Built within the NUMERTAP 770 Series platform, it accepts a 1\/2-inch pipe tap with a shank diameter of 0.687 inches and a tap square size of 0.515 inches. The outside shank diameter measures 1.25 inches, and the adapter provides a projection of 2.25 inches. Machinists and CNC operators rely on this adapter for consistent tap engagement and repeatable depth control in moderate-to-high-volume tapping cycles.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for shops running NUMERTAP 770 Series quick-change tooling systems on CNC machining centers, tapping machines, and drill presses. It is intended for pipe thread tapping operations where a 1\/2-inch pipe tap must be driven with controlled torque and axial float. The quick-change interface allows fast tap changeovers without removing the holder from the spindle, reducing setup time on multi-tap jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-change interface compatible with NUMERTAP 770 Series holders\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/2-inch pipe taps with 0.687-inch shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap square drive size of 0.515 inches for positive torque engagement\u003c\/li\u003e\n  \u003cli\u003eOutside shank diameter of 1.25 inches for secure holder retention\u003c\/li\u003e\n  \u003cli\u003e2.25-inch projection provides clearance for most standard pipe tapping depths\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  suitable for flood or mist coolant environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the PARLEC NUMERTAP 770 Series quick-change tapping system, accepting 1\/2-inch pipe taps with a 0.687-inch tap shank diameter and a 0.515-inch tap square size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and changeover should be performed by a qualified machinist or tooling technician. Ensure the spindle is at a full stop and machine power is off or in a safe lockout state before changing adapters or taps. Verify tap shank diameter and square size match the adapter specifications before seating the tap. Follow the machine tool manufacturer guidelines for tapping speeds and feeds appropriate to pipe thread geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: NUMERTAP 770\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 1\/2 inch Pipe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Square Size\u003c\/strong\u003e: 0.515 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Shank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick-Change\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7717-050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52038709575986,"sku":"7717-050","price":111.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/083299868414b534d89970aaa8aa80c7.jpg?v=1790025591","url":"https:\/\/voomisupply.com\/products\/parlec-7717-050-tapping-adapter-1-2-inch-pipe","provider":"Voomi Supply","version":"1.0","type":"link"}
