Let’s share the relationship among tooth pitch, tooth height & gullet diameter. Follow below data will bring you a good cutting performance and save production costs.
Tooth pitch refers to the number of teeth per inch (tpi). 1 inch = 25.4 mm. Cutting thinner sections requires a finer pitch (more teeth per inch or 25 mm). Thick sections require coarser pitches (fewer teeth per inch or 25 mm).
Tooth height It should be as high as possible so that chips can store in the gullet. However, the height is limited since it is a function of the thickness of the blade, which determines the tooth’s rigidity. If the toothing is too deep to the thickness, it may vibrate and crack. In general, the height is roughly 11 times the thickness of the blade.
