Among the several points to consider, the material of the band saw blade should be primarily considered. The material of the band saw blade will largely contribute to the result of the cutting. For cutting soft, non-ferrous metals that do not contain aluminium, titanium, brass, iron and copper, use metal band saw blades that are made of carbon steel. For ferrous metals that are difficult to cut such as carbon steel, stainless steel and wrought iron, use bimetal saw blades. Bimetal blades are made of two different types of metal which are combined together to create a sturdy material for cutting. It is generally used for cutting titanium, aluminium castings and other hard metals.
For band saw machine, the shape of the tooth should also be considered in order to get the desired output. Just like buying blades for metal cutting equipment, the same consideration goes when buying band saw blades for metal cutting machines. For thin metal, use regular tooth shape while a hook tooth shape is ideal for thick metals. When you need to cut non-ferrous metal, a skip tooth shape should be used in order to prevent build up of material between the teeth.
As a general rule, choose metal band saw blades with the number of teeth per inch depending on the thickness of metal you intend to cut. Thick metals need blades that have lesser teeth for every inch while thinner metals need more teeth per inch for better cutting results. To get more information on the type of band saw blade that you would buy for your cutting requirements, research on the internet or ask your metal cutter operator for more ideas.
Lastly, one of the important things that you should remember when buying metal band saw blades is that there is no band saw blade for all types of materials. For precise cutting, ask skilled technicians for information. You can find different type of metal band saw blades on the internet and if you research good enough, you can even purchase one that is friendly to your pocket. Purchase several items at the same time to lessen your expenses. If you can find a supplier that offers free shipping, go for it but you should compare prices first to ensure that the free shipping offer would truly give you the savings that you look for.
