Sandvik Coromant 6255452 Hydraulic Tool Chuck C5 25mm

Product Description

The SANDVIK COROMANT 6255452 is a hydraulic tool chuck designed for precision metal cutting and high-speed machining operations. It accepts a 25 mm bore diameter and features a C5 modular connection shank, making it compatible with Coromant Capto-style tooling interfaces commonly found on CNC turning centers and machining centers. With a balanced speed rating of 28,000 RPM and integrated through-coolant capability, this chuck delivers consistent clamping force and thermal management during extended cutting cycles. The 88 mm projection and 41 mm clamping depth support a wide range of tool shank lengths. Total package weight is 4.11 pounds.

This hydraulic chuck is suited for production machining environments where tool runout and vibration control are critical. Typical applications include finish boring, reaming, and high-speed milling where hydraulic expansion clamping provides superior concentricity over mechanical collet systems. The C5 modular interface allows fast, repeatable tool changes on machines equipped with compatible Coromant Capto spindle connections. It is installed and serviced by CNC machinists and tooling specialists in job shop, aerospace, automotive, and general manufacturing settings.

Key Features

• Balanced to 28,000 RPM for high-speed machining stability
• Through-coolant design channels fluid directly to the cutting zone
• 57 mm nose diameter and 88 mm projection support a broad range of tooling setups
• Overall length of 118 mm for consistent gage-line referencing

Compatibility

Designed for use with C5 modular connection Coromant Capto-style machine spindles. Accepts tool shanks with a 25 mm diameter. Through-coolant compatible with machines equipped with internal coolant delivery systems.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Confirm the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the chuck. Follow the machine tool builder guidelines for torque and seating of modular connection shanks. Verify through-coolant port alignment and check for leaks before resuming cutting operations.
