Sandvik Coromant 5721509 Milling Shank Coromant Eh

Product Description

The SANDVIK COROMANT 5721509 is a replaceable tip milling shank in the Coromant EH series, designed for use with interchangeable cutting tip systems on CNC machining centers and milling operations. The shank features a straight round shank with an E12 neck thread connection for secure tip engagement and repeatable seating. With a 0.25 inch projection and a 3 inch overall length, this steel shank is built for precision tool assembly in production environments. It is installed by machinists and tooling technicians as part of a modular tooling setup, offering flexibility when switching cutting geometries without replacing the full holder body.

This shank is suited for milling applications in both light and heavy production environments where modular tooling systems provide changeover efficiency. The Coromant EH interface is a recognized standard for replaceable tip connections, making this shank a component in AExx-Axx-SS toolholder configurations. It is commonly used in vertical and horizontal machining centers where straight shank holders are required. No coolant-through capability is present, making it appropriate for external coolant applications or dry machining setups where internal coolant delivery is not required.

Key Features

• Coromant EH series interface with E12 neck thread connection for repeatable tip engagement
• 0.25 inch projection with 3 inch overall length for compact reach in modular assemblies
• Straight round shank in AExx-Axx-SS toolholder style for standard machine spindle compatibility
• 0.4803 inch neck and nose diameter for consistent radial positioning
• Steel construction for rigidity and durability under milling loads
• No Weldon flat — full round shank retention relies on collet or chuck clamping

Compatibility

Designed for use in AExx-Axx-SS toolholder configurations within the Coromant EH modular milling system, accepting replaceable tips with an E12 thread connection. Specific compatible tip part numbers were not included in the product data and should be confirmed against the Coromant EH system documentation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular milling systems. Ensure the machine spindle is fully stopped and the tool is secured in the toolholder before engaging the replaceable tip. The E12 thread interface should be inspected for debris or damage prior to assembly, and the tip should be tightened with the appropriate torque wrench per the system interface specifications provided by the manufacturer. Do not use the shank if the neck thread shows signs of wear or deformation.
