Built from micrograin solid carbide and coated with TiAlN, this tool delivers thermal and wear resistance required for high-speed threading in ferrous and hardened materials. With 4 flutes, a 0.495 inch cutting diameter, and a 1.25 inch length of cut, it produces clean, accurate internal threads in a single helical interpolation pass. The 1\/2 inch shank diameter fits standard milling chucks and collet holders. It is installed and operated by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machining internal 3\/4-12 UNC threads in materials where tap breakage is a risk or where a single tool must thread a range of hole sizes. Typical applications include aerospace, die and mold, and general precision machining on vertical or horizontal CNC machining centers. The helical flute geometry promotes chip evacuation during interpolation, making it effective in blind and through-hole configurations. Coolant-through is not supported on this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides heat resistance and reduced friction at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e4-flute helical geometry promotes efficient chip evacuation in internal threading\u003c\/li\u003e\n  \u003cli\u003e0.495 inch cutting diameter with 1.25 inch length of cut for threading at depth\u003c\/li\u003e\n  \u003cli\u003e12 TPI matches standard 3\/4-12 thread form specifications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter for compatibility with standard milling tool 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 to produce internal 3\/4-12 thread forms in ferrous, non-ferrous, and hardened workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC programmers familiar with thread milling cycles. Secure the shank in a balanced collet or milling chuck with adequate projection for the application before running. Program the tool for helical interpolation using the correct thread pitch and direction for the intended thread form. Verify spindle speed, feed rate, and depth of cut against the toolmaker recommendations for the workpiece material before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-12\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: 12 TPI\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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.75 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: Micrograin\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: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 930-75012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752179138866,"sku":"930-75012","price":356.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a52fb8180dd0edb529401b015048b8a5.jpg?v=1788926376","url":"https:\/\/voomisupply.com\/products\/accupro-930-75012-thread-mill-3-4-12-internal-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
