  • Thermal Stability

    Unmatched Thermal Stability means reduced Cycle Times and Higher Speed Capability vs competitive ceramics (SiAlON, Si3N4, Al2O3, etc.) 

  • Wear Resistant

    TCT focuses only on advanced materials. SBN & TCT-25 Grades are the hardest materials in the world second only to Diamond. High Hardness means better wear resistance even in the most abrasive workpiece materials.

  • Fracture Resistant

    Enhanced ceramic matrix composites with CBN & SiC whiskers creates long range force distribution resulting in a tough substrate that can handle the most aggressive machining parameters. 

  • Versatility

    "CBN & Ceramics can't take interruptions" 

    Challenge Accepted. An objection of the past. Interrupted turning, indexable milling, etc. TCT’s SBN Grades & Ceramics are up to the task. Bring your applications, let us apply our material expertise.
