When looking to purchase metal bandsaw blades, there are a few factors to consider to ensure you choose the right blade for your needs. Metal bandsaw blades come in a variety of sizes and shapes, and can be made from different materials like high-speed steel or carbide. It’s important to consider the type of metal you will be cutting, the thickness of the metal, the size of the bandsaw machine you will be using, and the desired finish of the cut.

It’s always recommended to consult with a professional or consult with the manufacturer to make sure you choose the right blade for your specific application.

Some different types metal bandsaw blades include:

• Carbon steel
• Aluminium
• Alloy
• Stainless steel
• Cast iron
• Bi-Metal M42

There are various types of metals inside the blade itself. Such as, tungsten steel, carbide deposits, M42 steel and spring steel. 

So, how do I know which metal bandsaw blades to purchase? This will depend on the size and type of material. Certain types of metals cut certain types of materials, depending on the hardness level. This means, when choosing your blade it’s important to take into account what you’ll be cutting and what your machine can withstand.

For example, Bi-Metal M42 can only cut up 44HRC. Anything higher requires a different blade level, such as the Bi-Metal M51. Also known as the Bi-Metal Extreme. This blade can cut up to 55HRC. 

TIP: The width of the blade needs to be adjusted depending on the thickness of the material.
