Cobra Carbide on-edge carbide threading insert. Is a 10 degrees positive rake insert with a through hole countersunk on two sides. Positive rake insert is ideal for internal threading. Designed for heavy roughing to semi-finishing of all steels. 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.
