It produces 1\/2-13 threads with a cutting diameter of 0.35 inches and a length of cut of 0.875 inches. The four right-hand helical flutes and TiAlN coating work together to reduce heat buildup and extend tool life in demanding milling environments. With a 3\/8-inch shank diameter and an overall length of 3.5 inches, this tool mounts securely in standard milling chucks and collet holders. It is intended for use by machinists and CNC operators working with precision thread requirements in production or job shop settings.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for CNC machining centers performing internal thread milling operations on ferrous and non-ferrous materials. The helical flute geometry allows for smooth chip evacuation during the threading pass. At 13 TPI and a minimum nominal diameter of 0.5 inches, it is a direct fit for standard 1\/2-13 UNC internal thread applications. No coolant-through capability is present, so external coolant or air blast is the appropriate delivery method for chip clearing and thermal management during use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in thread milling operations\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e4 right-hand helical flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCuts 1\/2-13 UNC internal threads with a 0.35-inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003e0.875-inch length of cut accommodates standard thread depth requirements\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits common collet and milling chuck toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation, used for producing 1\/2-13 UNC internal threads.

Ensure the spindle and toolholder are clean and within tolerance before seating the shank. Since this tool has no coolant-through capability, confirm that external coolant or air blast is directed at the cutting zone during operation. Follow the machine manufacturer and tooling guidelines for helical interpolation feed rates and stepover values specific to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 0.35 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\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 0.2 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: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM50013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51728237494578,"sku":"TM50013","price":240.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06af72fe67bf7b0168dffdbf4deccec7.jpg?v=1788690000","url":"https:\/\/voomisupply.com\/products\/allied-tm50013-thread-mill-1-2-13-internal-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
