DONG CHENG DCSM08-100-Z Cordless Angle Grinder 4-Inch 20V BL-Motor (tool only)
DONG CHENG DCSM08-100-Z Cordless Angle Grinder 4-Inch 20V (tool only) is a popular must-have item for modern structural fabricators, roofers, and maintenance technicians. Driven by high-performance Brushless Motor technology combined with a 20V lithium-ion battery, it delivers power comparable to a corded angle grinder. It allows you to work smoothly at heights, in tight spaces, or on off-grid job sites without access to electricity. The tool body is designed to be balanced, slim, and lightweight. The top slide switch is convenient to operate and easily locks on. This model is a "tool only (Z-Type)" unit, offering the best value for professionals who already own batteries in Dong Cheng's 20V platform.

Features
- High-Performance Brushless Motor: Intelligent brushless motor provides stable RPM, high durability, low heat accumulation, and saves up to 30% more battery power compared to conventional motors, with no need for carbon brush replacement throughout its lifespan.
- Advanced Safety Electronic Brake: Equipped with an electric safety brake, the grinding or cutting wheel stops spinning rapidly as soon as the operator releases their hand or turns off the switch, reducing the risk of accidental cuts after use.
- Soft Start Function: The soft start system gradually ramps up speed safely, preventing the tool from jerking or twisting out of hand during startup.
- Detachable Dust-Proof Net: Features a fine steel mesh dust-proof screen at the rear air vents to catch metal shavings, concrete dust, and debris from entering and damaging the internal armature and circuit boards. It can be easily detached for blow cleaning.
- Slim Body with Rubberized Grip: The handle features a slimmer design for a secure, ergonomic grip. Coated with special non-slip rubber, it provides anti-vibration benefits, keeping the grinder steady, comfortable to handle, and safe even with sweaty or oily hands.

Applications
- Cutting steel pipes, rebar, box steel, metal sheets, C-line framing, and stainless steel sheets (when used with thin cutting discs)
- Deburring weld beads, smoothing steel seams, or notching angle irons in metal fabrication work
- Removing rust and old paint from metal surfaces and automotive parts (when used with flap discs or wire cup brushes)
- Highly suitable for metal sheet roofing installations, ceiling work, off-site jobs, and emergency service technicians
