Application

HSS Cobalt 5% metal 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 accurate splitpoint ensures it is self-centering and will make the holes without vibration.
In combination with cutting oil this will result in a very long tool life. Very suitable for cutting spot welds.
