HSS Second (Intermediate) Short Hand Tap No.10 UNF
The SOMTA 5510482 – No.10 HSS Second (Intermediate) Short Hand Tap is a precision-engineered tool built for general-purpose hand tapping. Crafted from high-speed steel (HSS) and manufactured to ISO 529 standards, this tap produces Unified Fine (UNF) threads with a 60° flank angle and ISO 2 / 2B tolerance. Its straight flute design ensures effective chip removal, while the right-hand cutting action enables smooth operation in both through-hole and blind-hole applications. Designed as the second tap in a 3-piece set, it is used to further develop threads after the taper tap stage. This listing is for one individual second (intermediate) tap only.
