The DeWALT DWE4057-QS angle grinder combines a compact design with a high-speed 800 W motor delivering a maximum no-load speed of 11,800 RPM. With a 125 mm (12.5 cm) grinding disc diameter and an M14 spindle thread, this lightweight tool weighs approximately 1.8 kg and is offered in DeWALT's characteristic black and yellow finish. Its size and power balance make it suitable for a wide range of cutting, grinding and surface-preparation tasks where manoeuvrability and control are required.

Advantages

The grinder’s 800 W motor provides consistent power for cutting, grinding and material removal at high speed while maintaining compact dimensions for access in confined spaces. Its 125 mm disc diameter supports a range of standard abrasive and cutting wheels. At around 1.8 kg, the tool reduces operator fatigue during prolonged use and the M14 spindle thread ensures compatibility with widely available accessories. The ergonomic shape and balanced weight distribution assist steady handling and improved control.

How to use

Fit an appropriate 125 mm disc compatible with an M14 spindle and ensure the disc type matches the material and task. Secure the disc and guard before connecting the tool to power. Hold the grinder with both hands for control, position the disc at the desired angle and apply steady, even pressure—avoid forcing the tool. Allow the motor to reach operating speed before engaging the workpiece and move the tool along the surface with smooth, controlled motions. After use, switch off and wait for the disc to stop completely before setting the tool down and disconnecting from the power source.

Recommendations

Use appropriate personal protective equipment such as safety goggles, gloves, hearing protection and a dust mask. Select discs rated for the grinder's no-load speed. Ensure the work area is clear of flammable materials and secure the workpiece properly. Regularly inspect discs and the guard for damage and replace worn or damaged accessories promptly. For cutting masonry or tiles, use discs designed for that material and follow manufacturer guidance.
