Built with 4 flutes and an AlTiN coating, it handles the heat and abrasion demands of production milling environments. The shank diameter is 0.3125 inches with a cutting diameter of 0.2850 inches, a length of cut of 0.7500 inches, and an overall length of 3.0000 inches. Coolant-through capability supports chip evacuation and tool life in deep or tight thread-milling passes. This tool is sized for machinists and CNC operators working in job shops, production facilities, or toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for cutting 3\/8-16 threads at 16 teeth per inch in a range of workpiece materials where AlTiN coating provides thermal protection. Internal thread milling in through-holes and blind holes is a primary application, along with external thread milling on cylindrical features. The minimum nominal thread diameter is 0.3750 inches. It is appropriate for use in CNC machining centers running helical interpolation routines, and is typically selected when single-point threading or tapping is impractical due to material hardness or thread tolerance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 3\/8-16 unified coarse threads — internal and external in a single tool\u003c\/li\u003e\n  \u003cli\u003e4-flute helical geometry for stable chip load distribution\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance and extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and reduces heat at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003e0.3125 inch shank diameter fits standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation, with a 0.3125 inch shank compatible with standard ER collets and end mill tool holders.

Secure the shank in a properly sized collet or end mill holder and verify runout before cutting. Confirm that the machining center is programmed for helical interpolation at the correct thread pitch before engaging the workpiece. Engage coolant-through supply when available to maximize chip clearing and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 16 TPI\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: 0.2850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 17364-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727108800818,"sku":"17364-C3","price":369.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/266bbd6f1da70cec8b2e2482f840e945.jpg?v=1788673478","url":"https:\/\/voomisupply.com\/products\/harvey-tool-17364-c3-thread-mill-3-8-16-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
