It features a 0.381-inch tap shank diameter and a 0.286-inch tap square size, placing it in the NUMERTAP 770 series of precision tapping holders. The outside shank diameter measures 1.25 inches, and the projection is 6.7 inches. Licensed machinists and CNC setup technicians install this adapter as part of a modular quick-change tooling system, allowing fast tap changeovers without removing the toolholder from the spindle.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for production tapping applications in precision machining environments, including job shops and manufacturing facilities running high-volume or mixed-lot work. The NUMERTAP 770 series is designed for use where consistent tap alignment and depth control are critical. It does not include coolant-through capability, making it best suited for applications where flood or mist coolant is applied externally rather than through the tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuick-change design allows rapid tap swaps without full toolholder removal\u003c\/li\u003e\n\u003cli\u003e0.381-inch tap shank diameter fits standard tapping tool shanks in this size range\u003c\/li\u003e\n\u003cli\u003e0.286-inch tap square size provides 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 stable seating in the toolholder body\u003c\/li\u003e\n\u003cli\u003ePart of the NUMERTAP 770 modular series for consistent system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use within the PARLEC NUMERTAP 770 series quick-change tapping system.

Verify that the tap shank diameter and square size match the adapter specifications before seating the tap. Confirm projection length suits the workpiece setup and that no interference exists with fixtures or the machine table.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Square Size\u003c\/strong\u003e: 0.286 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: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: NUMERTAP 770\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7716-6-037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52030635901234,"sku":"7716-6-037","price":261.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1a425c4b4d323a9bce3fc3726743567_821b3625-73ff-4540-93d3-7012693251bc.jpg?v=1790019519","url":"https:\/\/voomisupply.com\/products\/parlec-7716-6-037-tapping-adapter-numertap-770","provider":"Voomi Supply","version":"1.0","type":"link"}
