The DONGCHENG 580 W Corded Electric Powerful Jigsaw (model DMQ85 / DMQ85S) is a robust plunge-cut jigsaw designed for medium-duty industrial, automotive, and DIY use. Powered by a 580 W motor, it delivers adjustable blade speeds from 500 to 3,100 strokes per minute (rpm) for precise control across materials. It cuts cleanly up to 85 mm in wood, 10 mm in mild steel, and handles plastics, rubber, and cement board, with bevel cut angles adjustable between 0° and 45° on both sides. Built with a die‑cast aluminum alloy gearbox, the jigsaw ensures durability and smooth gear action, supported by six-step electronic speed control and a three‑setting orbital (pendulum) stroke design for fine or aggressive cutting applications with minimal tear‑out. At 2.7 kg net weight, its ergonomic top‑handle grip and compact profile relieve user fatigue during extended sessions. The tool comes with essential accessories including three HSS blades (T144D, T118A, T111C), carbon brush, blade gauge, hex wrench, plastic base, and a color box, making it ready for immediate operation. A 6‑month manufacturer’s warranty applies.
