With 3 flutes and an AlTiN coating, this tool delivers durability and heat resistance in demanding ferrous and hardened material machining environments. The 0.2350-inch cutting diameter and 0.6250-inch length of cut allow precise thread engagement, while the 1\/4-inch shank fits standard collet chucks and tool holders. Machinists and CNC operators in manufacturing, aerospace, and general metalworking shops rely on tools like this for thread milling operations where tap breakage risk or blind-hole constraints make tapping impractical.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for use on CNC machining centers capable of helical interpolation. It handles both internal and external 5\/16-24 thread profiles in a single tool, reducing tooling inventory requirements. The 2.5-inch overall length provides clearance in most standard setups. Applications include precision threading in aluminum, steel, stainless, and other materials where the AlTiN coating provides thermal protection and extended tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 5\/16-24 UNF threads in both internal and external configurations\u003c\/li\u003e\n  \u003cli\u003e3-flute helical design for efficient chip evacuation during thread milling\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e24 teeth per inch with 0.2350-inch cutting diameter for accurate thread form\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suitable for flood or mist coolant delivery at the spindle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers with helical interpolation capability.

Secure the shank fully in a collet or end mill holder before operation and verify runout before cutting. Program the correct helical interpolation path for the target thread pitch and direction. Follow machine tool manufacturer guidelines for feeds, speeds, and depth of cut when working with carbide thread mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2350 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 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  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 70056-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744854311218,"sku":"70056-C3","price":286.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e0d93d2b2efba1e032cec8c5ee367a_a5bf16cc-a91e-4f32-b5ee-e3df7d8a9054.jpg?v=1788861594","url":"https:\/\/voomisupply.com\/products\/harvey-tool-70056-c3-thread-mill-5-16-24-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
