Highlights

All the new inserts are available in IC20N and IC520N cermet grades to be used mainly for machining steel.

The cermet grades, when compared to regular cemented carbide, are characterized by a greater hardness that enables machining at higher cutting speeds, improved wear resistance and the ability to prevent built-up edge.

Cermet grade location relative to other materials:


The main advantages of cermet grades are for applications that require high surface quality, dimensional stability and tight tolerances.
Cermet grades usually guarantee longer tool life at small to medium chip load and uniform workpiece dimensions. They are ideal for fine and semi-finishing of steel, sintered metal, ductile cast iron and stainless steel.

ISCAR offers a wide range of chipformers and geometries for indexable negative and positive inserts including wiper corner configurations.
These chipformers were designed to ensure reliable chipbreaking in automated machining applications.

These cermet families include chipformers for a specific geometry which should help in selecting the most suitable chipformer according to the specified application range for each chipformer type.

Attached are sketches that describe the application range for each chipformer.
