Engineering Rods

p1426-01●Purposes of Use : Drills and Endmills
●Shape : Solid Formed Rod

 

●Feature :  Twice-sintered material. After pre-sintering, the material is molded into a
      shape similar to a final product, and then sintered fully, with the purpose
      of reducing the cost of processing with a diamond wheel. This is mainly
      used for multistage burnishing drills, etc.
