We profile ground (not formed) our Full Concave Solid Carbide Cutters with alternating tooth design for a rounder, more free cutting concave cutter. Our Full Radius, Full Concave Corner Rounders feature alternating tooth design, solid carbide, and profile ground like our other corner rounders. They have a slight flare at each end to avoid gouging the part. Special orders in 4-6 working days. Proudly made in the USA by AB Tools, Inc.
