How to choose carbide saw blades correctly

Carbide saw blades are the most commonly used cutting tools for wood product processing, and their quality is closely related to the quality of processed products. The correct and reasonable selection of carbide circular saw blades for wood is of great significance for improving product quality, shortening processing time, and reducing processing costs.

Tungsten carbide circular saw blades include the parameters, such as the saw tips grade, the material of the body, the tooth shape, the angle, the diameter, the number of teeth, the thickness, the bore size, and other parameters. These parameters determine the processing capacity and cutting performance of the saw blade. Today I will share some tips when we choose a tungsten carbide saw blade, the following parameters of the saw blade should be selected correctly according to the needs.

Choose carbide tips grade
Because tungsten-cobalt-based cemented carbide has better impact resistance, it is more widely used in the wood processing industry. The commonly used model in wood processing is YG8-YG15.

Selection of saw blade tooth type
The tooth type of the circular saw blade is divided into left and right teeth, tapered teeth, flat teeth, trapezoidal teeth, crescent teeth, etc. In actual use, the choice is mainly based on the type of raw material being sawed.
The left and right teeth are suitable for opening and horizontal sawing of various soft and hard materials and particle boards.
Tapered teeth are often used in the slot saw blades of panel saws.
Flat teeth are mainly used for the sawing of ordinary wood. This kind of saw blade has a lower cost but is a rougher saw.
The combination of trapezoidal teeth and flat teeth can also obtain high cutting quality without slotted saw blades, and there will be no veneer cracking during sawing. It is suitable for sawing various double-veneer wood-based panels.

Choice of saw teeth angle
The angle parameter of the saw teeth part is more complicated, and the correct selection of the angle parameter of the saw blade is the key to determining the quality of sawing. The most important angle parameters are rake angle, rear angle, and wedge angle.

The number of saw teeth
Generally speaking, the more teeth, the more cutting edges can be cut per unit of time, and the better the cutting performance. However, the more cutting teeth, the more cemented carbide is needed, and the higher the price of the saw blade. However, the teeth are too dense and the gap between the teeth and The smaller chip capacity will easily cause the saw blade to heat up.

The thickness of the saw blade
In theory, we hope that the thinner the saw blade is, the better, but the sawing is a consumption. The material of the saw blade and the process of manufacturing the saw blade determine the thickness of the saw blade. When choosing the thickness of the saw blade, the stability of the saw blade and the material to be cut should be considered.

Choice of bore size
The bore size is a relatively simple parameter, which is mainly selected according to the requirements of the equipment, but to maintain the stability of the saw blade, it is best to choose a larger bore size for the saw blade above 250mm.  Regardless of the size of the hole, it can be modified by a CNC lathe machine or a wire-cutting machine.

The choice of cemented carbide saw blades is related to so many parameters. It seems very complicated. As long as you find a suitable professional supplier, it is easy.
