DeWalt DCG420 18v XR Cordless Brushless Compact Die Grinder
The DeWalt DCG420 18V XR Cordless Brushless Compact Die Grinder is a professional-grade cordless tool built for metalworking, fabrication, automotive, and maintenance applications.
Powered by an 18V XR brushless motor, the DCG420 delivers improved efficiency, extended runtime, and greater motor longevity compared to brushed alternatives — making it well suited to sustained use on demanding sites and in busy workshops. Its slim, lightweight body allows excellent manoeuvrability in confined spaces, giving tradespeople precise control when grinding, deburring, polishing, or finishing in areas that larger tools simply cannot reach.
Variable speed control lets users dial in the right performance for different materials and tasks, from weld cleaning and surface preparation to detailed metal shaping and finishing work. The textured rubber nose grip aids secure handling during intricate operations, while the optimised airflow system channels air away from the user for improved comfort during prolonged use.
As part of the DeWalt XR cordless platform, the DCG420 integrates with a wide range of compatible 18V batteries, offering genuine freedom of movement without sacrificing professional performance.

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
