An Overview of Bi-Metal Bandsaw Blades

July 14, 2021

When it comes to choosing the right bandsaw blades, there are many options to consider. One of the most important factors is the type of material the blade is made from. Bi-metal bandsaw blades are popular because of their strength and versatility.

In today’s blog, we will be going over what sets bi-metal blades apart:

What is Bi-metal?

Bi-metal, as the name suggests, is a material constructed out of two kinds of metals. However, they are unlike alloys. In alloys, two or more metals are mixed together to create a new alloy. Bi-metals bring two types of metals together, but instead of mixing them together, these two metals are stacked on top of one another and then welded together.

Why Bi-metal?

The strengths of bi-metal bandsaw blades are unique to their construction. Bandsaw manufacturers have identified that regular carbon blades start to wear down quickly over time, and furthermore, do nt have much flexibility. The solution is to use two different kinds of metals together to give blades the ability to stay sharp longer while having a flexible body. As such, bi-metal blades have high speed steel-constructed edges and bodies made of spring steel—two different materials which give durable sharpness and flexibility without breakage respectively.

When to Choose Bi-metal?

Bi-metal bandsaw blades are the most common type of blade used in various applications. In general, they are perfectly suited for cutting the following materials:

  • Carbon steel
  • Tool steel
  • Structural steel
  • Stainless steel
  • Pipes/tubing
  • Die steel
  • Angles
  • Flat stock
  • Mixed metal applications

Typically, bi-metal blades are thought of as being able to cut stronger, metal-based materials than carbon steel blades can. However, for even stronger kinds of metals, bi-metal blades are not as suitable as carbide saw blades. Indeed, there are three main types of bandsaw blades: bi-metal, carbon steel, and carbide saw, and their cutting strengths and applications all differ significantly.
