Sintered handle

　　The main advantage of the sintered shank is the high precision of the product. The concentricity of each shank is 0.003MM. There are 4 additional screw holes for precise dynamic balance. The body of the shank is made of special heat-resistant steel, which fully guarantees the shank. Ultra-high rigidity and durability, and fully suitable for induction heat shrinking machines; each tool holder has a service life of more than 3,000 times and a chip hole is reserved on the flange of the shank, which is very suitable for automated production lines and In the unmanned workshop, the heating time can be completed in only 4-5 seconds.
