DONG CHENG DSJ05-25 Die Grinder 550W
DONG CHENG DSJ05-25 Straight Die Grinder 550W: An industrial-grade power tool specifically designed for metalworkers, machinists, cylinder head modifiers, and metal finishing fabricators. Featuring a slim, elongated cylindrical design with excellent balance, it allows you to access and grind inner bores, narrow pipes, grooves, or deburr in areas that standard 4-inch angle grinders cannot reach. Driven by a genuine 550W copper motor that delivers an exceptionally high and stable speed, it ensures high precision without bit wobble, elevating your workpiece finishing to be smooth, neat, and flawless.

Features
- Powerful 550W Motor: High-performance 550W motor delivers consistent power, maintaining speed even when applying heavy pressure on thick metal surfaces.
- 6 mm Precision Collet: 6 mm collet chuck made from premium-grade hardened steel securely clamps grinding, sanding, and polishing bits, ensuring safety and reducing hand vibration during high-speed operation.
- Variable Speed Control: Equipped with a multi-speed adjustment system (9,000 - 26,000 rpm), allowing users to select the optimal speed for different types of grinding accessories and materials, such as plastics, wood, or hardened steel.
- Slim and Lightweight Body: The ultra-slim body design and total weight of only 1.6 kg allow steady, pen-like control, enabling continuous work without wrist fatigue.
- Excellent Heat Dissipation: Engineered rear and front ventilation vents direct airflow to quickly blow out dust and dissipate accumulated heat from the tool, prolonging the service life of the armature and field coil.

Applications
- Mold and die making, as well as porting/modifying intake and exhaust ports on automotive and motorcycle engine blocks.
- Deburring weld seams, drilled steel holes, sheet metal, or cast iron parts in structural industries.
- Rust removal, grooving, solder cleaning, and surface preparation on metal and wood in narrow, confined spaces.
- D.I.Y. decorating, fretwork/wood carving, or marble engraving requiring high precision
