HSS Second (Intermediate) Short Hand Tap 1/4" UNF

The SOMTA 5510642 - 1/4" HSS Second (Intermediate) Short Hand Tap is a precision tool designed for general-purpose hand tapping in both workshop and maintenance environments. Compliant with ISO 529 standards and manufactured from high-speed steel (HSS), this tap produces Unified Fine (UNF) threads with a 60° flank angle and ISO 2 / 2B tolerance. The straight flute design supports reliable chip removal, and the right-hand cutting action ensures compatibility with standard tapping procedures. As the second tap in a 3-piece sequence, it is intended for continued thread forming after the taper stage. This listing is for one individual second (intermediate) tap only.
