Sandvik Coromant 5730082 ER25 Collet Chuck C5 Shank

Product Description

The SANDVIK COROMANT 5730082 is an ER25 collet chuck with a modular connection shank designed for precision CNC machining applications. It accepts ER25 series collets and features a C5 modular connection interface, making it compatible with Coromant Capto and similar modular tooling systems. The chuck offers a projection of 2.1654 inches from the gage line, an overall length of 3.3465 inches, and a nose diameter of 1.6535 inches. Through-coolant capability directs cutting fluid directly to the cutting zone, supporting higher material removal rates and extended tool life. The chuck is balanced to 28,000 RPM, making it suitable for high-speed machining centers. Actuation is by wrench. This is a single-piece item weighing 1.39 pounds.

This collet chuck is used in CNC machining centers and turning centers equipped with modular tooling interfaces. The C5 modular connection shank is a common interface on mid-size machining platforms used in aerospace, automotive, and general metalworking production environments. It is typically installed by CNC machinists or tooling setup technicians as part of a modular tooling assembly. The ER25 collet system accommodates a wide range of shank diameters, making this chuck a versatile choice for drilling, reaming, and light milling operations where runout accuracy and high spindle speeds are required.

Key Features

• ER25 collet system accepts standard ER25 series collets for flexible workholding
• C5 modular connection shank provides repeatable, rigid tool mounting without a full spindle change
• Balanced to 28,000 RPM for use on high-speed machining centers
• Through-coolant capability delivers cutting fluid directly to the tool tip
• Projection of 2.1654 inches allows reach into deeper features without extended holders
• Wrench actuation for positive collet clamping and controlled torque application

Compatibility

Designed for use with C5 modular connection tooling systems and standard ER25 series collets. Consult your machine tool documentation to confirm the modular connection interface specification before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle or modular turret is fully powered down and locked out before mounting or removing the chuck. Clean all mating surfaces on the modular connection interface before assembly to ensure proper seating and runout performance. Verify collet and collet nut condition before use, and apply the recommended wrench torque per the collet manufacturer's specification for the ER25 system.
