What are the key differences between the different types of Bi-metal bandsaw blades?

Posted on 4th February 2020

Making sure that you choose the correct bandsaw blade type for your next cutting application can sometimes be a challenging task; with so many variations on the market, it’s becoming harder and harder to know which blade type will be able to provide you with the best results. This is an issue of particular prominence for those looking to distinguish the difference between the different types of bi-metal bandsaw blade, as all can be used for a wide range of different cutting applications.

Below, we aim to discuss the main difference found between the bi-metal bandsaw types, helping you to identify the blade best for your cutting application.


M42 Bi-Metal Band Saw Blade

The M42 Bi-Metal bandsaw blade is best used within cutting applications upon a number of varying kinds of general-purpose metals and is great when used within stainless steel projects, as well as a range of other steel types. This is a blade type that is able to provide a great level of cutting accuracy to any application, reducing your cutting times by up to 50%; this thus works to make the use of this industrial saw blade a highly efficient option to any users. The M42 Bi-Metal saw blade can be used within a wide range of applications, including:

  • Aluminium
  • Alloy Steels
  • Carbon Steels
  • Stainless Steels
  • Structural Steels
  • Tool Steels
  • Non-Ferrous Metals

This blade type is ideals for use upon traditionally hard-to-machine metals, making it the ideal choice for those who may have struggled to find the ideas bandsaw for metal cutting applications in the past.


M51 Bi-Metal Band Saw Blade

M51 Bi-Metal bandsaw blades are another option providing great results when used within stainless steel cutting applications, offering up great results due to the fact that these are industrial saw blades designed for use upon harder to cut materials. M51 blades tend to, on average, hold a much longer operating life compared to other options on the market, also providing a higher level of cutting accuracy, making this blade choice a great option for use within projects that require a heightened sense of precision. The M51 Bi-Metal blade can be used within the following cutting applications:

  • Stainless Steels
  • Inconel
  • Nimonics


M66 Bi-Metal Band Saw Blade

The M66 Bi-Metal bandsaw blade is ideal within applications using structural steels, offering up both excellent results and performance. The use of M66 Bi-Metal blades works to reduce the risks of teeth stripping, a wider set also reduces the changes of jamming, therefore resulting in a quality performance and longer saw blade life. This saw blade type is a great choice to opt for within cutting applications that involve:

  • Hallow Sections
  • Structural Steels
  • I Beams
  • Fabrications


To conclude, while there is a vast amount of different industrial saw blade types to choose from when trying to find the option most suitable for your application, knowing your requirements and what you’re looking to get out of your project is vital in helping you to make the best decision.
