We recommend you use fine-teeth blades in thin material and coarse teeth in thick material.
To increase the service life and wear-resistance of the saw blade, coolant like cutting oil (for steel or metals), turpentine (for aluminium) or water (for plastics or plexiglass) should be used appropriately.
The correct tooth pitch
The tooth geometry and the tooth pitch, which is a measure of the distance between the tips of the teeth, determine the cutting characteristics and the saw speed. 2-3 teeth should always be engaged with the material and this is the rule of thumb for deciding which tooth pitch to use.
