• HSS Cobalt 5% metal drills are made from alloyed high speed steel. • Cobalt gives the drills an extreme hardness factor, enabling them to cut the toughest of steel types. • Full grinding during the production process results in a very sharp drill with high precision. • The accurate splitpoint ensures self-centering for accurate and stable drilling. • In combination with cutting oil this results 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). • DIN338. • Right hand. • Type N. • 135º cutting edge. • w/ Splitpoint. • Fully ground. • M35 steel. • 5% cobalt alloy. • Cylindrical shank.
