The DEWALT DWE4157 900 W 125 mm Angle Grinder is a corded model for cutting, grinding, and surface-finishing work, particularly on metal. It accepts 125 mm discs. The 900 W motor reaches a maximum no-load speed of 11,800 RPM, suitable for routine stock removal and abrasive cutting in workshop, construction, and maintenance settings. Mains AC power allows continuous operation during extended jobs.
The grinder weighs 2.05 kg, which matters during prolonged or overhead use. Its low-profile gearbox housing improves access in confined spaces. The slim body and soft-grip handle give better control on longer jobs. Soft start reduces initial movement when the motor starts, and restart protection prevents unintended operation after a power interruption. The auxiliary side handle provides a second holding point for steadier two-handed control.
