HSS Second (Intermediate) Short Hand Tap 3/8" UNF
The SOMTA 5510952 - 3/8" HSS Second (Intermediate) Short Hand Tap is a high-quality threading tool engineered for general-purpose hand tapping applications. Made from high-speed steel (HSS) and conforming to ISO 529 standards, this tap produces accurate Unified Fine (UNF) threads with a 60° flank angle. Its straight flute design supports effective chip removal, and the right-hand cutting direction ensures compatibility with conventional manual tapping tools. Intended as the second tap in a standard 3-piece sequence, it is ideal for refining threads after the taper tap stage. This listing is for one individual second (intermediate) tap only.
