what is a bi-metal saw blade?

Bi-
Metal blades are modern solutions for cutting hard metals including steel.
These blades are produced for many different types of saws, including steel saw, band saw, reciprocating saw, etc.
These blades are 10 times the length of traditional milling saw blades. Before bi-
The metal blade was invented, and the saw blade was completely cut with steel.
But for the past 35 years
Metal blades have been used in all the functions of cutting metal. Bi-
As the name suggests, the metal blade is made of two kinds of metal.
These two metals are usually welded together by different types of steel.
Spring Steel is usually used for backing and high
Speed steel grinding edge.
Since the welding process is usually done with a beam, the welding teeth last longer and are able to cut harder materials such as steel more easily. While bi-
Metal blades can be used in many different materials, the most commonly used double
Metal blades are designed to cut different forms of metal.
The determining factor is the tooth per inch;
Number of teeth per inch (tpi)
Used to cut hard material.
The addition of new metal, such as chromium, and new connection technologies such as diffusion connections, adds strength and helps reduce heat.
Heat, in particular, is a destructive factor in the blade that can break the teeth.
