In the 1970s the coated carbide inserts (CVD coated exactly) were introduced in the market. The combination of a tungsten carbide substrate with a thin layer of coating resulted in a product that could achieve a cutting speed not far from the cermet with significantly higher toughness.

Cermet inserts (cermet cutting tools: Sandvik, Kennametal, GNRCERA, etc) were introduced in the 1950s. In those early days, carbide inserts were not coated and the cermet inserts enabled machining at much higher cutting speeds.

Cermet inserts (Kyocera, Sandvik, Kennametal, GNRCERA) offer a good solution for finishing applications in turning and grooving in stable conditions. In this situation, cutting speed can be about 10%-20% higher compared with coated carbide grades (CVD coated), still get a better surface finish.

Nowadays, the main roles of cermet inserts (cermet cutting tools) in the market include Kyocera, Sandvik, Kennametal, GNRCERA, Sumitomo, Tungaloy, Mitsubishi, Iscar, Seco.

Coated carbide inserts became popular in the industry. But cermet inserts have their advantages in some areas because of the features. Cermet inserts are used for finishing applications in stable conditions.

Cermet inserts (Mitsubishi, GNRCERA, Sumitomo, Iscar), or cermet cutting tools (Kyocera, Sandvik, Kennametal, GNRCERA, Tungaloy) offer a good solution for finishing applications in turning and grooving in stable conditions.
