Non-alloyed construction steel, non alloyed case hardened steel (< 400 N/mm² or < HRB 69) : Most suitable
Non-alloyed construction steel, non alloyed case hardened steel (400-800 N/mm² or < HRC 21) : Most suitable Flatter twist angle creates smaller chippings, ideal for drilling harder steels ie: stainless steel.
