Built from submicron-grade solid carbide with an AlTiN+ coating, this tool delivers wear resistance and thermal stability suited to production environments. The 4-flute, right-hand helical design with a 0.4950-inch cutting diameter and 1.3380-inch length of cut allows full-thread-depth engagement in a single helical interpolation pass. At 4.0000 inches overall length, this is a long-reach configuration, making it practical for threading deeper bores where standard-reach tools cannot reach the required depth.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal UNF thread generation in ferrous and non-ferrous materials where thread milling is preferred over tapping  -  particularly in interrupted cuts, blind holes, or hard materials where tap breakage risk is a concern. The 0.5000-inch shank diameter allows direct mounting in standard ER collet chucks or shrink-fit holders commonly found on CNC machining centers. It is used by machinists and CNC programmers in job shops, aerospace, automotive, and general precision manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 3\/4-16 UNF internal threads at 16 teeth per inch\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand helical geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLong-reach design at 4.0000 inches OAL for deep-bore thread applications\u003c\/li\u003e\n  \u003cli\u003e0.5000-inch shank fits standard collet chucks and shrink-fit holders\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.

Secure the shank fully in a balanced, high-precision toolholder and confirm runout is within acceptable limits before cutting. Thread mill programs should be generated or verified with CAM software or a dedicated thread milling calculator using the actual cutting diameter. This tool does not support coolant-through delivery  -  apply flood or mist coolant externally at the cutting zone as needed.\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 Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.4950 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.3380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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: 0.42 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMI495-16HA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52001470120242,"sku":"TMI495-16HA","price":282.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/525159b0bd29c3978bf63481d3c63d2d.jpg?v=1789997304","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmi495-16ha-thread-mill-3-4-16","provider":"Voomi Supply","version":"1.0","type":"link"}
