Tooth pitch is measured in number of teeth per inch. For Combi (variable) tooth pitches, the two figures represent the highest and lowest number of teeth per inch in each group of teeth.



Regular Tooth Pitch

The distance between the teeth is constant throughout the blade.Suitable to cut solid materials on sawing machines with efficient clamping. Very effective on high alloy steels and exotic alloys.




Combi (variable) Tooth Pitch

Combi tooth pitch is based on groups of different pitches being repeated at regular intervals throughout the blade. The reduction of vibrations through resonance during cutting is the major advantage of this pitch. Sawing thin-wall hollow sections and material in bundles or with weak clamping are typical applications for this tooth pitch configuration.

For thin tubes (up to 8 mm wall-thickness) it is advisable to choose the toothing with 0° cutting angle.
