It accepts a tap shank diameter of 0.168 inches and a tap square size of 0.131 inches, corresponding to a Size 1 tap adapter configuration. The adapter features through-coolant capability, allowing coolant to flow directly to the tap for improved chip evacuation and tool life during production tapping. It is a precision tooling component installed by machinists and tool room technicians on CNC machining centers and tapping machines.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for light-duty tapping applications where Size 1 tap holders are specified. The through-coolant design makes it appropriate for applications requiring consistent coolant delivery at the cutting zone, particularly in production environments where tap life and cycle times are critical. The quick-change feature allows rapid tap swaps without removing the holder from the spindle, reducing changeover time on the machine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 1 tap adapter with 0.168-inch tap shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap square size of 0.131 inches for positive drive engagement\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for direct coolant delivery to the cutting tool\u003c\/li\u003e\n  \u003cli\u003eQuick-change compatible for fast tap exchanges at the spindle\u003c\/li\u003e\n  \u003cli\u003eProjection of 0.28 inches and tap depth of 0.92 inches\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 1.18 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with quick-change tapping tooling systems that accept Size 1 tap adapters with a 0.168-inch shank diameter and 0.131-inch tap square.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or tooling technician. Ensure the spindle and tooling system are fully powered down and the machine is in a safe state before changing adapters. Confirm the tap shank diameter and square size match this adapter before seating the tap to avoid damage to the drive mechanism. Verify coolant line connections are secure if through-coolant is active in the machine setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Adapter Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Square Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Depth\u003c\/strong\u003e: 0.92 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 1.18 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: Yes\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: COLLIS TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 78912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67913088729394,"sku":"78912","price":72.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b07b1f3fed8c0dcfd27afc8e1c27c70.jpg?v=1791242434","url":"https:\/\/voomisupply.com\/products\/collis-tool-78912-tapping-adapter-size-1","provider":"Voomi Supply","version":"1.0","type":"link"}
