Sandvik Coromant 5730118 ER25 Collet Chuck C6 Modular

Product Description

The SANDVIK COROMANT 5730118 is an ER25 collet chuck with a modular connection shank designed for precision CNC machining applications. It accepts the ER25 collet series and connects via a C6 modular interface, providing a rigid and repeatable tooling setup. The chuck features a 3.937-inch projection and an overall length of 5.433 inches, with through-coolant capability to direct fluid directly to the cutting zone. Balanced to 20,000 RPM, it is suited for high-speed machining operations where runout and vibration control are critical. Actuation is by wrench. Licensed machinists and CNC setup technicians are the primary installers.

This collet chuck is intended for use in machining centers equipped with a C6 modular tooling interface. The ER25 collet system accommodates a wide range of tool shank diameters, making this chuck a versatile choice for milling, drilling, and reaming operations in both production and job-shop environments. The through-coolant feature supports high-speed and deep-hole work where flood coolant alone is insufficient to maintain tool life and chip evacuation.

Key Features

• ER25 collet system for broad tool shank diameter range
• C6 modular connection shank for repeatable, rigid setup
• 3.937-inch projection for extended reach applications
• Balanced to 20,000 RPM for high-speed machining compatibility
• Through-coolant capability for improved chip evacuation and tool life
• Wrench actuation for straightforward collet clamping

Compatibility

Designed for use with C6 modular tooling interfaces and ER25 series collets. Verify machine spindle interface and collet size before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician familiar with modular tooling systems. Power down and lock out the machining center spindle before changing tooling. Ensure the modular connection mating surfaces are clean and free of chips or burrs before assembly. Confirm collet seating and torque the collet nut to the tool manufacturer-specified value using a calibrated ER collet wrench.
