Ceratizit Offers Inserts Optimized for Steel Turning

Ceratizit has introduced three standard, coated-carbide, ISO-P steel insert grades that it says provide up to 20% longer tool life when compared to previous generation grades. The inserts are engineered for increased productivity, featuring advanced substrates, geometries and the company’s Dragonskin multilayer coating for lower heat and less tool wear.

The gold-colored TiN outer layer of the Dragonskin multilayer CVD Ti(C,N)/Al₂O₃/TiN coating acts as an indicator to prevent insert waste and detect wear. The inserts also undergo a mechanical post-coating treatment designed to produce beneficial, residual stress in the coating that results in increased process security.

Each of the three grades are engineered for optimizing specific production scenarios. The CTCP115-P (ISO P15) grade has enhanced resistance to high temperatures and is well-suited for use at higher cutting speeds in smooth, continuous cuts in stable cutting conditions.

The CTCP125-P (ISO P25) universal steel-cutting grade balances toughness and wear resistance. It is designed to offer reliability in turning operations ranging from finishing to rough machining. 

The CTC135-P (ISO P35) is a tough carbide grade well suited to lower cutting speeds, interrupted cuts and unstable machining conditions.
