M42 1.3247 T11342 HS2-9-1-8 Skh59 Steel High Speed Steel for Cutting Tools Including Twist Drills, Taps, Broaches Tools, Milling Cutters, Reamers, End Mills,

1 M42 Steel Introduction:

M42 high speed steel is a premium cobalt high speed steel with a chemical composition designed for high hardness and superior hot hardness. These properties make the steel an excellent choice for machining high-strength and pre-hardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous super alloys used in the aerospace, oil, and power generation industries.

HSS M42 steel exhibits excellent wear resistance by virtue of high heat-treated hardness (68 to 70 HRC), and the high cobalt content imparts the hot hardness. As such, the cutting edges on tools made from high speed steel stay sharp and hard in heavy-duty and high-production cutting applications.

2 M42 Steel Applications:

M42 steel can be used in conditions where the demand for hot hardness is important. Commonly used for cutting tools including twist drills, taps, broaches tools, milling cutters, reamers, end mills, bandsaw blades, cold work tools, and thread rolling dies.Back to Top

3 PROPERTIES:

HSS M42 high speed steel is highly Cobalt alloyed. The composition of speed steel makes for a good combination of toughness and hardness. By virtue of these well-balanced properties M42 high speed steel has come into wide use for all cutting tools.Back to Top
