Built from solid carbide in material grade MT7 and finished with a TiAlN coating, this tool delivers thermal resistance and extended tool life in demanding machining environments. It runs 3 right-hand flutes at 13 teeth per inch, with a cutting diameter of 0.362 inches and a length of cut of 0.89 inches. Coolant-through construction supports chip evacuation and heat management at the cutting zone. Machinists and CNC programmers working in production and job-shop environments rely on thread mills like this one when threading blind holes or exotic materials where tap breakage is a concern.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machining centers performing internal thread milling operations in ferrous and non-ferrous materials. The 3\/8-inch shank fits standard collet chucks and toolholders common in vertical and horizontal machining centers. With a 3.00-inch overall length and 2.11-inch shank length, the tool provides reach for moderate-depth applications without sacrificing rigidity. It is appropriate for shops producing threaded features in aluminum, steel, stainless, and similar materials where the 1\/2-13 UNC thread form is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade MT7 for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life and supports dry or near-dry cutting applications\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes for efficient chip flow during thread interpolation\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and thermal control at the cut\u003c\/li\u003e\n  \u003cli\u003eCuts 1\/2-13 UNC internal threads with a 0.362-inch cutting diameter and 0.89-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard collet and milling toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for internal 1\/2-13 UNC thread milling operations on CNC machining centers equipped with helical interpolation capability and toolholders accepting a 3\/8-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread mills are installed and operated by qualified CNC machinists familiar with helical interpolation programming. Secure the shank in a properly sized collet or end mill holder and verify runout before cutting. Program the toolpath using the correct thread mill interpolation cycle for the 1\/2-13 UNC pitch and confirm spindle direction matches the right-hand flute geometry. Always verify workpiece fixturing rigidity and coolant delivery before initiating the threading pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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\u003eTeeth Per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.362 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.89 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.00 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: MT7\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B0375C0813UN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52015492366642,"sku":"B0375C0813UN","price":370.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cda2bf9541b52c4e15206084b274f499.jpg?v=1790007857","url":"https:\/\/voomisupply.com\/products\/carmex-b0375c0813un-thread-mill-1-2-13-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
