APT, the main raw material for the manufacture of diamond inserts, is the main intermediate raw material and market for the production of tungsten products. The main producing areas for tungsten are in the Alps, the Himalayas and the Pacific area. China has 60% of the tungsten deposits, the international market due to shortage of raw materials, APT prices in recent years, nearly ten times the growth. While the increase in costs will eventually be passed on to the end users of the tool.

Currently the world's relevant research institutions for such cases, ongoing active research, the main research program is to make the greatest possible reduction in the amount of tungsten in the tool, the main method is only a key part of the tool using tungsten. With the new materials and new technology research and application, ceramics, cubic boron nitride, diamond blades, these cutting tool materials will have better prospects for development.
