HSS Cobalt 8% core drills are made from alloyed high speed steel. With adding Cobalt the drills gets an extremely high hardness which enables them to cut in steel types which are difficult to cut. Full grinding during the production process results in a very sharp drill with high precision. The specially designed teeth profile ensures it will make the holes without vibration. In combination with cutting oil this will result in a very long tool life. Very suitable to use in alloyed steels and steels which are difficult to cut such as stainless steel (inox).
