It accepts a tap shank diameter of 0.318 inches and a tap square size of 0.238 inches, providing a secure and repeatable connection between the tapping head and the cutting tool. With a 6.7-inch projection and a 1.25-inch outside shank diameter, this adapter suits a range of machine spindle setups. It is installed by machinists and tooling technicians working in metal fabrication, job shops, and production facilities requiring consistent thread quality.\u003c\/p\u003e\n\u003cp\u003eThe 7716-6-031 is suited for use in vertical and horizontal machining centers where quick-change tooling systems reduce setup time between operations. The NUMERTAP 770 Series is designed for synchronous and semi-synchronous tapping applications. This adapter does not include coolant-through capability, making it appropriate for operations where flood or external coolant delivery is sufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-change interface for fast tool changeover in production environments\u003c\/li\u003e\n  \u003cli\u003eTap shank diameter of 0.318 inches for precise tool seating\u003c\/li\u003e\n  \u003cli\u003eTap square size of 0.238 inches ensures positive drive engagement\u003c\/li\u003e\n  \u003cli\u003e6.7-inch projection accommodates deep-reach tapping setups\u003c\/li\u003e\n  \u003cli\u003e1.25-inch outside shank diameter for rigid spindle connection\u003c\/li\u003e\n  \u003cli\u003ePart of the NUMERTAP 770 Series for system-level compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use within the PARLEC NUMERTAP 770 Series quick-change tapping system.
