Note: when drilling the speed must be adjusted according to the hardness of the material. The following applies: the higher the hardness, the lower the speed. The step drill speed should be set slightly lower than the speed recommended for the drilling with standard drill bits of the same diameter. When drilling in metal, we recommend using cutting paste or oil.
