Built from submicron-grade solid carbide with a bright\/uncoated finish, this tool delivers consistent thread geometry across a broad TPI range with a single tool setup. The 6-flute configuration supports efficient chip evacuation and smooth cutting action. With a 0.745-inch cutting diameter, 0.750-inch shank, and 5-inch overall length, it fits standard CNC milling setups used in machining and toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machine shops, toolrooms, and manufacturing facilities requiring precise thread milling on larger-diameter fastener features. It handles both internal bores and external boss threads, making it a versatile option for fixtures, adapters, flanges, and similar components. The single profile design allows thread pitch adjustment through programmed helical interpolation, giving operators flexibility across the supported TPI range without changing tools. Licensed machinists and CNC operators working in job shop or production environments are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts internal and external threads from 4 to 8 TPI in the 1-1\/4 thread size range\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e6-flute design promotes efficient chip removal during thread milling cycles\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e0.400-inch neck diameter with 1.500-inch neck length provides clearance in deeper bores\u003c\/li\u003e\n  \u003cli\u003eSingle profile geometry allows pitch flexibility via CNC helical interpolation\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.

Secure the 3\/4-inch shank in a properly sized, clean collet or end mill holder and confirm runout before production cutting. Power down and lock out the spindle before any tool change or holder adjustment. Thread milling programs must use helical interpolation; verify the CNC program pitch and direction match the intended thread specification before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 1-1\/4-4 to 1-1\/4-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 4 to 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.745 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SPTM745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51960424333618,"sku":"SPTM745","price":230.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e752d09f8f3a31209a115b67bcd052d0.jpg?v=1789946364","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm745-single-profile-thread-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
