Sandvik Coromant 6408297 Cat to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408297 is a CAT to Capto taper adapter designed to interface a CAT40 outside taper spindle with a C6 inside modular Capto connection. It bridges machine tool spindles and Capto-compatible tooling assemblies, allowing shops running CAT40 machines to take advantage of the Capto modular tooling system without changing spindle hardware. The adapter features an 85mm projection, a 63mm nose diameter, and includes through-coolant capability for wet machining and high-pressure coolant applications. This component is installed by machinists and toolroom technicians in CNC machining centers as part of a precision tooling setup.

This adapter is suited for use in CNC vertical and horizontal machining centers equipped with CAT40 spindles where a transition to Sandvik Coromant Capto modular tooling is required. The through-coolant feature supports drilling, milling, and turning operations that benefit from directed coolant flow at the cutting zone. The 85mm projection provides clearance for a range of toolholder configurations. Typical installations are found in production machining environments handling steel, aluminum, and other common workpiece materials.

Key Features

• CAT40 outside taper spindle connection for standard CAT40 machining centers
• C6 inside Capto modular connection for compatibility with Sandvik Coromant Capto tooling
• 85mm projection for clearance in modular tooling assemblies
• 63mm nose diameter for secure and stable toolholder seating
• Through-coolant design supports directed high-pressure coolant delivery
• Overall length of 153.40mm provides a defined gauge-line-to-nose dimension

Compatibility

Designed for use with CAT40 spindle machines requiring a transition to Capto C6 modular tooling connections. Specific compatible models or replacement part numbers were not provided in the available product data.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC toolholder assembly procedures. The machine spindle must be powered down and brought to a full stop before mounting or removing any toolholder adapter. Taper surfaces should be cleaned and inspected for damage or contamination before assembly, as debris on the taper interface will affect runout and clamping force. Verify that the drawbar retention system in the spindle is compatible with CAT40 pull-stud specifications before use.
