Warranty support for the DGA504Z follows Makita's standard power tool coverage. A typical arrangement offers a one year warranty that can be extended to three years when the tool is registered online shortly after purchase, provided it is a CE-marked electric tool and not a battery, charger or petrol unit.Retail information notes a one year warranty with the option to extend coverage to three years via Makita registration for eligible tools For US purchasers, warranty claims route through Makita's service network, including factory service centers and area service agents that handle inspection and repair.

Price Positioning And Alternative Grinder Options

Pricing for the DGA504Z bare tool sits in the professional cordless grinder band. A specialist tool retailer lists the 18V DGA504Z 5 inch angle grinder body-only unit at £126.00 including VAT, positioning it as a mid-range professional grinder rather than a budget DIY model.Tool retailers show the DGA504Z priced around the mid-level for professional cordless grinders, reflecting its brushless motor and safety features In US terms, comparable 18V LXT brushless 5 inch grinders from Makita generally fall into the established power tool price band for mid-range cordless grinders where buyers pay for brushless efficiency, electronic protection and platform compatibility.

Within Makita's own lineup, the DGA506Z is a closely related 18V LXT brushless 125 mm grinder with a paddle switch rather than the DGA504Z slide switch.Retail comparisons highlight the DGA506Z as an alternative with the same 125 mm disc and 18V platform but a different switch style A user choosing between the DGA504Z and DGA506Z weighs switch preference and ergonomics more than raw power, because both share the same disc diameter and brushless drive characteristics. Against basic brushed motor grinders, the DGA504Z stands out through brushless design, electronic safeguards and integration into the LXT battery ecosystem.

Use Cases, Limits And Who The DGA504Z Suits

Makita DGA504Z 18V LXT Brushless Angle Grinder is pitched at tradespeople such as fabricators, welders and stone masons who need a compact, cordless 5 inch grinder with serious cutting and grinding capacity.Trade-focused listings describe the DGA504Z as suited to fabricators, engineers, welders and stone masons rather than casual users The combination of brushless motor, 125 mm disc, 8,500 rpm speed and electronic control suits heavy-duty metal cutting, grinding welds and trimming masonry on sites where corded grinders would be inconvenient. Its limitations sit mainly in runtime, which depends on battery capacity, and the fixed 5 inch disc size: users needing larger discs for deep cuts will look at corded 7 inch or 9 inch grinders, while those prioritizing compactness may pick 4.5 inch cordless models.

For US readers already invested in Makita's 18V LXT battery system, the DGA504Z adds a brushless grinder option that works with existing packs and chargers, delivering professional-level control features and dust protection without demanding a platform change. For newcomers, it serves as a solid entry into the LXT system, although they will need to purchase batteries and chargers separately and choose disc types that match the 125 mm capacity and application, from thin cut-off wheels to thicker grinding and flap discs.
