First, woodworking saw blades
It is used to saw wood and needs to distinguish the tooth shape of the saw blade. The tooth shape of the woodworking saw blade generally includes: left and right teeth (alternating teeth). The tooth type is selected, which not only improves the high sawing efficiency, but also is not easy to burn and chip. For other panel saw blades, some of the tooth types are flat teeth.
Second, cut aluminum saw blade
It is used to saw aluminum, generally using ladder flat teeth, also known as high and low teeth or large and small teeth. It is characterized by the fact that it is not easy to break teeth when sawing, cracking teeth, precise sawing, smooth cutting surface and no burr.

What is the difference between 40 teeth and 60 teeth? The 40 teeth have a small frictional force, which saves effort and the sound is small, but the 60-tooth cut is smoother. General woodworking uses 40 teeth. The price is the same, just to make the sound small, it is thicker, but the thin quality is better. The more the number of teeth, the smoother the sawing profile, and the sound will be smaller if your machine is stable.
Note on the use of saw blades:
1. The saw blade cannot be used immediately. It should be laid flat or suspended by the inner hole. The other saw blades should not be stacked with other objects or feet, and should be protected against moisture and rust.
2. When the saw blade is no longer sharp and the cutting surface is rough, it must be repaired in time. Grinding does not change the original angle and destroys the dynamic balance.
3. The inner diameter correction of the saw blade, the positioning hole processing, etc. must be performed by the factory. If the processing is poor, it will affect the product use effect, and may be dangerous. The hole expansion principle should not exceed the original hole diameter of 20mm in order to avoid affecting the stress balance.
