With 4 flutes, a 0.345-inch cutting diameter, and 18 teeth per inch, it delivers clean thread forms in ferrous and non-ferrous materials where tap breakage is a concern or blind-hole access requires a more controlled approach. The bright finish keeps the tool free of additional coatings for applications where dimensional tolerance is tight. Machinists and tool-and-die professionals use this mill in CNC machining centers equipped with three-axis helical interpolation capability.\u003c\/p\u003e\n\u003cp\u003eThis tool is suited for internal threading operations in production and job-shop environments where 7\/16-18 UNS thread profiles are required. The 3\/8-inch shank diameter fits standard ER and end mill collet systems, making it compatible with a wide range of machining center spindles. The 0.8-inch length of cut accommodates a range of thread depths without excessive overhang. No coolant-through capability is featured, so flood or mist coolant delivery at the spindle exterior is the standard approach for chip evacuation and heat management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 7\/16-18 UNS internal threads via helical interpolation on three-axis CNC machining centers\u003c\/li\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes with 18 teeth per inch for consistent thread form engagement\u003c\/li\u003e\n  \u003cli\u003e0.345-inch cutting diameter with 0.8-inch length of cut for versatile thread depth range\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard collet toolholders\u003c\/li\u003e\n  \u003cli\u003eBright finish with no additional coating for close dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of three-axis helical interpolation for cutting 7\/16-18 UNS internal threads.

Secure the shank fully within the collet to the recommended grip depth before tightening. Power down the spindle and verify zero spindle speed before tool changes. Do not use this tool on manual mills or in applications requiring straight-plunge threading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.345 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 7\/16 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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM 345-18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52099048505650,"sku":"TM 345-18","price":237.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44baf9865d2a78a37e4db56f69138c1a.jpg?v=1790068004","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm-345-18-thread-mill-7-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
