Dental Contra-Angle Handpiece AC15L | 1:5 Speed Increasing Handpiece

Product Overview

Dental Contra-Angle Handpiece AC15L is a high-speed contra-angle attachment engineered for dental electric motor systems, widely used in restorative treatment, crown preparation, endodontics, prosthodontics and cosmetic dentistry.

With a 1:5 speed increasing transmission ratio, it amplifies motor rotation speed efficiently to deliver powerful, stable cutting performance. Precision internal gear structure adopts high-toughness wear-resistant materials, ensuring smooth rotation, low vibration and minimal noise during long-hour clinical operations.

The slim, lightweight handpiece body provides excellent intraoral accessibility, making it easy to reach posterior molars and tight operating areas, greatly improving operational flexibility and patient comfort. Integrated internal water spray cooling system delivers consistent irrigation to reduce frictional heat, protect dental hard tissues and avoid thermal damage.

Standard connector fits most common dental electric motors on the market. All detachable external components are autoclavable under high temperature and pressure, fully meeting international dental infection control standards. Strict factory calibration guarantees outstanding concentricity and long service life.

Suitable for use with diamond burs and carbide burs, this handpiece is a must-have instrument for general dental clinics, specialist practices and dental labs pursuing efficient digital and traditional restorative workflows.
