Cemented carbide has high hardness, strength, wear-resistance and corrosion resistance. It can be used to manufacture cutting tools. It is widely used in military, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communication, construction and other fields.
Since stainless steel is not easy to rust, and has the characteristics of good heat resistance and high strength, it is widely used in the manufacture of modern industrial products. However, due to the poor thermal conductivity of stainless-steel during processing, serious work hardening of the material, and easy stacking of chips, the processing of stainless steel has always been a major problem for technicians and R&D designers. In order to solve these problems, carbide drill bits for stainless steel has been developed to help you process stainless steel efficiently. Drilling stainless steel with carbide has the following advantages:
(1) Suppress work hardening: Pay attention to the sharpness of the cutting edge to improve the life of tool.
(2) Solve the problem of chip breaking: the new groove design can realize the stable and consistent small segmentation of chips. The design of inner cooling oil hole further helps to remove chips, so as to achieve faster processing speed and longer service life, which is suitable for a wider range of processing fields.
(3) Reduce cutting temperature: the special cross cutting edge design can reduce the friction area with the processing material, so as to reduce the friction heat; the new inner cooling oil hole shape can greatly increase the cutting fluid flow rate and quickly dissipate the cutting heat.
(4) Inhibition of chip dissolution: A coating process is applied to the surface of the cemented carbide drill bit. After the coating is used, the drill bit has excellent dissolution resistance and adhesion ability, which can effectively prevent the wearing of tool.
