Dynabrade's Mini-Dynafile II is a lightweight, air-powered abrasive-belt machine for grinding, blending, and deburring in normally inaccessible areas.
Running at 25,000 RPM, the machine uses 0.125- to 0.5-in.-wide by 12-in.-long abrasive belts. The tool accepts coated and abrasive-impregnated nonwoven nylon belts. The multipositioning grinding head pivots 180 degrees.
The lightweight composite housing helps reduce vibration and is thermal-insulated to prevent cold air transmission to the operator’s hands. The air motor is adjustable to ensure comfortable throttle lever position. Eight different contact arms are available.
The tool is suitable for finishing and deburring within narrow openings, blending stainless steel, and grinding right-angle welds.
