The Bordo 3/8" x 24 Left Hand UNF HSS Tap Set is engineered for cutting left-hand Unified National Fine (UNF) internal threads with consistent accuracy in workshop and trade environments. UNF threads are specified by major diameter and threads per inch (TPI) and are commonly used where a fine pitch is preferred for engagement and performance in certain assemblies.
Manufactured from High Speed Steel (HSS) for general-purpose use in medium tensile materials, this set is suitable for hand tapping or general machine use. The tap set format supports staged cutting — including starting in difficult or high precision holes, cutting true to a pre-drilled pilot hole, and finishing with minimal run-out in blind holes.
