Jinme J7 Quick NSK Style Coupling Handpiece

The Jinme J7 Quick NSK-Style Coupling Handpiece is a high-speed turbine handpiece designed with a 4-hole quick-coupling connection compatible with NSK-style couplers. It operates at 350,000–380,000 RPM under 0.23–0.25 MPa working air pressure, with water flow of 90–110 mL/min for cooling and noise held to 60dB or below. The body carries a titanium coating for durability, and rotation runs on German ceramic bearings for smooth, quiet performance. Bur changes use a push-button mechanism for quick, one-handed swaps between procedures. The handpiece is autoclave sterilizable at up to 135°C and is backed by an 18-month manufacturer warranty. Because it uses a quick-coupling design rather than a fixed hose connection, confirm coupler compatibility with your existing tubing/motor setup before ordering, and follow the manufacturer's sterilization and maintenance schedule to help preserve bearing life and cutting performance over repeated use.
