Sandvik Coromant 6408300 CAT50 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408300 is a CAT50 outside taper to Capto modular taper adapter designed for use in CNC machining centers and turning centers that require conversion between CAT-style spindle interfaces and Capto modular tooling connections. This adapter features a C4 inside modular connection, a 30mm projection length, and a 40mm nose diameter. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone. It is installed by toolroom technicians and setup machinists working with mixed-interface tooling configurations. At 3.8 pounds, the adapter is machined to close tolerances appropriate for precision metal cutting applications.

This adapter is suited for shops running CAT50-spindle machining centers that need to interface with Capto C4 modular tooling systems. Typical applications include production machining environments where multiple tooling platforms must share spindle inventory, or where Capto quick-change tooling is being integrated into an existing CAT50 machine park. The through-coolant design supports both flood and high-pressure coolant strategies during milling, drilling, and boring operations.

Key Features

• CAT50 outside taper interfaces directly with CAT50-spindle machining centers
• C4 inside Capto modular connection for compatibility with Capto tooling assemblies
• 30mm projection length for defined gage-line positioning
• 40mm nose diameter provides rigid support for modular tooling units
• Through-coolant construction enables high-pressure coolant delivery to the cutting zone
• Overall length of 131.8mm supports predictable tool assembly stack-up calculations

Compatibility

Designed for use with CAT50-spindle machine tools requiring a Capto C4 modular inside connection interface. Specific machine and tooling compatibility should be confirmed against the Capto C4 modular tooling system specifications.

Installation Notes

Installation should be performed by a qualified toolroom technician or setup machinist familiar with CNC tooling assembly procedures. The machine spindle must be fully powered down and locked out before handling or installing taper adapters. Mating tapers and clamping bores should be cleaned and inspected for burrs or contamination prior to assembly to ensure proper seating and runout performance. Torque and clamping requirements should be referenced from the machine tool and tooling system manufacturer documentation.
