Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this tool delivers heat resistance and wear durability in demanding machining environments. It features 4 flutes, a 0.3500-inch cutting diameter, a 3\/8-inch (0.3750-inch) shank diameter, and a 7\/8-inch (0.8750-inch) length of cut. Overall length is 3.5 inches. This tool is installed and operated by machinists and CNC programmers in job shops, production machining, and maintenance repair environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for threading operations on ferrous and non-ferrous workpieces where a single tool must produce both internal and external 1\/2-13 thread forms. The helical flute geometry allows the tool to interpolate the full thread in a single circular pass, reducing tool pressure compared to tap-and-die methods. It is appropriate for use in vertical machining centers and CNC mills with rigid tapping or helical interpolation capability. The AlTiN coating makes it particularly effective in dry or semi-dry cutting conditions at elevated spindle speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 1\/2-13 UNC threads in both internal and external configurations from a single tool\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability under cutting loads\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in abrasive or high-speed applications\u003c\/li\u003e\n  \u003cli\u003e4-flute helical design supports smooth chip evacuation and consistent thread form\u003c\/li\u003e\n  \u003cli\u003e0.3500-inch cutting diameter with 13 teeth per inch matches standard 1\/2-13 thread pitch\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suitable for external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation and programmed to cut 1\/2-13 UNC thread forms with a 3\/8-inch shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists or CNC setup technicians into a 3\/8-inch collet or end mill holder. Verify that the machine control supports helical interpolation before programming. Secure the shank fully within the holder to the recommended gauge line depth and confirm runout before cutting. Do not exceed the manufacturer-specified cutting parameters for AlTiN-coated carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\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 (TPI)\u003c\/strong\u003e: 13\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: 0.3500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.8750 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 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 (Aluminum Titanium Nitride)\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: 0.01 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: 70084-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744769081650,"sku":"70084-C3","price":376.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e0d93d2b2efba1e032cec8c5ee367a_fed29e4f-c403-4774-b57c-08fd87ca9cd6.jpg?v=1788860309","url":"https:\/\/voomisupply.com\/products\/harvey-tool-70084-c3-thread-mill-1-2-13-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
