This high-speed steel (HSS) intermediate tap, also known as a second tap, is manufactured for cutting precise internal threads to the Unified National Coarse (UNC) standard, sized 5/8" x 11 TPI (threads per inch). With a medium lead-in taper, it balances ease of cutting with accuracy, making it ideal for both through holes and blind holes. It is generally used after a taper tap and before a bottoming tap in a complete set.
