Sandvik Coromant 6255483 Hydraulic Tool Chuck C6 12mm

Product Description

The SANDVIK COROMANT 6255483 is a hydraulic tool chuck designed for precision metal-cutting and machining operations. It uses a C6 modular connection shank to interface with compatible tooling systems and accepts shanks with a 12 mm hole diameter. The chuck delivers a 107 mm projection length and a 51 mm clamping depth, providing secure tool retention with minimal runout. Rated to 20,000 RPM, it is suited for high-speed milling, drilling, and reaming applications. Through-coolant capability directs cutting fluid directly to the cutting zone, supporting tool life and chip evacuation. This chuck is installed by machining center operators and CNC setup technicians.

This hydraulic chuck is intended for use in CNC machining centers, milling machines, and similar machine tool spindles that accept C6 modular connection tooling. The 22 mm nose diameter and 107 mm projection make it appropriate for applications requiring extended reach with a compact nose profile. Through-coolant support is particularly useful in deep-hole drilling and high-speed finishing passes where consistent coolant delivery is critical. It is suited to both production and job-shop environments where repeatable tool clamping is required.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling setup technician. Power down and lock out the machine spindle before mounting or removing the chuck. Follow the machine tool manufacturer torque and mounting procedures for C6 modular connections. Verify runout and balance condition at the intended operating RPM before returning the spindle to production use.
