Quality Control


Manufacturing premium PDC cutters requires the direct use of high quality raw materialsCMM2
that are inherent in the final product (diamond, tungsten carbide, ultra-high purity metal powders and braze alloys), requiring strict Quality Control procedures. Manufacturing further requires the indirect use of several other raw materials and components. All sourced and manufactured to a carefully defined series of specifications. These raw materials and components then undergo a strict assembly and storage procedure before high pressure sintering. At GTD we maintain an effective Quality Management System to ensure rigorous control over all critical aspects of diamond synthesis (PDC and TSP diamond).

All our parts go through 100% visual and dimensional check. We also undertake the followDye Penetrant statistical sample QC checks:

  • Dye penetrant crack detection (NDTCMM)
  • Ultrasound (NDT)
  • Abrasion wear test (DT)
  • Microstructural and Elemental Mapping analysis (DT)

We are happy to provide certification and lot reference records with each customer order.
