The Dentmark Endodontic Contra Angle Head (16:1, CH5) is a precision-engineered reciprocating endodontic attachment compatible with NSK, Dentsply, and Dentmark micromotor systems. Designed for controlled, vertical reciprocating motion during root canal instrumentation, it delivers reliable performance for hand file-based endodontic procedures.

Technical Specifications:

• Model: CH5
• Gear Ratio: 16:1 reduction
• Motion Type: Vertical Reciprocating
• Stroke Length: 0.4mm
• Maximum Speed: 4,000 RPM
• File Compatibility: Hand files Ø2.35mm
• Chuck Type: Push-Button Chuck
• Motor Compatibility: NSK, Dentsply, and Dentmark micromotor systems

Key Features:

• 16:1 Gear Reduction – precise torque control for safe endodontic instrumentation
• Vertical Reciprocating Motion – 0.4mm stroke for effective canal negotiation and filing
• Push-Button Chuck – quick, secure file changes without additional tools
