I Technical information circular saw blades
I Diagram for cutting speed

The scale shows a guideline of cutting speeds for HW saw blades in relation to the processed material. When defining the cutting
speed range for composite materials the most difficult material always has to be chosen for definition. On average chip removals
(f ) of 0,075 mm should be chosen for larger cutting heights and 0,15 mm for smaller cutting heights.

The maximally admissible rpms (n) up to ... given on the tools, may under no circumstances be exceeded! They mark the
safety limit. They are not identical with the rpm providing the best possible economic efficiency.
