Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for threading operations in ferrous and non-ferrous materials. The tool features a TiAlN coating that improves heat resistance and extends tool life in demanding cutting conditions. With 4 flutes and a cutting diameter of 0.3050 inches, it produces clean, accurate threads in a single helical pass. The 5\/16-inch shank diameter is compatible with standard CNC toolholders. This tool is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for internal threading operations on CNC machining centers where a single tool must produce a complete 7\/16-14 UNC thread form. The 0.8750-inch length of cut accommodates through-holes and blind holes within that depth range. The minimum nominal diameter this tool addresses is 0.4375 inches. It is commonly used in aerospace, automotive, and general manufacturing applications where thread milling is preferred over tapping for improved accuracy, tool life management, or difficult-to-machine materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4 helical flutes for smooth cutting action and chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.3050-inch cutting diameter sized for 7\/16-14 UNC internal threads\u003c\/li\u003e\n\u003cli\u003e0.8750-inch length of cut for through-holes and blind holes up to that depth\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard CNC collet and toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation; produces 7\/16-14 UNC internal threads with a minimum nominal diameter of 0.4375 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills require a CNC control capable of helical interpolation — confirm G-code support before programming the toolpath. Secure the shank in a precision collet or shrink-fit holder to minimize runout, which directly affects thread accuracy. Verify spindle speed and feed rate against the carbide grade and workpiece material before starting the cut. Do not use this tool in manual milling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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: 0.4 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: 930-43714\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746402795826,"sku":"930-43714","price":314.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6645375ee93aecb920533c50a2349d6f.jpg?v=1788869612","url":"https:\/\/voomisupply.com\/products\/accupro-930-43714-thread-mill-7-16-14-unc-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
