Sandvik Coromant 5730055 ER40 Collet Chuck C6 Modular

Product Description

The SANDVIK COROMANT 5730055 is an ER40 collet chuck with a modular connection shank designed for precision CNC machining applications. It accepts the ER40 collet series and features through-coolant capability to direct fluid directly to the cutting zone, improving chip evacuation and tool life. The chuck projects 2.5591 inches from the modular connection interface, with an overall length of 4.0551 inches and a nose diameter of 2.4803 inches. The C6 modular connection size ensures rigid, repeatable coupling to compatible tooling systems. Actuation is performed with a standard wrench. The assembly is balanced to 20,000 RPM, making it suitable for high-speed machining operations where vibration control is critical.

This collet chuck is used in CNC machining centers running high-speed milling, drilling, or reaming operations that require consistent tool runout and active coolant delivery. The ER40 collet range accommodates a wide span of tool shank diameters, making this chuck a versatile station in both production and job-shop environments. The C6 modular connection is a common interface on machines and toolholding systems that support Sandvik Coromant modular tooling platforms. Installation is typically performed by a machinist or toolroom technician setting up a live-tool or spindle station.

Key Features

• ER40 collet system for broad tool shank diameter range
• C6 modular connection shank for rigid, repeatable coupling
• Through-coolant capability for direct cutting-zone fluid delivery
• Balanced to 20,000 RPM for high-speed machining stability
• 2.5591-inch projection with 4.0551-inch overall length

Compatibility

Designed for use with ER40 collets and compatible with tooling systems that accept a C6 modular connection interface.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and machine power isolated per shop lockout/tagout procedures. Use the correct ER40 collet nut wrench and collet clamping torque procedures per the machine tool manufacturer guidelines. Verify through-coolant passage alignment and sealing before returning the assembly to service. Inspect the modular connection interface for debris or damage before mounting.
