Ultra-mini handpiece HP1KL/HP1NL/HP1SL

dentalair-drivendirect

Product overview

• High-speed air turbine handpiece designed for dental applications.
• Key features: Quick Coupling, Fiber Optic illumination, High power output, Zero-Suction aerodynamic design, Dynamic balanced rotor with Rapid Stop Mechanism, optimized ceramic ball bearings and 3-Point Spring Chucking.
• Available head variants: Ultra-Mini Head, and multiple coupling options (KaVo®, NSK® PTL, Sirona® and generator/LED coupling codes).

Main features

• Rapid Stop Mechanism: Flexible seal integrated in the bearing opens under air pressure during operation and closes when air is off to enable fast bur stop (OptiAir benchmark: < 1.66 s). Performance maintained after ≥250 reprocessing cycles.
• 100% Zero-Suction: Aerodynamic design prevents blood, saliva or other bio-material from being drawn back into the handpiece, reducing cross-contamination and extending cartridge life.
• Optimized Ceramic Ball Bearing: Ensures smoother, quieter operation with consistent torque and improved efficiency.
• 3-Point Spring Chucking: Dynamic chucking increases retention force with speed, reaching up to ~40 N for enhanced stability and precision at high rpm.
• Precise Concentricity / Low Run-out: Improved chuck shafts limit run-out to ≤ 4 μm to enhance cartridge stability and cutting precision.
• High-transmittance optical rod / Fiber Optic: High-transmittance fibre optic rod for maximum illumination and temperature resistance during procedures.
• Quick Swap Coupling: Tool-free quick connection for handpiece replacement without unscrewing threads to save time and improve workflow.
