Coromant EH

Access with shanks

Shanks in different lengths and materials enable you to bore hard-to-access features with ease.

Productivity with integrated machine adaptors

​​The short gauge length of an integrated machine adaptor plus cutter head makes it possible to increase productivity even in small, vibration-sensitive machines.​

Clearance and reach

​​The flexible range of undersized shanks in various lengths enables milling of deep shoulders with stability and clearance.​

Modular system for small diameters

The modular system Coromant EH enables you to get the most out of your cutting edge. Get the required reach and accessibility with shanks and modular adaptors. In short overhang applications, it can be possible to increase your productivity with integrated machine adaptors.

The modularity eliminates the need for a separate tool for each machine, component and feature. Combine different tool holders and cutter heads to get an optimized tooling solution for all your machining.

The Coromant EH coupling is based on a centering screw that facilitates quick mounting of heads. The coupling has a physical stop which makes it easy to feel when the head is correctly tightened and helps to not overstress the clamping.​

Application and tool variants

Large machining centres

Use undersized shanks for stability and clearance when machining with long overhang.
