What does a bimetal band saw mean?

Bimetal band saw blade is a kind of band saw blade with bimetal structure. Its material is mainly made of two kinds of metals: teeth and back. It can be used in conjunction with any type of band saw, and is usually used to cut ordinary ferrous metals, alloy tool steels, alloy structural steels, die steels and nonferrous metals, and to cut frozen fish, frozen meat and other frozen objects by selecting appropriate tooth profiles. Bimetal band saw blade can also be used as woodworking saw blade to cut wood, but it needs to process and make a lot of serrations. Let's see where bimetallic band saw blades are mainly used. 1. What does a bimetallic band saw mean?

Bimetallic band saw blade mainly refers to the metal cutting band saw blade with high-speed steel or other high-performance steel as the tooth tip material and low-alloy spring steel as the band saw material.

The material of bimetallic band saw blade is mainly composed of teeth and back metals welded by electron beam (or laser). Its material characteristics are bimetallic structure: B3 18 backing, with high fatigue strength; M42 tooth material contains 8% cobalt, and its tooth hardness is HRC67-69. It has the characteristics of high wear resistance, high red hardness, and long service life.

2. Where is the bimetallic band saw blade mainly used?

Bimetallic band saw blades are widely used, which can be used with any type of band saw and suitable for continuous sawing of almost all types of metals. The main uses of bimetallic band saw blades are:

1, cutting ordinary ferrous metals, such as cast iron, cast steel, rolled round steel, square steel, pipe and section steel.

2. Cutting hard and sticky metals, such as alloy tool steel, alloy structural steel, die steel, bearing steel and stainless steel.

3, cutting copper, aluminum and other non-ferrous metals.

4. Choose proper and reasonable tooth profile (jumping teeth), which can also be used to cut frozen fish, frozen meat and other hard frozen things.

3. Can a bimetallic band saw cut wood?

Yes, but it needs to be handled.

Woodworking saw blades are different from ordinary band saw blades. The biggest difference is that in the tooth profile, woodworking saw blades mostly adopt large tooth slots with equal teeth to contain and remove chips. It is not suitable to cut wood with ordinary bimetallic band saw blade, but it can also be used to cut hard and precious wood such as mahogany, oak and iron pear if it is treated with some special techniques, such as bimetallic band saw blade with a large number of serrations.

In addition, the bimetallic band saw blade used for cutting wood should pay attention to the material selection. Generally, carbon steel and high speed steel can be used for soft wood. Hardwood should use high-speed steel and cemented carbide; Precious wood such as mahogany needs cemented carbide saw blades to avoid burning the wood surface when the saw blades run at high speed.
