Sandvik Coromant 5730127 ER32 Collet Chuck C6 Modular

Product Description

The SANDVIK COROMANT 5730127 is an ER32 collet chuck with a modular connection shank designed for precision CNC machining applications. It accepts the ER32 collet series and features a C6 modular connection interface, making it compatible with modular tooling systems that use that shank size. The chuck offers a 2.3622-inch projection and a 3.8583-inch overall length, with a 1.9685-inch nose diameter. Through-coolant capability directs cutting fluid directly to the cutting zone for improved chip evacuation and tool life. Actuation is by wrench. The unit is balanced to 20,000 RPM, supporting high-speed spindle applications. Machinists and CNC toolroom technicians install this chuck as part of a modular tooling assembly.

This collet chuck is suited for use in machining centers and CNC milling or turning applications where modular tooling systems with C6 connections are in use. The ER32 collet system accommodates a wide range of shank diameters, making it a versatile holding solution for end mills, drills, reamers, and similar rotary cutting tools. Through-coolant support makes it appropriate for deep-hole drilling, high-feed milling, and other operations where flood coolant alone is insufficient. The chuck is intended for professional machine shop environments where precise tool projection and runout control are required.

Key Features

• ER32 collet system accepts a broad range of cutting tool shank diameters
• C6 modular connection shank for use with compatible modular tooling interfaces
• 2.3622-inch projection provides defined reach from the spindle face
• Balanced to 20,000 RPM for high-speed machining compatibility
• Through-coolant design delivers coolant directly to the cutting zone
• Wrench actuation for reliable collet clamping and release

Compatibility

Designed for modular tooling systems that use a C6 modular connection interface and accept ER32 series collets. Specific machine and toolholder system compatibility should be verified against the spindle and modular coupling specifications of the target machine tool.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. The machine spindle must be fully stopped and the machine placed in a safe, locked-out state before mounting or removing the chuck. Use the appropriate ER32 collet nut wrench and spanner to achieve proper clamping torque - consult the machine tool manufacturer and tooling system documentation for correct procedure. Verify that the through-coolant port is properly seated and sealed within the modular connection before resuming operation.
