Emuge 6494.401406 Milling Chuck CAT40 Internal Coolant

Product Description

The EMUGE 6494.401406 is a milling chuck designed for use on CAT40 taper spindles in CNC machining centers. It provides a rigid, high-torque connection between the machine spindle and cutting tool, reducing vibration and maintaining concentricity during milling operations. The chuck features internal coolant-through capability, directing coolant fluid directly to the cutting zone for improved chip evacuation and tool life. At 2.442 pounds, it is built for the demands of production machining environments. Installation and tool changes are performed by qualified CNC machinists or toolroom technicians.

This milling chuck is suited for vertical and horizontal CNC machining centers equipped with a CAT40 spindle interface. The internal coolant-through design makes it well matched for deep-pocket milling, high-feed roughing, and applications where flood coolant alone cannot adequately reach the cutting edge. It is appropriate for both job shop and production floor use where consistent tool holding performance is required.

Key Features

• CAT40 taper shank for direct spindle mounting on compatible machining centers
• Internal coolant-through design delivers coolant directly to the cutting tool
• Rigid chuck body supports high-torque milling applications
• Compact and balanced construction at 2.442 pounds
• Compatible with standard CAT40 tooling protocols and retention knobs

Compatibility

Designed as an OEM-style replacement or direct-fit toolholder for CNC machining centers with a CAT40 taper spindle interface and internal coolant supply capability.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Always power down and lock out the machine spindle before mounting or removing any toolholder. Verify that the spindle taper and chuck taper are clean and free of chips or debris before seating. Confirm that the machine coolant-through system pressure is compatible with the chuck before activating internal coolant flow.
