9.The advantages for Telfon Coating:
1). Heat-resisting, steady perdormance at high working temperature
2). Anti-sticking, high sliding for better chip removal
3). Better-corrodion resistance
4). With excellent adhesion properties with steel shank
5). Non-toxic
6). High hardness surface
7). Resistance to impact shocking
8). Good insulating ability and wear-resisting
