Cordless Angle Grinder DeWalt DCG404S2T-QW 125mm, 18V XR, 2×3.5Ah, COMPACT

The DeWalt DCG404S2T-QW 125mm, 18V XR COMPACT cordless angle grinder is a battery-powered tool designed for cutting, grinding and surface preparation on metal, masonry and similar materials. Supplied as a kit with two 3.5Ah batteries, it offers the mobility of cordless operation combined with the power expected from an 18V XR class tool. The compact form factor and 125 mm wheel size make it suitable for working in confined spaces and for tasks that require precise handling.

Advantages

This cordless angle grinder provides cordless convenience and sustained runtime with two 3.5Ah batteries included. Its compact design improves manoeuvrability and user control during cutting and grinding tasks. The 125 mm wheel diameter balances cutting depth and tool size, while the 18V XR platform ensures compatibility with other batteries in the same range. The kit format reduces the need to source batteries separately and allows immediate use on site.

Suitable for

• Cutting metal pipes, rebar and sheet metal with a 125 mm wheel.
• Grinding welds, removing rust and surface material on metal.
• Light masonry cutting and surface preparation on concrete and brick.
• On-site maintenance and repair tasks where access to mains power is limited.
• DIY and professional jobs requiring a compact, portable grinder.

When it may not be suitable

This compact 125 mm angle grinder is not intended for heavy industrial cutting or prolonged high-load grinding where larger machines and corded power are preferred. For tasks requiring deeper cuts, very high removal rates or continuous operation for extended shifts, a larger diameter grinder or a corded model may be more appropriate.

Key specifications

• Wheel diameter: 125 mm
• Battery system: 18V XR compatibility
• Batteries included: two 3.5 Ah lithium-ion batteries
• Tool type: cordless angle grinder (compact design)
• Typical applications: cutting, grinding, surface preparation on metal and masonry

How to use

Fit a suitable 125 mm disc for the intended task, ensuring the chosen disc is rated for the grinder’s operating speed. Insert a fully charged 18V battery into the tool and secure the battery. Use the side handle for stable control and keep the workpiece secured. Start the grinder and allow it to reach full speed before engaging the material. Apply steady, controlled pressure—avoid forcing the tool. After use, allow the disc to slow and stop completely before setting the tool down, then remove the battery prior to changing discs or performing maintenance.

What to consider before purchase

• Confirm that 125 mm discs meet the cut depth and material removal needs of your tasks.
• Ensure compatibility with other 18V XR batteries and chargers you may already own.
• Consider if compact size and portability are priorities versus the need for higher continuous power.
• Check available disc types (cutting, grinding, flap, diamond) suitable for metal or masonry work.

Usage recommendations

For longevity and safe operation, use discs rated for the grinder’s speed, wear appropriate personal protective equipment including eye, ear and respiratory protection, and follow manufacturer maintenance instructions. Rotate between the two supplied batteries to balance runtime and charging cycles during prolonged jobs.
