PCD is rated by the number of micro grains
                                    of polycrystalline diamond used in the coating process, ideal for milling and rough
                                    cutting of aluminum alloys, machining of high silica alumina alloys, metal matrix
                                    composites, tungsten carbide and ceramics, because of the excellent abrasion resistance
                                    and thermal stability. We can provide customer specific engineered products for
                                    each tooling application. 
  
        PDC (Polycrystalline Diamond Compact) PDC
                                    is mainly used in the mining and oil/gas industries due to its high impact resistance
                                    and exceptionally low wear rate. Besides the compact, we also provide the technical
                                    service for use in each stage of the usage process.
