It features a 4.5 mm tap shank diameter and a 3.4 mm tap square size, providing a secure, repeatable connection between the tap and the machine spindle. With an overall length of 26.5 mm and a flange diameter of 22 mm, this adapter is built to the DIN 371 standard. Machinists and tool-and-die technicians use this adapter in CNC machining centers, drill presses, and tapping stations where fast, accurate tool changes are required. It is sold as a single unit.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for light-duty tapping applications using M4 thread-forming or thread-cutting taps. The quick-change design allows the tap to be swapped out without removing the holder from the machine, reducing setup time in production and job-shop environments. A projection of 0.2756 inches (7 mm) and a tap depth capacity of 0.5906 inches (15 mm) make it appropriate for standard M4 threading operations in metal, plastic, or composite workpieces. It does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuick-change design for fast tap installation and removal without removing the holder\u003c\/li\u003e\n\u003cli\u003eTap shank diameter of 4.5 mm and tap square size of 3.4 mm for secure M4 tap retention\u003c\/li\u003e\n\u003cli\u003eBuilt to DIN 371 standard for consistent dimensional compliance\u003c\/li\u003e\n\u003cli\u003eProjection of 0.2756 inches (7 mm) and tap depth of 0.5906 inches (15 mm)\u003c\/li\u003e\n\u003cli\u003eOverall length of 26.5 mm with a 22 mm flange diameter\u003c\/li\u003e\n\u003cli\u003eOutside shank diameter of 13 mm for use with Series WE 0 quick-change holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series WE 0 quick-change tap holders accepting an adapter size 0 interface and M4 tap shanks conforming to DIN 371 dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or tooling technicians familiar with quick-change tapping systems. Ensure the machine spindle is fully stopped and the holder is stationary before inserting or removing the adapter. Verify that the tap shank and square dimensions match the adapter specifications before seating the tap. Follow the machine manufacturer guidelines for torque limits and tap alignment to avoid damage to the adapter or workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdapter Size\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 4.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Square Size\u003c\/strong\u003e: 3.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.2756 inches (7 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Depth\u003c\/strong\u003e: 0.5906 inches (15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 26.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Shank Diameter\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WE 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Standard\u003c\/strong\u003e: DIN 371\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.088 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QA-0 M4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754740678962,"sku":"QA-0 M4","price":40.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/472798cdf86b1dd53bd127efc3da0248.jpg?v=1788948270","url":"https:\/\/voomisupply.com\/products\/accupro-qa-0-m4-tapping-adapter-m4-tap-size-we-0","provider":"Voomi Supply","version":"1.0","type":"link"}
