Product name: JBWTL/Jingbawang cobalt-containing M35 straight shank general long twist drill
Material: high speed steel M35 containing cobalt
Processing range: suitable for processing general-purpose materials such as stainless steel. M35 is high speed steel containing 5% cobalt. Compared with high speed steel containing cobalt, M35 is cheaper and easier to process. Through appropriate heat treatment, high hardness, high red hardness and high wear resistance can be obtained. Performance, toughness and bending strength are not lower than ordinary high-speed steel, which can overcome early damages such as die edge collapse and chipping
