Built from submicron-grade solid carbide and finished with an AlTiN+ coating, it delivers consistent thread geometry and extended tool life in demanding machining environments. The 4-flute design handles thread sizes from 1\/4-18 to 1\/4-56 with a cutting diameter of 0.182 inches and an overall length of 2.5 inches. This tool is used by machinists and CNC programmers in job shops, production facilities, and toolrooms requiring precise thread milling in a single pass.\u003c\/p\u003e\u003cp\u003eThe SPTM182MLA is suited for thread milling operations on CNC machining centers where helical interpolation is available. Its compact neck diameter of 0.104 inches and neck length of 0.530 inches provide clearance in tight-bore applications. The tool handles both internal and external thread profiles, making it a versatile option for shops running mixed thread programs without retooling. It is appropriate for use in materials where AlTiN+ coating provides thermal and wear resistance, including hardened steels and high-temperature alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCovers 18 to 56 TPI in a single tool, reducing inventory for fine-pitch thread programs\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute geometry supports efficient chip evacuation during helical interpolation\u003c\/li\u003e\n\u003cli\u003eCuts both internal and external threads without a tool change\u003c\/li\u003e\n\u003cli\u003eReduced neck diameter of 0.104 inches allows access in shallow-bore and close-tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation; accommodates thread sizes from 1\/4-18 to 1\/4-56 in both internal and external configurations with a 1\/4-inch shank for standard collet or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified CNC machinists familiar with thread milling cycles and helical interpolation programming. Confirm spindle and tool holder runout before use, as carbide thread mills are sensitive to setup error. Ensure the machine tool is fully powered down and the spindle is at rest before loading or removing the tool. Follow the tool manufacturer and machine tool builder recommendations for cutting parameters, coolant application, and depth-of-cut limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 1\/4-18 to 1\/4-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum TPI\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TPI\u003c\/strong\u003e: 56\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.182 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\u003eNeck Diameter\u003c\/strong\u003e: 0.104 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.530 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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\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\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: SPTM182MLA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52034284257586,"sku":"SPTM182MLA","price":83.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02dc70b42f5695e7acc3f3c1cb020108.jpg?v=1790022198","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm182mla-thread-mill-18-56-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
