What are Cermet Inserts?

Cermet inserts are advanced cutting tools made from a composite material that combines ceramic (cer) and metal (met). This unique blend provides the hardness and wear resistance of ceramics with the toughness and strength of metals. Known for their exceptional surface finish and durability, cermet inserts are widely used in finishing and semi-finishing applications where precision and consistency are critical.

At CNC Tools Depot, we stock a wide range of Cermet turning and milling inserts from global leaders like Korloy, Widia, Kennametal, Taegutec, Mitsubishi, and more, ensuring that machinists have access to the right insert for every application.

Key Features of Cermet Inserts

• High Wear Resistance – Longer tool life compared to conventional carbide inserts.

• Excellent Surface Finish – Delivers bright, smooth, and accurate surfaces.

• Stable Cutting Performance – Ideal for continuous and high-speed machining.

• Oxidation & Heat Resistance – Performs reliably at elevated temperatures.

• Low Built-up Edge (BUE) – Reduces material adhesion for consistent quality.

Applications of Cermet Inserts

Cermet inserts are highly valued in industries that demand fine surface quality and dimensional accuracy. Common applications include:

• Automotive industry – Precision finishing of engine components, shafts, and transmission parts.

• Aerospace sector – High-speed turning and milling of alloy steels.

• General engineering – Semi-finishing and finishing of cast iron and steels.

• Medical equipment – Machining components that require smooth, burr-free finishes.

• Tool and die making – High-precision finishing in mold and die production.

Types of Cermet Inserts

Cermet inserts are available in multiple geometries and grades to suit various machining needs:

1. Turning Inserts – CNMG, CCMT, VNMG, TNMG cermet inserts for finishing steel and cast iron.

2. Milling Inserts – SPMT, XOMT, and APKT types for high-speed milling applications.

3. Parting & Grooving Inserts – Designed for precise cutting and grooving with superior wear resistance.

4. Indexable Inserts – Reversible inserts that offer cost savings with multiple cutting edges.

5. Coated vs. Uncoated Cermet Inserts –

   • Coated Cermets: Provide higher wear and oxidation resistance.

   • Uncoated Cermets: Ideal for ultra-smooth finishing with minimal tool marks.
