Angle Grinder DeWalt DCG404NT 18V, 125 mm wheel, brushless motor, TSTAK compatible

The DeWalt DCG404NT 18V angle grinder is a cordless tool engineered for cutting, grinding and surface preparation with 125 mm discs. Its brushless motor improves efficiency and reduces maintenance compared with brushed designs, while the 18V platform offers portability for job sites and renovation tasks. Supplied as a bare tool (battery and charger not included), the grinder is compatible with TSTAK storage systems to keep accessories and spare batteries organised.

Advantages

The brushless motor delivers longer run-time and increased motor life compared with traditional brushed motors. The 125 mm wheel size balances cutting/grinding capacity with manoeuvrability for work in confined areas. Cordless operation on the 18V platform removes the need for extension cords and allows faster repositioning on site. Compatibility with TSTAK storage helps maintain an orderly workshop or site van and simplifies transport of the tool and accessories.

Suitable for

• Cutting metal pipes, rods and profile sections with 125 mm discs
• Grinding welds, removing rust and smoothing metal surfaces
• Masonry tasks such as light cutting or surface preparation on bricks and blocks
• On-site repair, renovation and maintenance where cordless freedom is required

When it may not be suitable

This bare tool is supplied without battery and charger, so buyers who do not already have compatible 18V batteries will need to purchase them separately. For heavy industrial applications requiring continuous high-power use or larger discs, a higher-voltage or corded angle grinder with a bigger wheel (e.g. 230 mm) may be more appropriate.

Key specifications

• Voltage: 18 V (cordless platform)
• Disc diameter: 125 mm
• Motor type: brushless (brushless DC)
• Intended applications: cutting, grinding, surface preparation on metal and masonry
• Storage compatibility: TSTAK system compatible
• Tool supply: bare tool (battery and charger not included)

How to use

Fit an appropriate 125 mm disc for the intended task and ensure the disc is rated for the grinder's maximum speed. Secure the side handle in a comfortable position and wear recommended personal protective equipment including eye, ear and respiratory protection and cut-resistant gloves. Install a compatible 18V battery and check the tool's guard is correctly positioned before starting. Use controlled, steady pressure without forcing the disc; allow the tool to reach full speed before contacting the workpiece and maintain a firm two-handed grip while operating.

What to consider before purchase

• Whether you already own compatible 18V batteries and charger for cordless operation
• The types of discs required (cutting, grinding, masonry) and their maximum speed ratings
• Frequency and intensity of use — occasional site jobs versus continuous industrial use
• Need for TSTAK-compatible storage to organise the tool and accessories

Usage recommendations

For effective and safe operation, use discs rated for 125 mm and the grinder's maximum RPM, replace worn discs promptly, and follow manufacturer guidelines for battery care. Store the tool in a TSTAK case to protect it during transport and keep spare batteries charged and available for uninterrupted work periods.
