How to choose carbide circular saw blade for cutting tool?

When choose circular saw blade for cutting, there are a number of circumstances should be considered. For example, type, thickness, cutting speed, cutting direction, feeding speed and width. Those things are attributed to selection of parameters like tooth shape and angle of  carbide circular saw blade for cutting tool ultimately. Selection of metal cutting circular saw blade is briefly introduced below.

Firstly, selection of metal cutting circular saw blade tooth shape

Tooth shape of carbide circular saw knife is divided into several parts, including left and right teeth, conical teeth, flat teeth, crescent teeth and other shapes. It is mainly based on character of raw materials to be processed. Left and right teeth are do for slitting and cross cutting all kinds of soft, hard and particleboard, it is equipped with anti rebound protection teeth are suitable for longitudinal cutting many types of materials.Left and right saw blades with negative front angle are usually used for sawing veneer due to their sharp teeth and exordinary quality.


Conical teeth are always used for grooving of panel saw. When processing wood-based panel with double veneer, grooving saw complete undercut processing, and complete sawing processing. So it has prevented debris collapse at saw mouth. Flat teeth are mainly applicated in processing common wood. Cost of this type is low, but cutting edge is rough. Combination of trapezoidal teeth and flat teeth also can obtain higher sawing quality without grooving saw blade, phenomenon pf veneer cracking will not occur during processing. It is fit for processing various double faced wood-based panels.

Secondly, choice of serration angle

Angle parameter of saw tooth part is complicated, choose angle parameter of carbide circular saw knife correctly is of vital importance, it determines quality of processing. The most important angle parameters are front angle, back angle and wedge angle. Front angle mainly affects force consumed by sawdust. The bigger the rake angle is, the better the cutting sharpness is, the lighter the processing is and the less effort is saved in pushing.

Generally, selection of carbide circular saw blade for cutting tool is mainly related to material of workpiece. When material of workpiece is soft, large front angle is recommended. Otherwise, smaller angle is prefer.
