Phantom HSS Hand tap ISO 529 Form C, for Phan-Coil (STI) Metric Coarse

Professional Phantom HSS Tap, ISO 529 Form C, specifically designed for installing Phan-Coil thread inserts. Manufactured from high-quality HSS for reliability. This tap cuts the special oversized thread into which you insert the Phan-Coil insert (for thread repair or reinforcement). A characteristic feature of Form C is the very short initial cut (approx. 1–2 threads). This makes the tap essential for the finishing pass and for tapping blind holes close to the bottom. After installing the insert, the nominal metric internal thread is formed.
