RIDGID® E-5120 2″ NPT Hand Pipe Tap, Catalog 35855 — carbon steel, right-hand, 11-1/2 TPI, marked “2-13/64” drill size, 3/4″ per foot taper for restricted-area threading and cleanup

RIDGID® E-5120 2″ NPT Hand Pipe Tap, Catalog 35855 — carbon steel, right-hand, 11-1/2 TPI, marked “2-13/64” drill size, 3/4″ per foot taper for restricted-area threading and cleanup Condition: Used — fully functional with normal cosmetic wear from prior use. Hand-use only. No handle, holder, or cutting oil included. Description The RIDGID E-5120 (Cat. No. 35855) is a 2″ NPT hand pipe tap designed for cutting or chasing National Pipe Taper threads where power tapping isn’t practical. Made in the USA from carbon steel, it features a right-hand thread form at 11-1/2 TPI, the standard 3/4″ per foot NPT taper, and clear “2-13/64” pilot drill marking on the shank for quick setup. Its hand-tap geometry and compact shank make it ideal in restricted spaces, repair work, and field service on steel, malleable iron, and rigid plastics (with appropriate technique and lubricant). Designed for hand use only with an appropriate tap wrench. Use quality thread cutting oil, start square to the hole, and back off to break chips. Features 2″ NPT (11-1/2 TPI) right-hand taper thread Carbon steel construction for toughness and resharpenability 3/4″ per foot taper (standard NPT) for proper sealing engagement Marked pilot drill size: 2-13/64″ for through/bore preparation Hand-tap style for manual tapping and thread restoration Restricted-area friendly design for tight access applications Weight: ~3-1/4 lb (approx.)
