Metal drill fi 12.5 with cylindrical shank.
HSS12.5 mm metal drill bit. Professional NWKa twist drill with cylindrical shank with a drilling diameter of 12,5 mm. It is designed for professional metalworking, hard unalloyed tool steels, non-ferrous metals, metal alloys and plastics. It owes its increased hardness, wear resistance and resistance to heavy-duty work to the special high-speed steel HSS from which it was manufactured. It is a steel that increases the precision of drilling and also its efficiency. These types of cylindrical drills can be used for table, machine and numerical control machine tools. The 12.5mm metal drill has two center blades, ground edges, and a tip angle of 118 degrees. Precision drilling is possible and also efficient chip removal to the top of the hole. The high properties of high-speed steel also guarantee the long life of the drill and resistance to mechanical damage, which reduces the overall cost of machining.
