DongCheng 4-1/2 in Angle Grinder, 6.7-Amp, 11,800 RPM – Dual Guard + Accessories

Power and precision for metalworking

Meet the DongCheng DSM14-115 angle grinder, a compact 4-1/2-inch tool built to tackle metal cutting, rust removal, and surface finishing. Harnessing a 6.7-Amp (800W) copper motor, it reaches up to 11,800 RPM, delivering fast material removal and smooth starts across a range of projects.

Safety and control are built into every detail. The no-lock-on paddle switch stops instantly when released, helping prevent accidental activation. A pair of interchangeable guards lets you switch between cutting and grinding tasks without changing tools, while the lightweight, balanced feel reduces hand fatigue during longer sessions.

Durability, cooling, and real-world reliability

Designed for demanding use, the tool features precision-forged spiral-bevel gears that boost torque resistance by about 30%, along with a multi-vent cooling system that helps manage heat during extended work. A dust-resistant construction protects critical parts, extending tool life compared with typical models.

Weighing just 4.2 lbs with a comfortable grip and a 9-foot cord, it’s built for mobility on busy job sites. Whether you’re removing rust, smoothing rough edges, or prepping metal for finishing, this grinder is designed to keep pace with your workflow.
