How many teeth does a saw blade have for sawing wood?

When choosing the number of teeth for sawing wood, factors such as wood material, thickness and processing requirements need to be considered comprehensively. Here are some references:

1. According to wood material

Softwood: such as pine, fir, etc., the material is relatively soft, and a saw blade with fewer teeth, such as about 40 teeth, can be selected. This type of saw blade has a fast cutting speed and smooth chip removal, which can effectively improve work efficiency.

Hardwood: Hardwoods such as mahogany and sandalwood have high hardness and high density. It is recommended to use saw blades with 60 teeth or more. Saw blades with more teeth have more cutting edges, which can cut hardwood more finely, make the cutting surface smoother, and reduce tearing and burrs on the wood surface.

2. According to wood thickness

Thin wood: For thin wood with a thickness of less than 30mm, a saw blade with more than 72 teeth, such as a 96-tooth saw blade, can be selected. It has high cutting accuracy, can reduce vibration and deformation when cutting thin wood, and ensure the flatness of the cutting surface.

Thick wood board: For thick wood board with thickness over 30mm, saw blade with less than 72 teeth is more suitable, such as 40 teeth or 60 teeth saw blade. Large chip removal space and fast heat dissipation can prevent the saw blade from affecting the cutting effect and service life due to poor chip removal and overheating.

3. According to processing requirements

Rough processing: For rough processing with low requirements on cutting surface quality, such as cutting and cutting of wood, saw blade with fewer teeth, such as 30 teeth or 40 teeth saw blade, can be selected. It can quickly complete the cutting task and reduce the processing cost.

Fine processing: If it is fine processing with high requirements on cutting surface smoothness and precision for making furniture, handicrafts, etc., a saw blade with more than 60 teeth should be selected to make the wood cut surface smooth and smooth, reducing the workload of subsequent grinding process.
