Circular saw blades are widely used in the processing of wood, plywood, MDF, artificial marble, plastics, aluminum and other materials. The right circular saw blade can improve product quality, shorten processing cycle time and reduce processing costs.

4 Buying Tips on How to Choose Circular Saw Blade

Jun. 30 , 2022

Circular saw blades are widely used in the processing of wood, plywood, MDF, artificial marble, plastics, aluminum and other materials. The right circular saw blade can improve product quality, shorten processing cycle time and reduce processing costs.

This article will discuss several aspects of how to choose circular saw blade to help you better understand and utilize this tool.

How to Choose Circular Saw Blade

Selection of Materials

1. Alloy tool steelCircular Saw Blades

Compared with carbon tool steel, its wear resistance is stronger and its processing performance is better. The heat deformation resistance temperature is 300℃-400℃, which is suitable for manufacturing high-grade alloy circular saw blades.

2. High-speed tool steel

It has good hardenability, hardness and stiffness. It has poor heat deformation resistance and is an ultra-high strength steel. Stable thermoplasticity, suitable for manufacturing high-grade ultra-thin saw blades.

3. Carbon tool steel

High carbon content and high thermal conductivity. However, its hardness and wear resistance drop sharply when affected by the temperature of 200℃-250℃. High heat treatment deformation and poor hardenability. It is an economic material for tool making.

4. 65Mn spring steel

Good elasticity and plasticity, economical material. Heat treatment hardenability is good, its heating temperature is low and easy to deform. It can be used for saw blades with low cutting requirements.

Selection of Saw Teeth

Tungsten carbide inlay saw teeth have a significant impact on sawing performance. Cobalt tungsten carbide has better impact resistance. It is more widely used in the material processing industry. The impact toughness and bending strength of saw teeth are improved by increasing the cobalt content. However, the hardness and wear resistance are decreased, and the choice should be made according to the actual situation.

Generally speaking, the more teeth, the more cutting edges per unit time and the better the cutting performance. However, the higher the number of teeth, the more carbide is needed and the higher the price of the saw blade. If the saw teeth are too dense, the chip capacity between the teeth becomes smaller, and it is easy to cause the saw blade to heat up.

In addition, the number of teeth is too much, in the case of improper feed fit, the cutting volume of each tooth will be small. Will intensify the friction between the saw blade and the workpiece, affecting the service life of the saw blade. Usually, the tooth pitch is 15-25mm. Choose circular saw blade with reasonable number of saw teeth according to the material you’ll be cutting.

Different Circular Saw Blades

Selection of Diameter

The saw blade diameter is related to the sawing equipment used and the thickness of the workpiece to be sawed. Under the same working conditions, the reduced power encounter angle of a small diameter circular saw blade can reduce the consumption of cutting power.

Often the choice of a small diameter circular saw blade also leads to a reduction in the amount of feed per tooth can improve the quality of the cut. Reduced sawing volume can reduce wood and energy consumption. Improving the dynamic stability of the saw blade.

Therefore, in order to improve the stability of the saw blade and reduce the sawing loss, the smaller the diameter of the saw blade the better in order to meet the requirements of the sawing thickness. Don't increase the diameter of saw blade unnecessarily.

After understanding how to choose a circular saw blade, hopefully your cutting work will go better. SINOTOOLS offers a wide range of sizes of circular saw blades and other cutting tools. If you have any questions or purchase needs, please feel free to contact us.
