Material Notes:
HS-105 high speed steel is a cobalt-modified M2 high speed steel in which the cobalt addition provides hot hardness that is intermediate between those of M2 and M42 high speed steels. The improved hot hardness makes the steel suitable for machining high-strength and prehardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous superalloys used in the aerospace, oil, and power generation industries. Typical applications for HS-105 high speed steel include twist drills, taps, milling cutters, reamers, broaches, saws, knives, and hobs.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
