The cutting diameter is 0.3 inches, supported by a 0.375-inch shank and a neck diameter of 0.219 inches. The AlTiN coating extends tool life in ferrous and high-temperature alloy materials by reducing heat absorption at the cutting edge. With 4 flutes and a 2.5-inch overall length, this tool is suited for CNC machining centers running helical interpolation thread milling cycles.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for use on CNC machining centers where a single tool must produce multiple thread pitches in the 3\/8 thread size range. It handles both internal and external thread forms, making it practical for shops that need versatility without a dedicated tap for each pitch. The 1.25-inch neck length provides clearance for threading into blind holes and standard-depth bores. Typical applications include precision component machining in aerospace, medical, and general manufacturing environments where thread quality and tool life are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads from 3\/8-16 to 3\/8-40 with one tool\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e4-flute geometry for efficient chip evacuation during helical interpolation\u003c\/li\u003e\n\u003cli\u003e0.219-inch neck diameter provides clearance in blind hole applications\u003c\/li\u003e\n\u003cli\u003e1.25-inch neck length accommodates standard bore depths in the 3\/8 thread range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a single profile thread mill for CNC machining centers capable of helical interpolation; compatible with standard 3\/8-inch collet or end mill toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified CNC machinist familiar with thread milling cycles and helical interpolation programming. Secure the shank fully in a collet or end mill holder, ensuring runout is minimized before cutting. Thread milling requires a CNC control capable of executing G02 or G03 helical arc moves with proper pitch programming. Do not use this tool in manual machines or as a rigid-tap replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 3\/8-16 to 3\/8-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 16 to 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3 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\u003eNeck Diameter\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 54260-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730999673138,"sku":"54260-C3","price":214.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cde1d1fec4922d086c1506b93d42cb1_24efde48-6900-4586-b7cf-b364c8f65e73.jpg?v=1788725651","url":"https:\/\/voomisupply.com\/products\/harvey-tool-54260-c3-thread-mill-3-8-16-to-3-8-40-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
