HSS NPS 3/8″ Bottom Tap – Somta Series 581
The SOMTA 5810953 – HSS NPS 3/8″ Bottom Tap is a high-precision tool used for cutting straight (parallel) internal pipe threads according to ANSI NPS standards. Built from durable High-Speed Steel (HSS), this tap is ideal for threading the bottom of blind holes where a tight fit is required. The bottoming chamfer design engages only 1–2 threads, allowing full thread cutting very close to the bottom of the hole—perfect for electrical fittings, conduit systems, or low-pressure mechanical applications.
