Built for precision threading of 0-80 unified fine threads at 80 TPI, this tool features a 0.044 inch cutting diameter and a 1\/8 inch shank diameter, making it suited for miniature and fine-pitch threading applications. With 2 flutes and a bright uncoated finish, the 41402 delivers clean thread geometry in a compact 1.5 inch overall length package. Licensed machinists and CNC operators rely on this style of thread mill where tapping is impractical due to feature size, blind hole constraints, or material hardness.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is intended for use in CNC machining centers capable of helical interpolation. It is well suited for threading small-diameter holes and external bosses in metals, plastics, and other machinable materials where 0-80 thread forms are specified. The 0.024 inch neck diameter and 0.125 inch neck length allow reach into tight features. Both internal and external thread profiles are achievable with a single tool, reducing tooling inventory for shops that regularly encounter miniature thread specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and tool life in precision threading applications\u003c\/li\u003e\n  \u003cli\u003eSingle profile design cuts 0-80 threads at 80 TPI in one helical interpolation pass\u003c\/li\u003e\n  \u003cli\u003eCuts both internal and external thread forms with one tool\u003c\/li\u003e\n  \u003cli\u003e0.044 inch cutting diameter accommodates miniature thread requirements\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry balances chip evacuation with cutting edge strength at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style single profile thread mill for CNC machining centers that support helical interpolation, suitable for cutting 0-80 unified fine thread forms in internal and external applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation of this thread mill should be performed by qualified CNC machinists familiar with helical interpolation programming. Secure the 1\/8 inch shank in a compatible collet or end mill holder rated for the shank diameter before use. Verify spindle runout is within acceptable limits before cutting, as excessive runout at this tool diameter can cause premature breakage or out-of-tolerance threads. Always confirm the correct helical toolpath direction for internal versus external thread cutting in the CNC program before running the cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 80\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: 0.044 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.024 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739242201394,"sku":"41402","price":144.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec502d8d4b5342249c77fa446c3a5366_f17a4487-efa2-40c2-a004-6868f7831f87.jpg?v=1788811982","url":"https:\/\/voomisupply.com\/products\/harvey-tool-41402-single-profile-thread-mill-0-80-80-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
