Coromant® EH - Modular system

Tooling flexibility for small diameters

Access with shanks

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

Productivity with integrated machine adapters

The short gauge length of an integrated machine adapter 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 the milling of deep shoulders with stability and clearance.

View More Features

  • Great tooling flexibility – choose from an extensive variety of heads, adapters and shanks
  • Reduced tool inventory with standardized tools, minimizing machine downtime
  • Excellent tool utilization and easy handling thanks to the reliable and accurate coupling of head and shank
  • The high rigidity of the short tool assembly makes it possible to increase cutting depths without losing stability
  • Silent Tools™ adapter with Coromant EH interface for machining with long overhangs

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 adapters. In short overhang applications, it can be possible to increase your productivity with integrated machine adapters.
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 the quick mounting of heads. The coupling has a physical stop that 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.

Steel

Heavy metal

Solid carbide

Small to medium machining centers

The short tool assembly consisting only of the integrated machine adapter and cutter head gives high productivity when the gauge line is critical.

Steep taper

HSK

Medium to large machining centers and multi-task machines

Modularity with Coromant Capto® in different lengths offers accessibility for hard-to-reach features.

Coromant Capto®

Turning centers with driven tool holders

The short tool assembly consisting only of the adapter and head gives high productivity when the gauge line is critical or the swing diameter is limited.
