What is the difference between the number of saw blade teeth
Jun 17, 2023
When using a saw blade, you will find that the saw blade not only has a size, but also has more or less teeth of the same size saw blade. Why is this design, how much is better or less?
In fact, the number of saw teeth is related to whether the wood you want to cut is cross-cut or longitudinal.
We can do an experiment, cut wood with a knife, and you will find that most of the cross-cuts are particles, while the longitudinal cuts are strips. The wood is essentially a fibrous tissue, and it is reasonable to have such a result.
For multi-tooth saw blades, at the same time, you can imagine the situation of cutting with multiple knives. The cutting is smoother. Black), the sawdust excretion is slower than the number of teeth. It is suitable for scenes with high cutting requirements, and the cutting speed is appropriately slowed down, suitable for cross cutting.
There are few saw teeth, but the sawed surface is relatively rough, the distance between the tooth marks is large, and the sawdust removal speed is fast. It is suitable for rough processing of cork, and the sawing speed is fast. There are advantages to slitting.
If you use a multi-toothed cross-cutting saw blade to cut longitudinally, because the number of teeth is too large, it will easily cause poor chip removal, and the speed may cause paste sawing and pinch sawing.
It is easy to create a hazard when a pinch saw occurs.
Plywood, MDF and other artificial boards, after processing, the direction of the wood grain has been artificially changed, losing the characteristics of forward and reverse cutting, cutting with a multi-tooth saw blade, slow down and move smoothly, use a saw blade with fewer teeth, the effect will be much worse.
If the wood grain is cut obliquely, it is recommended to use a multi-tooth saw blade, and a saw blade with fewer teeth may pose a safety hazard.
To sum up, if you encounter the problem of how to choose a saw blade in the future, you can cut more obliquely, choose your sawing direction to decide what kind of saw blade to use, the saw blade has more teeth and less teeth, and choose according to the direction of wood fibers , Choose multi-tooth for oblique cutting and cross-cutting, choose few teeth for longitudinal cutting, and choose cross-cutting for mixed wood grain structure.
