Phantom HSS Hand tap ISO 529 Form C, Oversized Metric Coarse

Professional Phantom HSS Hand Tap, compliant with ISO 529, Form C, for cutting metric threads with a specific oversize of 0.1 mm or 0.2 mm. Manufactured from high-quality HSS for reliable manual use. This “Over-size” version cuts a larger diameter than the standard (6H) tolerance. This is essential when the thread will undergo post-processing (such as coating) or for repair purposes. A characteristic feature of Form C is the very short initial cut (approx. 1–2 threads), making this tap ideal for the finishing pass and for tapping blind holes close to the bottom.
