Powerful special drill that should ideally be used for titanium base alloys as well as stainless, acid-resistant and heat-resistantaustenitic steels. It is also suitable for high strength steels with low ductility. Under certain conditions, these drills can be used for special alloys such as hastelloy, inconel and nimonic etc.
HSSE-Co 8:
Heavy-duty high speed steel with 8 % cobalt content.Extremely high ductility and outstanding heat resistance, for drilling holes in high strength materials, austenitic steel, for hot working etc. with a strength of up to 1100 N/mm².The titanium aluminium nitride coating offers high heat and oxidation resistance. Suitable for drilling hard materials without lubrication.
Max. application temperature 700 ºC
