43708 On-Edge Solid Carbide Threading Insert, C520 Grade, Uncoated (Bright) Finish, TPMA Style, Right-Hand, 4-20 UNF External x 4-20 UNC Internal (Pack of 10)

Cobra Carbide on-edge carbide threading insert. Is a 10 degrees positive rake insert with a straight through hole. Positive rake insert is ideal for internal threading. General purpose grade designed for cast iron and non-ferrous materials. Can also be used for machining 200 and 300 series stainless steel. Provides excellent wear resistance. Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications.
