Failure to speed up or overheat the drill may cause it to become dull. At the same time, transitions to a larger diameter perfectly needle the drilled hole. Thanks to the spiral groove, the drilling is smooth, the chips do not stick, low cutting forces, the drilled material has less burrs and the tool has a longer life.
