DEWALT 18V XR Brushless 125mm Angle Grinder - Tool Only, DCG407N-XJ

Overview

Take on demanding cutting, grinding and surface-preparation jobs with the DEWALT DCG407N-XJ 18V XR Brushless 125mm Cordless Angle Grinder, a professional-grade grinder designed around DEWALT’s established 18V XR battery platform.

Built with an efficient brushless motor, the DCG407 is designed to deliver strong cordless performance while reducing the maintenance associated with conventional carbon-brush motors. Its compact body, rubber-overmoulded grip and two-position side handle make it suitable for fabrication, installation, automotive, maintenance and construction work where mobility and control are important.

The grinder accepts discs up to 125mm in diameter and operates at a no-load speed of 9,000rpm, providing the speed required for a wide range of compatible grinding and cutting accessories. The spindle uses the common M14 thread, with a disc bore of approximately 22.23mm.

Safety and control are central to the DCG407 design. DEWALT equips the grinder with an Electronic Clutch, which helps reduce the kickback reaction if the accessory becomes pinched or stalls. DEWALT’s current product information also describes an electronic brake and kickback-brake functionality designed to react quickly when the disc is obstructed.

The motor is protected by mesh debris covers that help restrict larger dust and debris particles from being drawn through the tool. This is particularly useful in environments where metal particles and grinding dust would otherwise place additional stress on the motor and internal components.

A robust metal gear housing, rubber grip and repositionable auxiliary handle are designed for demanding site use, while the included grinding and cutting guards allow the tool to be configured for different applications.

This N-XJ version is supplied as a bare tool. No battery, charger, grinding disc or TSTAK case is included. It is intended primarily for users who already own compatible DEWALT 18V XR batteries and chargers.
