Built with 4 right-hand flutes and a TiAlN coating, it delivers thermal resistance and extended tool life in demanding machining environments. The cutter runs a 0.495-inch cutting diameter with a 1.25-inch length of cut and a 3.5-inch overall length. Shank diameter is 0.5 inches. This tool is intended for use by machinists and CNC operators working in production or job-shop settings where metric thread milling is required in place of traditional tapping.\u003c\/p\u003e\u003cp\u003eThe TM20250 is suited for M20 x 2.50 metric thread applications in both internal and external configurations. Its helical flute geometry supports chip evacuation during threading operations. Minimum nominal diameter for this tool is 0.7874 inches (20.00 mm), making it appropriate for threading bores and external diameters at or above that threshold. Coolant-through capability is not included, so external or flood coolant delivery should be planned at setup. This tool is a fit for ferrous and non-ferrous workpiece materials where TiAlN coating provides a performance advantage at elevated cutting temperatures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts M20 x 2.50 internal and external metric threads in a single tool\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e0.495-inch cutting diameter with 1.25-inch length of cut\u003c\/li\u003e\n\u003cli\u003eNo coolant-through — requires external coolant delivery at the machine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification thread mill for M20 x 2.50 metric thread applications requiring a 0.5-inch shank diameter toolholder and a minimum bore or feature diameter of 0.7874 inches (20.00 mm).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool is performed by a CNC machinist or toolroom technician. Secure the 0.5-inch shank in a compatible collet chuck or end mill holder with appropriate runout tolerance before operation. Program thread milling cycles according to the machine control and verify pitch, direction, and depth parameters against the M20 x 2.50 specification before cutting. Do not use this tool without adequate flood or mist coolant directed at the cutting zone, as coolant-through is not available on this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20 x 2.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 2.50 mm\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\u003eCoating\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: 0.31 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TM20250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51732096057650,"sku":"TM20250","price":407.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/341709a71f91567d358164f4c5c375cb_811e62e8-cfdb-4ff6-b340-4462c5476596.jpg?v=1788739138","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm20250-thread-mill-m20x2-50-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
