The grinder is part of Makita's LXT cordless range, working with 18V batteries from compact 1.5 Ah packs up to high-capacity cartridges such as 5.0 Ah and above.Makita's regional technical listing notes compatibility with a wide span of 18V LXT batteries including 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah, 5.0 Ah and higher-capacity packs.
Size, Layout And Safety Features
The DGA504Z is configured as a slide-switch grinder with a lock-on function rather than a paddle trigger, giving continuous on control for extended grinding passes once the wheel is up to speed.A major UK retailer describes the DGA504Z as a cordless angle grinder with a slide switch designed for one-hand operation and continuous grinding.
Makita builds the tool around a compact housing approximately 362 mm in length with a height close to 145 mm and a width near 140 mm, keeping the grip circumference manageable for welding, pipe cutting and masonry work.A detailed retail specification lists the DGA504Z at 362 mm in length, 145 mm in height and 140 mm in width with a 125 mm maximum disc diameter.
On the safety side, documentation for the DGA504Z highlights an electric brake and electronic current limiter designed to stop the wheel quickly and protect the motor under overload.A user manual summary notes an electric brake that stops the wheel in around two seconds and an electronic current limiter for overload protection.

Positioning Against Other 5 Inch Cordless Grinders
Compared with many 4.5 to 5 inch cordless angle grinders that run between 8,000 and 9,000 rpm, the DGA504Z sits squarely in the mainstream performance band with its 8,500 rpm rating, while offering Makita's brushless efficiency and electric brake safety features.The user manual summary highlights both an 8,500 rpm no-load speed and an electric brake for quick wheel stopping, features that place the tool alongside other modern brushless grinders.
Its ability to run standard 125 mm discs on the widely adopted 18V LXT platform means owners of other Makita tools can consolidate chargers and batteries, while the slide switch layout appeals to users who favor lock-on operation over momentary paddle triggers for cutting and grinding tasks that last more than a few seconds.Makita notes the DGA504Z as a slide-switch model within the broader LXT family, using the same 18V battery cartridges as other cordless tools.
