Cutting tools such as gear hobbing, worm milling cutters or chain sprocket gear hobbing, etc. are often complex in shape; therefore, they are often produced with complete body shape and with high speed steel. Thus, this results in low production efficiency, low service life time of cutting tools as well as low accuracy and quality.

To avoid these limitations, our company has been implementing a strategic project on design and production of cutting tools with carbide inserts. Based on the company's experienced researchers and co-partners including professors and researchers in Thai Nguyen University of Technology, the project has achieved remarkable success.

This project started by trial production of chain sprocket gear hobbing with carbide inserts in 2007. This is a part of the nationally funded research carried out by Dr. Nguyen Van Hung, the Vice-President of Nhan Chinh MEC. company. This project has been evaluated successfully. Consequently, Nhan Chinh MEC. has been continuously expanding research and applications in other cutting tools with carbide inserts such as drilling tools and capabilities in improving accuracy of machined products as well as increase of service life and productivity of tools.
