The mostsuitable speed depends on the material involved.We recommend that you carry out a fewpractical tests beforehand.Tip: You will always find these two basic guidelineshelpful:1. Large drill diameter = lower speed whilstsmaller drill diameter = higher speed2. Hard material = lower speedSelecting the directionof rotationCaution!
