HSS Kobalt M42 Bimetal band saw blades

HSS Kobalt M42 Bimetal band saw blades (article 90) are made joining two materials: HSS M42 cobalt high speed steel for the toothing, and special steel for the bearing band. These two materials are joined through a special welding that allows the bands to stand very high mechanical stress. Using 8% Cobalt and 10% Molybdenum steel for the toothing, it is possible to increase considerably speed and precision of the cut, and to reduce working time and cost. HSS Kobalt M42 Bimetal band saw blades are the best choice to cut steels and non-ferrous metals. They are suitable also for cutting the hardest metals, such as stainless steels, aeronautical alloys, tool steels and grade "D" alloys. If used correctly and with lubricating oil, they last very long.

HSS Kobalt M42 Bimetal band saw blades have standard toothing and positive rake angle. It is necessary to choose band saw blades having length of welded band compatible with the machine being used. We suggest choosing the pitch considering material and thickness of the workpiece. As a rule, working thinner materials requires more teeth: there should never be less than three teeth in contact with the workpiece. Having difficulty to choose between pitches, it is usually better to prefer the thicker one.

HSS Kobalt M42 Bimetal Stella Bianca band saw blades are available in different plays of welded band length (from 1330mm to 3660mm), pitch (3/4, 4/6, 5/8, 6/10 and 8/12) and height (13, 20, 27 and 34mm). Please check the tables below to know which models are available; if you need further information, please check our Catalogue.

HSS Kobalt M42 Bimetal band saw blades are available also per meter, according to the welded band length required by the machine being used, and in 5 pieces assortments.

For a correct and safe utilisation of our tools, please check the last tables for our suggestions about how to use the saws and the best cutting speed.

SUGGESTIONS FOR A CORRECT USE
1) always use the saws with a correct lubrorefrigerant. However, it is not necessary to use lubrorefrigerant to saw cast iron, brass and some non-metallic materials;
2) always check that saw and workpiece be correctly secured;
3) after some cuts with a new blade, it is necessary to check and correct the tension;
4) loosen the blade when the saw machine is not working, in order to prevent band breakage;
5) keep the ways of the blade as near as possible to the workpiece;
6) at the start, increase the cutting pressure gradually until the normal value is reached;
7) do not exceed the recommended cutting speed, according to the material being worked.
