With four right-hand flutes and a TiAlN coating, it handles demanding materials while maintaining edge life in production environments. The cutting diameter is 0.472 inches, the length of cut is 1.22 inches, and the overall length is 3.5 inches. Engineered to Material Grade MT7, this tool delivers consistent thread geometry on CNC machining centers where precision and repeatability are required.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal threading applications in job shops, production machining, and tool rooms working with ferrous and non-ferrous materials. The 1\/2 inch shank diameter fits standard ER and shrink-fit toolholders commonly found on vertical and horizontal machining centers. The helical flute design allows interpolation on three axes, making it effective for through-holes and blind holes where tap breakage is a concern.\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\u003eSolid carbide construction in Material Grade MT7 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e0.472 inch cutting diameter with 1.22 inch length of cut for threading depth flexibility\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  compatible with external coolant or mist applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation; accepts standard 1\/2 inch shank toolholders.

Secure the tool in a balanced, properly torqued toolholder before spindle engagement. Program the correct helical interpolation cycle per the machine control to achieve the specified thread pitch and depth. Verify workpiece fixturing and runout before cutting to avoid thread form errors or tool breakage.\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\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: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.22 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\u003eShank Length\u003c\/strong\u003e: 1.8 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\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\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: 0.23 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: MT0500D1216UN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51994972520754,"sku":"MT0500D1216UN","price":384.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f1cd0b75e26b28b2521ededafadc7e.jpg?v=1789992315","url":"https:\/\/voomisupply.com\/products\/carmex-mt0500d1216un-thread-mill-3-4-16-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
