Built from submicron-grade solid carbide and coated with AlTiN+ for heat and wear resistance, this tool is engineered for precision threading in CNC machining centers. It features a 0.235-inch cutting diameter, a 0.250-inch shank diameter, and a 2.5-inch overall length. The 4-flute geometry and 0.900-inch length of cut make it well-suited for clean, accurate thread profiles in ferrous and non-ferrous materials. Machinists and CNC operators in metalworking, toolroom, and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used for generating internal threads in CNC milling applications where a single profile tool is preferred for its flexibility across thread depth and starting position. The 0.130-inch neck diameter and 0.900-inch neck length provide clearance for threading operations in blind or through holes requiring a 7\/16-12 thread form. It is suited for production and prototype work in aerospace, automotive, and general machining environments where solid carbide tooling and AlTiN+ coating deliver consistent tool life under high-speed cutting conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle profile design mills 7\/16-12 internal threads at 12 TPI\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating improves performance in high-temperature and abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration for efficient chip evacuation during internal threading\u003c\/li\u003e\n  \u003cli\u003e0.130-inch neck diameter with 0.900-inch neck length provides clearance in confined bore geometries\u003c\/li\u003e\n  \u003cli\u003e0.900-inch length of cut accommodates a range of thread depths within the 7\/16-12 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for single profile thread milling of 7\/16-12 internal threads.

A licensed machinist or qualified CNC operator should verify spindle speed, feed rate, and helical pitch settings against the manufacturer's cutting data before running the tool. Ensure the workpiece is securely fixtured and the tool is seated fully in the holder before initiating the cut. Do not exceed the tool's rated cutting diameter or depth of cut without consulting the manufacturer's application guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 0.235 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.900 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\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SPTM235FA-12LA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52088020894002,"sku":"SPTM235FA-12LA","price":114.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2119b7138acc3829b47b8ec4f900a5b3.jpg?v=1790060727","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm235fa-12la-thread-mill-7-16-12","provider":"Voomi Supply","version":"1.0","type":"link"}
