Warning: Any cutting tool may break or shatter under improper use. Always use of safety glasses and other appropriate safety equipments at all times in the vicinity of their use.
Cutting tools performance mainly depends on raw material composition, heat-treat process and precision tolerance.Among them material is the most important factor.
Different country developed its own steel code.
Following is a data that show major steel codes.
There are more than 1000 factories of cutting tools in china. Most of them can only supply one or two serial cutting tools. In another word, most of them are middle sized enterprise. No professional sales staff. And quality in China is complex, both poorly hand made tools and CNC professional making tools available. So when choosing partnesr in China, it is top important to find a professional man to communicate.
With development of China, more and more factories conduct ISO9000 serial quality management system. And some of them import advanced equipments from USA, Germany, Japan, Swiss and other developed countries. So quality is improving. In China, labor cost in relatively cheap and products' price is competitive in world tools market. So huge business opportunities exist in our country.
