KM4X Drawbars and Grippers

Developed through an exclusive partnership between OTT-JAKOB and Kennametal, the KM4X clamping system is designed to meet the rigorous demands of machining hard-to-cut materials like titanium alloys. Its robust design ensures maximum stability and optimized distribution of clamping force, enabling machines to utilize their full power potential in challenging turning and milling operations. 

Key Features

• High Pull-In Forces | Provides exceptional clamping force, with KM4X63 achieving 36–58 kN and KM4X100 reaching 90–110 kN, ensuring secure tool retention during heavy-duty operations.
• Optimized Clamping Mechanism | Utilizes four spheres that are radially forced outward during clamping, engaging three contact surfaces for maximum stability and precise force distribution.
• Modular System Compatibility | Part of OTT-JAKOB's modular clamping system, allowing for easy configuration and integration with existing setups.
• Durable Construction | Features DLC-coated gripper segments and clamping cones, offering excellent wear resistance and extended service life.
• Coolant Supply Compatibility | Designed to accommodate central coolant supply systems, facilitating efficient cooling and chip evacuation.
