tooth pitch	Correct tooth pitch – optimum performance
	Recommendation to cut solid material
	The choice of the right tooth pitch can be decisive to achieve the optimum performance to cut the relevant cross section. Choose either standard tooth with constant tooth pitch or variable tooth with unevently spaced teeth.	It is advisable to use variable tooth to cut problematic workpieces to reduce vibrations.

	Recommendation to cut tubes and structurals
	The choice of the right tooth has special influence on the cutting result on tubes and structurals.Variable tooth has proven to be the most favourable tooth form. Tooth pitches selected are depending on wall thickness and outer dimensions of tubes or structurals.	The recommendation shown here refer to single cuts. If two or more tubes or square pipes are cut at a time, double wall thickness to select tooth pitch.
