ABSTRACT:
There is provided a method of coating cutting tool inserts by CVD methods with a completely covering coating. During the coating step, the inserts are resting in contact with the support in only a few tiny spots and sufficient space is allowed around each insert to ascertain optimum coating conditions. In a preferred embodiment, each insert rests on a peg allowing a rational production in larger scale and fully automatic CVD loading.
