Built from IN2005-grade solid carbide and coated with TiAlN for heat and wear resistance, this tool cuts UN-standard threads at 5\/16 inch thread size with 18 teeth per inch. The 3-flute, right-hand helical design provides smooth chip evacuation and accurate thread form. With a long-reach configuration and 0.9100-inch length of cut, it handles threads in deeper bores where standard-length tooling cannot reach. Machinists, tool and die makers, and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for threading operations in ferrous and non-ferrous materials where conventional tapping is not practical or where a single tool must produce multiple thread sizes in the same diameter family. The long-reach geometry makes it appropriate for aerospace, automotive, and general precision machining applications where bore depth demands extended tool projection. It mounts via a straight cylindrical shank and fits standard collet chucks or milling tool holders sized for 0.2500-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide IN2005 grade construction for rigidity and wear life in demanding materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides high-temperature resistance and extends tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand helical geometry supports efficient chip removal and stable cutting forces\u003c\/li\u003e\n\u003cli\u003eLong-reach design with 1.5900-inch shank length enables threading in deep or obstructed bores\u003c\/li\u003e\n\u003cli\u003eUN thread standard compatibility at 18 teeth per inch for 5\/16 inch thread size\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure clamping in collet chucks or shrink-fit holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation, compatible with tool holders accepting a 0.2500-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling with this tool requires a CNC machining center programmed for helical interpolation. Ensure the spindle and tool holder are free of runout before use, as excessive runout degrades thread quality and shortens tool life. Confirm the machine is at a complete stop and spindle power is off before loading or removing the tool from the holder. Coolant-through is not supported on this tool, so external coolant or minimum quantity lubrication should be directed at the cutting zone when required by the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: IN2005\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2360 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.9100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\u003eSeries\u003c\/strong\u003e: MTECS-UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2946129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51963225604402,"sku":"2946129","price":283.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ed7cb1d325adceaebaa91d65874bd8d.jpg?v=1789948250","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-2946129-thread-mill-5-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
