  • Page 8 7.5. Choosing the saw blade Choose a toothing that is appropriate to the workpiece being processed. Ideally, at least 3 teeth should be in action at the same time. The toothing should not be smaller than necessary, as the cutting speed is reduced if there are too many small teeth working on the workpiece simultaneously, which causes the saw blade to wear more quickly, and makes the cuts crooked and distorts them.
  • Page 9 7.6 Cutting speed selection The general rule is the harder the material being cut, the slower the blade speed. 25 - 30 m/min (Position 1) for stainless steel, alloy steel and bearing bronzes. 40 - 50 m/min (Position 2-3) for mild steel, hard brass or bronze. 60 - 80 m/min (Position 4-6) for soft brass, aluminum or other light materials.
