Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers wear resistance and thermal stability in demanding cutting conditions. It runs 3 right-hand flutes and targets a 1\/2-13 thread size with a cutting diameter of 0.3700 inches and a length of cut of 1.2000 inches. The long-reach design suits deep-thread applications where standard-length tools cannot reach the full thread depth. Machinists in production shops and tool rooms are the primary users.\u003c\/p\u003e\u003cp\u003eThis thread mill is built for internal UNC thread milling operations on CNC machining centers. The 3\/8-inch shank diameter and 3.5000-inch overall length support long-reach setups in ferrous and non-ferrous workpiece materials. The AlTiN+ coating extends tool life in harder alloys and elevated cutting temperatures. No coolant-through capability is present, so external coolant or air blast is the standard approach for chip evacuation. Typical applications include threading bored holes in aluminum, steel, and stainless workpieces where a single thread mill replaces multiple taps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides oxidation resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eLong-reach thread mill type suits deep-hole internal threading\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes for smooth chip flow in internal threading operations\u003c\/li\u003e\n\u003cli\u003eCuts 1\/2-13 UNC internal threads at 13 TPI with a 0.3700-inch cutting diameter\u003c\/li\u003e\n\u003cli\u003e1.2000-inch length of cut accommodates a range of thread depths in a single pass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation for internal UNC thread milling with a 3\/8-inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control with helical interpolation capability  -  confirm machine compatibility before setup. Secure the 3\/8-inch shank in a properly sized collet or milling chuck and verify runout before cutting. Power down the spindle and secure the workpiece fully before making any tool changes or adjustments. Since this tool has no coolant-through feature, direct external coolant or compressed air at the cutting zone to clear chips and manage heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 13 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2000 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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 inches\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\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: 3.2 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: TMLR370-13ELA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52106122068274,"sku":"TMLR370-13ELA","price":175.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b88fa4f04f667ce6dc1e650efb598e80_995fca83-15ea-44b1-8535-4859edda218f.jpg?v=1790073226","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr370-13ela-thread-mill-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
