Sandvik Coromant 6255454 Hydraulic Tool Chuck C6

Product Description

The SANDVIK COROMANT 6255454 is a hydraulic tool chuck designed for precision CNC machining applications. It features a C6 modular connection shank and accepts tools with a 25 mm hole diameter (0.9843 inches). The chuck delivers a 87 mm projection and a 57 mm nose diameter, making it well-suited for operations that require consistent radial accuracy and strong clamping force. With a maximum balanced speed rating of 20,000 RPM and integrated through-coolant capability, this chuck supports high-speed finishing and semi-finishing operations where thermal management and surface quality are critical. Installation is performed by qualified CNC machine tool technicians.

This hydraulic chuck is intended for use in CNC turning centers and machining centers equipped with C6 modular tooling interfaces. The C6 connection is part of the Coromant Capto modular system, and this chuck is configured for applications where extended reach and secure hydraulic clamping are required. It is appropriate for both production shop environments and job shops running high-RPM operations on steel, aluminum, and similar materials. The 36 mm clamping depth provides stable tool grip during aggressive material removal cycles.

Installation Notes

This chuck is installed and serviced by qualified CNC machine tool technicians. Before mounting or removing the chuck, ensure the machine spindle is fully stopped and all axes are at a safe reference position. Follow the machine tool builder and tooling manufacturer torque and clamping procedures as documented in the applicable product manual. Verify through-coolant ports are clear and sealed correctly before returning the spindle to service.
