Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers consistent thread geometry in demanding machining environments. The 4-flute design provides chip clearance and stability during helical interpolation. With a 0.24-inch cutting diameter, a 0.145-inch neck diameter, and a 2.5-inch overall length, it fits standard CNC machining center setups where tight thread tolerance and tool rigidity are required. Machinists and tooling specialists working in production or job shop environments install and operate this tool.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for external thread milling operations on CNC machining centers using helical interpolation. The 16 TPI single profile geometry makes it appropriate for unified or custom thread forms in that pitch range. Applications include threading in steel, stainless steel, aluminum, and other materials where AlTiN+ coating provides thermal resistance and extended tool life. The 1\/4-inch shank diameter fits standard collet and toolholder systems commonly found in vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle profile design mills external threads at 16 TPI via helical interpolation\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating improves thermal resistance and extends tool life in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e4 flutes for improved chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e0.145-inch neck diameter provides clearance in confined thread entry conditions\u003c\/li\u003e\n\u003cli\u003e0.75-inch neck length supports reach into standard thread depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style single profile thread mill for use in CNC machining centers with helical interpolation capability and standard 1\/4-inch collet or toolholder systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation require a CNC machining center programmed for helical interpolation. Verify toolholder runout before use, as carbide thread mills are sensitive to excessive runout that can cause premature tool failure or off-tolerance threads. Always confirm spindle speed and feed rate settings match the workpiece material and tool manufacturer recommendations before cutting. Handle solid carbide tooling carefully to avoid chipping the flutes or coating during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\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\u003eCutting Diameter\u003c\/strong\u003e: 0.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.145 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.75 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\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: AlTiN+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SPTM240FA-16EXA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971379659058,"sku":"SPTM240FA-16EXA","price":116.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/834a651c4bed4d5f10cf63443f9b2a46.jpg?v=1789956324","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm240fa-16exa-thread-mill-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
