It is not possible to coat brazed carbide tipped tools or HSS cutting tools because the temperature of the coating process (1,500° F / 815.5° C) would damage these materials. It is also not possible to coat solid carbide tools that have been previously coated nor is it possible to re-coat a diamond coated tool.

The selection of the carbide grade for manufacturing the tool is a most important consideration because it has a significant effect on the efficiency of the coating procedure and consistency of the coating adhesion. DTC has much experience with a number of carbide grades that are good choices for DiaTiger® Diamond Coating. [View Recommended Carbide Grades]
