Built from submicron-grade solid carbide and finished with an AlTiN+ coating, it delivers the hardness and heat resistance required for threading operations in ferrous and non-ferrous materials. The 4-flute geometry produces clean thread forms in a single helical pass. With a 0.24-inch cutting diameter, a 1\/4-inch shank, and an overall length of 2.5 inches, this tool is sized for CNC machining centers where precision and tool longevity are the priority.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for job shops, production machining, and maintenance environments where a single tool must cover a broad TPI range on one shank size. It handles both blind and through-hole applications on a CNC machining center using helical interpolation. The 5\/16-16 to 5\/16-48 thread range makes it a practical choice when cutting fine and coarse threads in the same workpiece without a tool change for thread size. It is installed and run by machinists and CNC programmers working to print tolerances on threaded features in steel, stainless, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle profile design cuts internal and external threads from 16 to 48 TPI with one tool\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides thermal protection and extended tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration for efficient chip evacuation and thread finish quality\u003c\/li\u003e\n  \u003cli\u003e0.153-inch neck diameter allows reach into recessed or counterbored features\u003c\/li\u003e\n  \u003cli\u003e0.8-inch neck length and 0.8-inch length of cut support deep-thread applications within the tool reach envelope\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, with a standard 1\/4-inch straight shank compatible with ER collet chucks and other 1\/4-inch toolholding systems.

Secure the shank in a balanced, concentric toolholder such as an ER collet chuck and verify runout before running. Do not use in manual or non-interpolating setups. Follow the tooling manufacturer and machine builder guidelines for spindle speed, feed rate, and depth of cut for solid carbide thread mills in the work material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 5\/16-16 to 5\/16-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI) Range\u003c\/strong\u003e: 16 to 48 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: 0.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.153 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8 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: 0.06 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: SPTM240LA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51976778023218,"sku":"SPTM240LA","price":85.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/651cf896616581cb60a3e70b5025685c.jpg?v=1789979056","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm240la-thread-mill-5-16-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
