Sandvik Coromant 6408299 CAT50 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408299 is a CAT50 outside taper adapter designed to connect CAT50 spindle interfaces to Capto modular tooling systems. It features a C3 inside modular connection, a projection of 60 millimeters, and a nose diameter of 32 millimeters. Through-coolant capability allows cutting fluid to pass directly through the adapter to the cutting tool, supporting high-performance machining applications. This adapter is installed by machinists and CNC tooling technicians working on machining centers equipped with CAT50 spindles that require Capto-style tool assemblies.

This adapter fits machining centers with CAT50 spindle tapers and bridges the interface to Capto modular tooling. It is suited for shops running mixed tooling systems where Capto cutting units need to be mounted on CAT50-equipped machines. The through-coolant design makes it appropriate for applications involving deep-hole drilling, high-speed milling, or other operations where directed coolant delivery is critical to tool life and chip evacuation. Total overall length is 161.8 millimeters.

Key Features

• CAT50 outside taper interface for direct spindle mounting on CAT50 machining centers
• C3 inside Capto modular connection for compatibility with Capto tooling assemblies
• 60 millimeter projection length for tool positioning flexibility
• 32 millimeter nose diameter supports a range of Capto cutting unit sizes
• Through-coolant design delivers cutting fluid directly to the tool tip
• Overall length of 161.8 millimeters for predictable gage-line calculations

Compatibility

Designed as an OEM-style adapter for CAT50 spindle machining centers requiring a Capto modular tooling interface at the C3 connection size.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. The spindle must be fully powered down and the machine placed in a safe, locked-out state before handling any spindle tooling. Verify that the CAT50 taper and the C3 Capto connection are clean and free of chips or debris before assembly. Follow the machine tool builder and tooling manufacturer torque and retention specifications provided in the machine documentation.
