Jinme 1:5 Electric handpiece

The Jinme 1:5 Electric Handpiece is a speed-increasing contra-angle attachment designed to pair with an electric micromotor for high-speed cutting and finishing work. It delivers up to 200,000 RPM with a maximum torque rating of 5 N·cm, running on 6 German-made bearings housed in a compact 12.7 mm-diameter body, notably slimmer than the 13.6 mm typical of comparable attachments for better visibility and access. Triple water spray provides consistent cooling to protect both tooth structure and the handpiece from heat buildup, with temperature rise measured at no more than 8.5°C over 5 minutes of continuous use. Fiber optic illumination outputs 12,500 lux for a clearly lit working field. An anti-suck (anti-retraction) structure is built in to help prevent backflow of oral fluids into the handpiece, reducing cross-contamination risk between patients.
