Integrated Low-Speed Handpiece System with Internal Water Channel

The Internal Series Low-Speed Handpiece system offers a complete and efficient solution for a wide range of dental procedures. With four essential components and a built-in water channel system, this setup is engineered to deliver consistent cooling, ergonomic comfort, and clinical precision.

Comprehensive 4-Piece System

  • Motor Unit (120090): The foundation of the system, offering reliable low-speed motor performance.

  • Standard Contra-Angle (120094): A press-type design suitable for general dental applications.

  • LED Fiber Optic Contra-Angle (120091): Provides enhanced visibility through integrated illumination.

  • Straight Handpiece (120097): Ideal for anterior regions and accessible areas requiring direct access.

Internal Cooling Technology

This system features an internal water channel that delivers reliable and precise cooling during operation. The design minimizes external tubing, resulting in a more streamlined, ergonomic tool that ensures effective temperature regulation across longer procedures.

Enhanced Visibility with LED Illumination

The optional LED fiber optic contra-angle offers targeted lighting directly at the treatment site, improving clinical accuracy while reducing eye strain for the practitioner. This added visibility is especially beneficial during intricate and low-light procedures.

User-Centric Engineering

The system supports tool-free disassembly, enabling fast and thorough cleaning without requiring specialized training. Each component is modular, promoting quick maintenance and reassembly, thus reducing downtime and extending the handpiece’s service life.

Sterilization-Ready Design

Engineered for compatibility with high-temperature and high-pressure autoclave sterilization, the handpiece components maintain integrity and performance through repeated cycles, ensuring long-term durability and hygiene compliance.

Durable Build and Functional Features

Crafted with a stainless steel press-type rear cover, the system offers long-lasting durability and corrosion resistance. The intuitive bur locking mechanism provides secure engagement and easy exchange, enhancing both safety and workflow efficiency.

Universal E-Type Compatibility

All handpieces within the system use the standard E-type interface, ensuring wide compatibility with most dental units and motors. This facilitates quick interchangeability for various clinical needs, maximizing versatility without compromising performance.

Simplified Maintenance Protocols

The accessible design enables comprehensive internal cleaning, reducing chair-side maintenance time. Proper care supports optimal performance and extends the operational life of each handpiece in the system.
