Koriko Carbide Inserts & High-Performance Indexable Tooling

Koriko is a globally acknowledged leader in the design and manufacture of high-efficiency indexable carbide inserts, turning tools, and milling systems. Engineered specifically for demanding material removal applications, Koriko inserts leverage state-of-the-art multi-layer CVD (Chemical Vapor Deposition) and PVD (Physical Vapor Deposition) coating technologies. These advanced surface treatments provide extreme resistance to crater wear, thermal cracking, and built-up edge (BUE), making them the preferred choice for industrial machine shops, aerospace fabricators, and automotive components manufacturers across India.

Premium Coating Technologies & Insert Grades

The core advantage of Koriko tooling lies in its proprietary substrate metallurgy and advanced coating layers. Koriko's CVD coated grades are optimized for high-speed continuous turning of cast iron and medium-to-carbon steels. The thick Aluminum Oxide (Al2O3) and Titanium Carbonitride (TiCN) coatings provide a powerful thermal barrier, allowing CNC operators to run at elevated cutting speeds (Vc) without compromising tool life.

For interrupted cuts and stainless steel machining, Koriko's PVD coated inserts feature ultra-fine grain structures combined with Titanium Aluminum Nitride (TiAlN) coatings. This offers unmatched toughness and prevents micro-chipping along the cutting edge. Additionally, the optimized chipbreaker designs ensure excellent chip control, reducing power consumption on the CNC spindle and improving surface finish roughness (Ra) values.

Frequently Asked Questions

What materials are Koriko inserts suitable for?

Koriko inserts are engineered to machine a wide range of materials, including carbon steels, alloy steels, stainless steel, cast iron, and high-temperature superalloys. Selecting the right grade and chipbreaker is key to optimal performance.

How do I choose between CVD and PVD coated inserts?

Use CVD-coated grades for high-speed, continuous turning operations where thermal resistance is crucial. Choose PVD-coated grades for interrupted cuts, milling operations, stainless steel, and aerospace alloys requiring high edge toughness.
