Built from powdered metal and finished with a TiCN coating, this tool delivers consistent thread form and extended tool life in ferrous and non-ferrous materials. It runs on a 1\/2 inch shank and features 6 flutes for improved chip evacuation and finish quality. With a 0.48 inch cutting diameter and a 1.12 inch length of cut, it suits a broad range of thread-milling operations on CNC machining centers. Machinists and toolroom technicians select this tool when thread quality and repeatability are the priority.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for production and job-shop environments where a single tool must handle both external and internal 5\/8-20 UN thread forms. The straight flute geometry keeps cutting forces predictable and works well in applications where tool deflection must be minimized. At 4 inches overall length with a 1\/2 inch shank, it fits standard ER and side-lock toolholders commonly found on 3-axis and 4-axis machining centers. It is a practical choice for threading bores and bosses in aluminum, steel, and stainless applications where tap breakage is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-20 UN thread form  -  cuts both external and internal threads with one tool\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved wear resistance and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003ePowdered metal substrate provides consistent hardness and toughness\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes for stable cutting action and efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003e0.48 inch cutting diameter with 1.12 inch length of cut\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  suitable for flood or mist coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation, with 1\/2 inch straight shank compatible with standard ER collet chucks and side-lock toolholders.

Secure the shank fully in the toolholder to the recommended gauge line depth and verify runout before cutting. Use appropriate feeds, speeds, and coolant for the workpiece material; do not exceed the tool rated depth of cut per pass. Handle carbide and powdered metal tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External and Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.48 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: 1.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\u003c\/strong\u003e: No\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: 0.24 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM480-20N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52103057047858,"sku":"TM480-20N","price":234.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9f6865fd33940c677873dd3fb0647f_536020b2-ad63-443d-ac31-8815388fda11.jpg?v=1790070952","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm480-20n-thread-mill-5-8-20-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
