Selection of Sawtooth Angle of Tungsten Carbide Saw Blade

The sawtooth angle affects the cutting performance of tungsten carbide saw blade. Wherein, rake angle, clearance angle, and wedge angle have the greatest influence on the cutting effect.

1. Rake angle - Generally between 10-15°; the larger the rake angle, the better the sharpness of the sawtooth, and the faster the cutting. Generally, when the material to be processed is softer, choose a larger rake angle, otherwise choose a smaller rake angle.

2. Clearance angle - The angle between the sawtooth and the processed surface; generally, 15°; to prevent friction between the sawtooth and the processed surface; the larger the clearance angle, the smaller the friction and the smoother the processed product.

3. Wedge angle - Cannot be too small; it plays a role in maintaining the strength, heat dissipation and durability of the saw tooth.

The sum of rake angle, clearance angle and wedge angle is equal to 90°.
