Product Description

Makita DGA504 18V Brushless 125mm Angle Grinder (Skin)

The Makita DGA504 18V Mobile 125mm Angle Grinder offers exceptional cordless cutting and grinding performance for professional metalworkers, fabricators, and construction teams. Built around a highly efficient Brushless DC motor, this 125mm (5-inch) grinder eliminates the friction and heat of carbon brushes, resulting in a significantly longer operational lifespan, cooler running temperatures, and extended battery runtime per charge.

Engineered to adapt to the demands of the job, the DGA504 features Makita's innovative Automatic Torque Drive technology. This intelligent system automatically adjusts the cutting speed and torque according to the load condition, ensuring optimal power delivery whether making light cuts or grinding heavy steel. With a no-load speed of 8,500 rpm and robust electronic safety features, it provides a highly reliable, cord-free alternative to traditional mains-powered grinders.

Ideal For:

Metal Fabrication: Cordless freedom for cutting steel profiles, grinding welds, and surface preparation.
Construction & Masonry: Ideal for cutting rebar, concrete mesh, and scoring tiles on remote worksites without power access.
Facility Maintenance: A versatile, highly mobile tool for executing emergency repairs safely and efficiently.

Key Features and Safety Systems:

Brushless Motor Technology: Delivers superior power efficiency, reducing battery drain and completely eliminating brush replacement maintenance.
Automatic Torque Drive: Automatically increases torque to power through tough materials, preventing the disc from bogging down.
Kickback Detection & Anti-Restart: Automatically shuts down the tool if the rotation speed suddenly drops (disc binds), protecting the operator from dangerous kickback. The anti-restart function prevents accidental start-up if the battery is inserted with the switch locked on.
Extreme Protection Technology (XPT): Advanced internal channeling protects the motor and electronics from ingress of abrasive metal dust and moisture.
Electronic Current Limiter: Protects the motor from overload during heavy, sustained grinding applications.

Frequently Asked Questions

What does 'Skin Only' mean for this product?

Skin only means the package includes the DGA504 Angle Grinder tool itself and standard accessories (guard, handle, wrench), but does NOT include the 18V battery or charger. These must be purchased separately or used from your existing Makita LXT kit.

What is the advantage of a Brushless motor?

A brushless motor operates without physical carbon brushes, eliminating mechanical friction. This results in less heat generation, greater power efficiency, longer battery runtime, and a motor that requires zero maintenance.

What is Automatic Torque Drive?

This technology detects the resistance on the grinding disc. If you push hard into thick steel, the tool automatically lowers the speed and increases the torque to power through the cut without stalling.

What size discs does this grinder use?

The DGA504 accommodates standard 125mm (5-inch) cutting, grinding, and flap discs with a standard 22.23mm bore.

What is 'Kickback Detection'?

If the cutting disc gets pinched or binds suddenly in the material, the internal sensors instantly cut power to the motor. This prevents the grinder from violently kicking back out of the cut and injuring the operator.

How does the Anti-Restart function work?

If the slide switch is accidentally left in the 'ON' position while you slide a fresh battery into the tool, the grinder will not start. You must turn the switch off and on again, preventing unexpected and dangerous start-ups.

Does it have a soft start feature?

Yes. Soft start slowly ramps up the speed of the motor when turned on, preventing a sudden, forceful jerk in your hands and ensuring better initial control.

Can this be used for cutting masonry or tiles?

Yes. When fitted with the appropriate continuous or segmented 125mm diamond blade, it is highly capable of cutting brick, concrete, and ceramic tiles.

What type of switch does it have?

This specific model features a top-mounted slide switch that can be locked into the 'ON' position for continuous grinding tasks.

Are the guard and side handle included?

Yes, it is supplied with a tool-less adjustable wheel guard, a side grip handle, a lock nut wrench, and one 125mm grinding disc.

Will my 18V 3.0Ah battery work with this?

Yes, it is compatible with Makita 18V LXT batteries ranging from 3.0Ah up to 6.0Ah. However, higher capacity batteries (5.0Ah or 6.0Ah) are recommended for heavy grinding tasks to provide adequate runtime.

Does it have protection against metal dust?

Yes, it features Extreme Protection Technology (XPT) and wire mesh intake covers to prevent sharp metal filings and dust from damaging the internal electronics.
