Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers consistent thread geometry and extended tool life in demanding CNC milling applications. It features a 0.2850-inch cutting diameter, a 1.0000-inch length of cut, and a long-reach design with a 3\/8-inch shank and 3.5000-inch overall length. It is installed by machinists and CNC programmers working in precision thread milling operations where tap breakage risk must be eliminated.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for internal 3\/8-16 UNC thread applications in production and job shop environments. The long-reach configuration allows access to threads in deeper bores or workpieces with obstructions around the entry point. The right-hand flute direction and three-flute geometry support balanced cutting forces and smooth chip evacuation. It performs in ferrous and non-ferrous materials where AlTiN+ coating provides thermal resistance and wear protection during dry or minimal-lubrication cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal 3\/8-16 UNC threads at 16 teeth per inch\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eLong-reach design with 3.5000-inch overall length for deep-bore access\u003c\/li\u003e\n\u003cli\u003eThree right-hand helical flutes for balanced cutting and chip flow\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement  -  suitable for external coolant or dry cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for internal 3\/8-16 UNC thread milling applications with a 3\/8-inch tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills of this type are installed by CNC machinists using standard ER or precision collet holders matched to the 3\/8-inch shank diameter. The machine control must support helical interpolation to execute proper thread milling cycles. Verify spindle RPM and feed rate against the tool manufacturer recommendations for the workpiece material before running. Inspect the collet and holder for runout prior to use, as excessive runout reduces thread accuracy and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2850 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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: TMLR285-16ELA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51998254596402,"sku":"TMLR285-16ELA","price":177.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b88fa4f04f667ce6dc1e650efb598e80_88dda0db-b845-4733-b6db-ba550c0485fe.jpg?v=1789994752","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr285-16ela-thread-mill-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
