Sandvik Coromant 6408304 Cat to Capto Taper Adapter CAT50

Product Description

The SANDVIK COROMANT 6408304 is a CAT to Capto taper adapter designed to bridge CAT50 outside taper spindles with C6 inside modular connections. It provides a 30mm projection and a 63mm nose diameter, with through-coolant capability to support high-pressure coolant delivery directly to the cutting zone. The overall length is 131.80mm. This adapter is installed by machinists and CNC setup technicians working on high-production machining centers where modular tooling systems are used alongside existing CAT50 spindle interfaces. It weighs 5.76 pounds.

This adapter is suited for use in CNC machining environments where CAT50 spindle machines need to accept Capto modular tooling. Typical applications include turning, milling, and boring operations on horizontal and vertical machining centers running Capto-based tooling assemblies. The through-coolant feature makes it applicable in operations where chip evacuation and tool life are critical concerns, such as deep-cavity milling or drilling in difficult materials. Facilities upgrading tooling systems without replacing spindles will find this adapter a direct interface solution.

Key Features

• CAT50 outside taper connection interfaces with existing CAT50 spindle machines
• C6 inside modular connection accepts Capto C6 tooling assemblies
• 30mm projection positions the modular interface forward of the spindle face
• 63mm nose diameter supports stable tooling engagement
• Through-coolant capability delivers coolant directly to the cutting zone
• Overall length of 131.80mm suits standard machining center clearances

Compatibility

Designed for use with CAT50 spindle interfaces and Capto C6 modular tooling systems. Specific machine model compatibility should be confirmed against spindle interface drawings and Capto C6 tooling requirements prior to installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully powered down and the tool changer disabled before mounting or removing the adapter. Ensure all mating tapers and modular connection faces are clean and free of chips, burrs, or coolant residue before assembly. Through-coolant passages should be verified clear before use to prevent pressure loss or contamination of the cutting zone.
