Weighing 2.4 kg, it is built for portability and single-handed handling in a variety of jobsite and workshop conditions. The tool is available in metallic, blue and black finishes to suit different preferences.

Advantages

The DGA506Z provides high rotational speed for efficient material removal while remaining lightweight for reduced operator fatigue. Its cordless 18V platform ensures freedom of movement and compatibility with a broad range of Lithium-Ion batteries. Compact dimensions allow access to confined spaces and better control during precision grinding and cutting operations. The 125 mm disc size is a common standard, offering a wide selection of abrasive and cutting wheels for different applications.

How to use

Fit a compatible 125 mm disc with a 22.2 mm bore and secure it according to the wheel manufacturer’s instructions and Makita’s fitting procedure. Ensure a charged 18V Lithium‑Ion battery is installed and the grinder’s guards are correctly positioned before operation. Hold the tool firmly with both hands when possible, position the wheel at the correct angle to the work surface, and operate at steady, controlled passes. Allow the disc to reach full speed before contacting the workpiece and avoid excessive side pressure on cutting discs. After use, switch off the tool, wait for the disc to stop completely, and remove the battery before changing accessories or performing maintenance.

Usage recommendations

Use abrasives and cutting wheels rated for 125 mm diameter and 22.2 mm bore. Match wheel type to the task (cutting, grinding, wire brushing, masonry) and follow safety guidelines: eye and hearing protection, gloves, and appropriate clothing. For extended work, select batteries with sufficient capacity and observe manufacturer guidance for cooling and duty cycles to prolong tool and battery life.
