The Dongcheng DSM08‑100 (also marketed in some outlets as DSM06‑100) is a 4‑inch (100 mm) corded angle‑grinder powered by an 800 W copper‑wound motor, designed for efficient cutting, grinding, and surface preparation on metal and masonry materials. In the DSM08‑100 version the no‑load speed reaches up to 13 000 rpm, while the DSM06‑100 variant runs at a slightly throttled 9 000 rpm—both in a lightweight body weighing approximately 1.6 kg (DSM08) to 2.0 kg (DSM06). With a 16 mm arbor and M10 spindle thread, the grinder accepts standard 100 mm discs and features a quick spindle‑lock for one‑wrench accessory changes, along with a rear‑toggle power switch for simple on/off control. Internally, it uses durable gears and overload-resistant design, making it suitable for construction, metal‑work, and general DIY applications where reliability matters. Each unit comes standard with a disc‑wrench, a pair of spare carbon brushes, and is packaged in a branded color box for easy retail or tool‑store shelving.
