Using the best carbide reputable companies in the world and selecting the suitabe carbide grade and selecting suitable steel ,The basic material used is the least risk

In addition, the heat treatment of steels in salt baths increase Uniformity microstructure and the risk of possible cracks caused by the heat treatment may lead to a minimum.

Hardness at all stages of the heat treatment is done 

Dimensional control during machining operations and at the end by micrometers precision of 2 microns will be done 

        Surface quality after polishing will be re-inspected.
