M-2 (DIN 1.3343)
For all metal-cutting tools for roughing or finishing, such as twist drills, all kinds of milling cutters, screw taps, screw dies, broaches, reamers, countersinks, thread chasers, segments for circular saws, shaping tools and woodworking tools. Also highly suitable for cold-forming tools, such as cold extrusion rams and dies, as well as cutting and precision cutting tools, plastic moulds with elevated wear resistance and screws.
Applications:Standard high-speed steel grade. High toughness and good cutting power owing to its well-balanced alloy composition; thus suitable for a wide variety to applications.

M-42 (DIN 1.3247)
M-42 is a molybdenum-chromium-vanadium-tungsten high speed steel alloy with an additional 8% cobalt. It is widely used in metal manufacturing because of its superior red-hardness as compared to more conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M-42 is also less prone to chipping when used for interrupted cuts and cost less when compared to the same tool made of carbide.

T-42 (DIN 1.3207)
High Speed Steel T 42(HSS, T42) have been used as high performance cutting and rolling tools. Tools structural application is a combination of high strength, wear resistance, high hardness together with toughness, fatigue resistance and thermal re¬sistance [1,4 Recent research on extending tools life and improving structural performance are being carried out through manufacturing process, heat-treatment, surfacing process and alloying elements.
SPS technique has the merits of faster heating rates, shorter sintering times and high density [31. During SPS process, alloy powders in a graphite die are pressed uniaxially a D.C. pulse voltage is applied and the heating is accomplished by electric discharge between particles. However, the research for the T42 using SPS was not carried out generally. Characteristic Properties: Heat treatable alloy. Very good machining characteristics. High strength alloy with a strength slightly higher than 2014(A) and 2017A and 2030. High fatigue strength. Suitable for welding only by resistance welding. Corrosion resistance only with cladding or other protection.
