HC-K210
HC-K210 Micro Die Grinder
The air micro grinder—often called a pencil grinder—is the ultimate precision instrument for high-speed detailing. It bridges the gap between heavy industrial grinding and delicate hand-finishing.
Ultra-High Speed: Operating at speeds often exceeding 56,000 RPM, it utilizes centrifugal force to provide smooth, effortless cutting and polishing.
Pencil-Grip Ergonomics: Designed to be held like a pen, it offers unparalleled control for intricate designs and maneuvering in "hard-to-reach" internal geometries.
Pneumatic Efficiency: Powered by compressed air, the tool remains cool to the touch during continuous use, unlike electric alternatives that may overheat.
Industrial Versatility: A true multi-tasker that adapts to any job—from deburring machined parts and porting engines to engraving fine jewelry.
| Feature | Benefit |
| Slim Profile | Allows access to tight cavities and complex molds. |
| Variable Throttle | Precise control over speed for different materials (metals, plastics, or glass). |
| Rear Exhaust | Directs air away from the workpiece to prevent debris from blowing into the user's face. |
| Interchangeable Collets | Supports a vast array of burrs, stones, and polishing bobs. |
Whether you are in aerospace engineering, mold making, or denture lab work, the air micro grinder is the go-to solution for removing imperfections without damaging the surrounding material. It is the gold standard for any professional requiring surgical-level accuracy on metal surfaces.
Pro Maintenance Tip: To ensure a long lifespan and peak performance, always use a dedicated Air Line Lubricator to provide a constant mist of oil to the high-speed turbine.
