LK-N1-5L Fiber Optic Contra Angle Handpiece
The LK-N1-5L Fiber Optic Contra Angle Handpiece combines precision low-speed performance with integrated fiber optic lighting — delivering a brighter, clearer view of the working area during clinical procedures. This is particularly valuable in situations where overhead lighting or indirect illumination is insufficient, such as posterior tooth work and endodontic access preparation.
The 5:1 reduction contra angle provides increased torque at reduced speed, making it well-suited for finishing burs, polishing cups, and endodontic files. Its smooth, consistent rotation minimises instrument stress and improves tactile feedback for the clinician.
Compatible with standard dental unit connections, the LK-N1-5L integrates seamlessly into most chairside setups. Durable internal components ensure sustained performance with regular maintenance. The lightweight design reduces wrist fatigue during extended clinical sessions.
