With 4 right-hand flutes and a TiAlN coating, it handles the thermal and abrasive demands of production threading in ferrous and non-ferrous materials. The cutting diameter is 0.495 inches, the length of cut is 1.25 inches, and the overall length is 3.5 inches. The 1\/2-inch shank diameter fits standard toolholders used on CNC machining centers. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for CNC milling machines equipped with helical interpolation capability. It handles both internal bores and external profiles in a single tool, making it practical for shops running mixed threading work. The UN thread standard and 12 TPI specification make it applicable to general industrial fastener and fitting thread profiles in the 3\/4-inch nominal diameter range. No coolant-through capability is present, so flood or mist coolant delivery at the spindle is the recommended approach for chip evacuation and thermal management.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 3\/4-12 UN threads in both internal and external configurations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life at higher surface speeds\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for efficient chip flow during helical interpolation\u003c\/li\u003e\n\u003cli\u003e0.495-inch cutting diameter with 1.25-inch length of cut for through and blind hole applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter fits standard ER and shrink-fit toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation for 3\/4-12 UN internal and external thread milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control with helical interpolation and a correctly programmed toolpath for the target thread pitch and hand. Confirm shank seating depth and runout in the toolholder before cutting — excessive runout degrades thread quality and tool life. Power down and lock out the spindle before tool changes. Follow the machine tool manufacturer and tooling manufacturer feed and speed recommendations for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-12\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: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\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\u003eCutting Diameter\u003c\/strong\u003e: 0.495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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\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: 0.31 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: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM75012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51735298310450,"sku":"TM75012","price":404.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29eb04c3163f743508098fa50791151d.jpg?v=1788771577","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm75012-thread-mill-3-4-12-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
