HSS grade can be used to cover up to 80% of all applications. Offered in drill diameters of .719"-2.50", HSS blades are made from tough, fine grain tool steel (CPM-M4HSS) allowing them to be very forgiving in high production situations.
SC grade contains a higher cobalt content to provide higher wear resistance when drilling materials such as alloy and high strength alloy steel, high temperature alloys, and structural steels whose hardness is Rc 25+. Consult our recommended speeds and feeds table for complete application guidelines.
Solid carbide (C2 and C5) grades are also available upon request for drill diameters of .531"-1.375" for applications requiring the highest wear resistance. Consult our engineering department for details and information.
