Built from solid carbide grade K20C, it delivers consistent thread geometry in demanding machining environments. The tool features 6 flutes and an uncoated bright finish, with a 0.62 inch cutting diameter and a 1.5 inch length of cut. At 3.62 inches overall length with a 5\/8 inch shank diameter, it mounts securely in standard toolholders. Machinists and CNC operators use this mill to produce accurate internal threads in a single helical pass, making it a reliable choice for production and job-shop threading operations.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machining internal 1-8 UNC threads in workpieces where tapping is impractical or where thread quality control is critical. It is appropriate for use in CNC machining centers capable of helical interpolation. The solid carbide K20C construction makes it well suited for threading ferrous and non-ferrous materials where rigidity and wear resistance are required. Minimum nominal bore diameter for this tool is 1 inch. Coolant-through capability is not available on this tool, so flood or mist external coolant is the recommended approach for chip evacuation during threading cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC internal thread specification with 8 teeth per inch\u003c\/li\u003e\n  \u003cli\u003e6-flute straight flute geometry for stable cutting action\u003c\/li\u003e\n  \u003cli\u003eSolid carbide K20C material for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch shank diameter for secure toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through channels — compatible with external flood or mist coolant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with helical interpolation capability and standard toolholders accepting a 5\/8 inch straight shank.

Ensure the spindle and toolholder are fully powered down and the machine is in a safe state before loading the tool. Confirm runout and shank seating in the toolholder before initiating a threading cycle. Follow the machine tool manufacturer programming guidelines for helical interpolation and feed rate settings appropriate 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: 1-8\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: 8\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: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 1 inch\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: K20C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716035019058,"sku":"70129","price":1137.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_5c3288a5-543a-4432-b34f-3a721a89827a.jpg?v=1788521349","url":"https:\/\/voomisupply.com\/products\/value-collection-70129-thread-mill-1-8-unc-6-flutes-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
