M2 high speed steel round bars have international standards. Their diameter is approximately from 10mm to 300 mm. The grades that we prefer in our company are AISI M2 (DIN -1.3343) and so on. They belong to the group of tungsten molybdenum alloy. The uses of M2 high speed steel round bars are in the making of cold cutting tools, woodworking tools, etc. The actual purpose of these high steel round bars is to attach the parts of pipes from the middle. Such connections need to be very tight and firm. They can also be used in pressure valves as the plug-in for resisting pressure. They have the feature of double leak proof. These bars are manufactured with high-quality materials that offer top-notch specifications and properties.

How to use HSS M2 round bar weight calculator?
You need to know the diameter and length of the bar you wish to determine the weight of in order to utilise an HSS M2 round bar weight calculator. Both of these dimensions will normally have input areas on the calculator. Simply click the “calculate” button to obtain the bar’s weight after entering the bar’s diameter and length. You may also select the unit of measurement for the diameter and length on some calculators (e.g. inches, millimetres). Given that the density of the M2 round bar can differ based on the manufacturer and supplier, the calculator may additionally let you select the material’s density. Once you have entered all the necessary data, the calculator will give you the weight of the bar in the desired unit of measurement (e.g. pounds, kilograms).
What are industrial uses of M2 hss rod?
M2 high-speed steel (HSS) rods are used in a wide range of industrial applications due to their exceptional wear resistance, hardness, and high heat resistance. Some common industrial uses of M2 HSS rods include cutting tools such as drills, taps, milling cutters, and reamers. M2 HSS rods are also used to make punching and stamping die, and measuring tools such as micrometres, gauge blocks, and dial indicators. They are also used to make shear blades for cutting sheet metal and other materials, cold work tools such as punches, chisels, cold-heading die, and broaching tools for cutting gears, keyways, and other internal profiles. M2 HSS rods are also used to make woodworking tools such as planer knives, saw blades, and router bits, and in other industrial applications such as in the aerospace and automotive industries for gears, spindles, and shafts.
