Sandvik Coromant 6408186 Milling Shank Coromant Eh

Product Description

The SANDVIK COROMANT 6408186 is a replaceable tip milling shank designed for modular tooling systems in precision machining applications. Built to the Coromant EH interface standard, it features a straight round shank with a shank diameter of 0.4606 inches (11.70 mm) and an overall length of 4.3307 inches (110 mm). The neck diameter measures 0.4567 inches and accepts an E12 thread connection to the replaceable cutting tip. Constructed from steel, this shank is suited for CNC milling setups where tip changeability reduces downtime and tooling costs in production environments.

This shank is intended for use in CNC machining centers and milling operations where the Coromant EH modular system is employed. The EHxx-Axx.x-SH toolholder style makes it compatible with corresponding EH-series replaceable milling heads. It is typically installed by machinists and CNC tooling specialists in both job shop and high-volume production settings. No coolant-through capability is present in this configuration, and no Weldon flat is included on the shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the shank. Thread engagement between the shank and replaceable tip should be checked for proper seating and torque per the toolholder manufacturer guidelines. Inspect the E12 thread interface for debris or damage before assembly to maintain runout accuracy.
