Product overview This professional rotary tattoo pen uses magnetic rotary drive technology with a brushless motor and magnetic bearing to deliver stable, precision needle movement. Designed for consistent contact and low vibration, the unit is suitable for detailed lining, shading, and color work. Key benefits precision: needle contact accuracy up to 0.01 mm for consistent strokes and reliable repeatability. Low vibration: vibration value below 2.5 um for smoother handling and reduced hand fatigue. Adjustable needle stroke: supports adaptive needle distance adjustment from 2.8 mm to 4.0 mm to match different needle types and techniques. Stable speed control: host adjustable from 30 to 150 Hz to fine tune speed for lining or shading. Ergonomic, durable design: lightweight pen at 85 g with a 28 degree angled grip for natural hand placement; aviation titanium alloy shell with antiskid nano coating for a secure feel.
