Angle Grinder DeWalt DCG404N, 18V, 125 mm disc (battery not included)

DeWalt DCG404N is a cordless angle grinder designed for use with 125 mm discs on an 18V platform. Supplied as a bare tool (battery and charger not included), this model provides cordless mobility for jobs that require cutting, grinding or surface preparation on metal and masonry. The compact design and compatibility with standard 125 mm accessories make it suitable for professional and DIY applications where portability and straightforward handling are important.

Advantages

The DCG404N combines a brushless motor architecture with an 18V battery platform to deliver efficient power and longer runtime compared with brushed alternatives when paired with compatible batteries. Its 125 mm disc capacity balances cutting and grinding performance with a compact form factor, while the bare-tool format allows users to integrate the grinder into existing DeWalt battery ecosystems. The tool’s ergonomic body and auxiliary handle options support controlled operation during prolonged tasks.

Suitable for

• Cutting metal pipes, rebar and sheet metal with 125 mm cutting discs
• Grinding welds, removing rust and burrs from metal surfaces
• Masonry cutting and tuckpointing with appropriate discs
• Surface preparation prior to painting or coating
• Portable workshop and on-site renovation tasks where cordless operation is preferred

When it may not be suitable

This bare tool is supplied without battery and charger, so it is not ready-to-use unless compatible DeWalt 18V batteries and a charger are available separately. For heavy-duty industrial cutting where larger discs (greater than 125 mm) or sustained high-power operation are required, a larger grinder or mains-powered unit may be more appropriate.

Key specifications

• Power system: 18V cordless (battery sold separately)
• Disc diameter: 125 mm
• Motor type: brushless
• Primary uses: cutting, grinding, surface preparation
• Form factor: handheld angle grinder with auxiliary handle mounting options

How to use

Fit a compatible 125 mm disc according to the disc manufacturer’s instructions and ensure the guard is correctly positioned before switching on. Secure the auxiliary handle in the preferred position for better control. Insert a charged DeWalt 18V battery and verify it is locked in place. Operate the grinder with steady pressure, allowing the disc to perform the work without forcing it. After use, switch off the tool and remove the battery before changing discs or performing maintenance.

What to consider before purchase

• Battery and charger are not included; confirm compatibility with DeWalt 18V batteries you already own or plan to buy
• Choose appropriate 125 mm discs for the intended material (metal, masonry, abrasive grinding)
• Verify that brushless motor and 18V platform meet your runtime and power requirements for typical tasks

Usage recommendations

Use protective equipment including eye protection, gloves and hearing protection. Match disc type to the material and inspect discs for damage before each use. Allow the tool to cool during extended heavy use and follow the manufacturer’s maintenance guidelines to ensure safe and reliable operation.
