Built from submicron-grade solid carbide and finished with an AlTiN Plus coating, this tool delivers consistent thread geometry and extended tool life in demanding machining environments. The 3-flute design balances chip evacuation with cutting stability, making it a reliable choice for machinists working with small-diameter threaded features in precision components.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for use in CNC machining centers where a single tool must produce a range of thread sizes within the #8 thread family. It handles both internal bores and external thread forms, reducing tool changeovers in production runs. Typical applications include aerospace, medical device, and general precision machining where accurate thread profiles and minimal tool deflection are required in small-format workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCovers #8-32 to #8-56 thread range in a single tool, eliminating the need for multiple taps or dies\u003c\/li\u003e\n  \u003cli\u003eCuts both internal and external thread forms\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN Plus coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry promotes efficient chip removal in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.07 inches allows reach into recessed or deep features\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; compatible with standard 3\/16-inch diameter tool holders or collet chucks.

Secure the shank in a precision collet or end mill holder with adequate clamping depth to minimize runout. Always verify programmed thread pitch and helix direction match the intended thread specification before cutting. Inspect the tool for chipping or coating wear between operations, especially when working with hardened materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: #8-32 to #8-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 32 to 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: SPTM120LA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52113412325682,"sku":"SPTM120LA","price":78.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71c3963a174c27cfbafc475442e87629.jpg?v=1790078356","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm120la-thread-mill-8-32-to-8-56","provider":"Voomi Supply","version":"1.0","type":"link"}
