CoroMill® 345

Low cost per component

​Double-sided inserts with eight cutting edges for optimal performance when it comes to material removal and surface finish, paving the way for truly cost-efficient machining.

Secure machining

Extremely robust cutter body and shim-protected tip seats give security to the machining process, making the cutter body a good choice if unmanned production is a priority.

Internal coolant

​Internal coolant supply to each insert pocket ensures effective chip evacuation and good performance also in demanding materials.

Positive cutting action

The positive axial inclination at small depths of cut offers a soft cutting action with low axial pressure on the workpiece. As the depth of cut increases, a more upright part of the cutting edge is engaged, providing a more substantial structure for high security, especially in tougher cuts.
