Sandvik Coromant 6408296 CAT40 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408296 is a CAT-to-Capto taper adapter designed to bridge a CAT40 outside taper spindle with a C5 Capto inside modular connection. It allows machinists and tooling technicians to run Capto-style modular tooling on CAT40 spindle machines without replacing the machine spindle or tool holder inventory. The adapter features through-coolant capability, delivering coolant directly to the cutting zone for improved chip evacuation and tool life. With an 80mm projection and a 50mm nose diameter, it is suited for applications where reach and rigidity are both required. This adapter is installed by tooling setup technicians and CNC machinists in production machining environments.

This adapter is used in CNC machining centers equipped with CAT40 spindle interfaces where operators need to use Capto modular tooling systems. It is appropriate for both roughing and finishing operations where through-coolant delivery is beneficial, such as deep-pocket milling, boring, and turning center live tooling setups. The C5 Capto inside connection is compatible with the Sandvik Coromant Capto modular tooling system at the C5 size designation. No specific machine model compatibility is stated in the available product data.

Key Features

• CAT40 outside taper interfaces directly with standard CAT40 machine spindles
• C5 Capto inside modular connection accepts C5-size Capto tooling heads
• Through-coolant design delivers coolant to the cutting zone for improved performance
• 80mm projection provides extended reach for deep-feature applications
• 50mm nose diameter supports rigid clamping of modular Capto units

Compatibility

Designed for use with CAT40 spindle machines and compatible with the Capto C5 modular tooling interface. No additional specific machine model or system family compatibility data was provided in the available product information.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Power down and lock out the machine spindle before mounting or removing the adapter. Ensure mating tapers are clean and free of chips, burrs, or contaminants before assembly, as surface contamination on precision tapers directly affects runout and clamping force. Torque the retention knob to the machine spindle manufacturer specification using the appropriate pull-stud and drawbar configuration for CAT40 tooling.
