It runs 4 flutes with a 0.49-inch cutting diameter and a 1-inch length of cut, making it suitable for threading operations that require tight tolerances and clean thread form in a single helical pass. The micrograin carbide substrate provides the hardness and wear resistance needed for production environments, while the TiAlN coating extends tool life in ferrous and high-temperature alloy materials. Shank diameter is 0.5 inches. This tool is used by machinists and toolroom technicians on CNC machining centers capable of helical interpolation.\u003c\/p\u003e\n\u003cp\u003eThe C911-75016 is intended for internal UNF thread milling in applications where tapping is impractical or where a single tool must handle multiple thread depths. Typical use cases include threading blind holes, hard materials, and applications requiring left- or right-hand threads from the same tool path. At 16 teeth per inch, this mill matches the 3\/4-16 UNF thread standard precisely. It is well suited for job shops, aerospace component work, and general precision machining where thread quality and tool longevity are critical requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts internal 3\/4-16 UNF threads with 4-flute helical geometry for improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction provides rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life in ferrous and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003e0.49-inch cutting diameter and 1-inch length of cut accommodate standard hole depths for 3\/4-16 thread engagement\u003c\/li\u003e\n  \u003cli\u003e0.5-inch shank diameter fits standard ER and milling collet systems\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; flood or mist coolant applied externally at the spindle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation for internal 3\/4-16 UNF thread milling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a clean, properly sized collet or milling chuck to ensure runout is within acceptable limits before threading operations begin. Confirm the machine control supports helical interpolation and that the programmed thread pitch matches the 16 TPI specification of this tool. Use appropriate speeds and feeds for the workpiece material and apply external flood or mist coolant, as this tool does not include through-coolant capability. Handle carbide tooling with care to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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: 0.32 pounds\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C911-75016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728205676850,"sku":"C911-75016","price":264.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0188e06e1ed3a383015d34d600d1e89b.jpg?v=1788689519","url":"https:\/\/voomisupply.com\/products\/accupro-c911-75016-thread-mill-3-4-16-internal-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
