Built from submicron solid carbide, it delivers the rigidity and edge retention needed for precision threading in demanding production environments. With a 0.372-inch cutting diameter, a 0.375-inch shank diameter, and a 3-inch overall length, this tool is sized for CNC machining centers running thread milling cycles. The bright, uncoated finish makes it well suited for threading operations where coating buildup or adhesion is a concern. Four flutes provide efficient chip evacuation across the full thread pitch range.\u003c\/p\u003e\n\u003cp\u003eThe SPTM372 handles both internal and external threading in a single tool, reducing the need for multiple taps or dies in a job setup. It is appropriate for threading 1\/2-inch fastener profiles in materials where solid carbide performs reliably, including steels, aluminum alloys, and similar workpiece materials. The 0.85-inch length of cut and 0.24-inch neck diameter allow it to reach thread depths without excessive overhang in standard CNC setups. This tool is a practical choice for machine shops, tool and die operations, and production facilities running thread milling on multi-axis or standard 3-axis CNC mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts internal and external threads from 12 to 32 TPI in a single tool\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.372-inch cutting diameter with 0.24-inch neck diameter for clearance in tight bores\u003c\/li\u003e\n  \u003cli\u003e0.85-inch length of cut accommodates standard thread depth requirements\u003c\/li\u003e\n  \u003cli\u003eFour flutes for efficient chip evacuation during thread milling cycles\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for applications where coatings are undesirable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of thread milling cycles, compatible with 1\/2-inch thread profiles ranging from 12 to 32 TPI on both internal and external applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified CNC machinist or tooling specialist. Secure the 0.375-inch shank in a properly sized collet or end mill holder and verify runout before use, as excessive runout will damage thread form accuracy. Confirm that the CNC control is programmed for a helical thread milling interpolation cycle appropriate for the target thread size and pitch. Do not use this tool in manual milling machines or hand-held drilling equipment.\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\/2-12 to 1\/2-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (Min)\u003c\/strong\u003e: 12 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (Max)\u003c\/strong\u003e: 32 TPI\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: 0.372 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.24 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\u003eLength of Cut\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: SPTM372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52059075805490,"sku":"SPTM372","price":92.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9a1d7e0c54266feb615ca17e9912783.jpg?v=1790040113","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm372-thread-mill-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
