With a 5\/16 inch cutting diameter, a 90-degree point angle, and a 4-flute geometry, this tool transitions efficiently between center-drilling and peripheral milling without a tool change. The AlTiN coating improves heat resistance and surface hardness, extending tool life in ferrous and high-temperature alloy applications. It is used by machinists and tool-and-die professionals working on CNC machining centers and knee mills.\u003c\/p\u003e\n\u003cp\u003eThis drill mill is suited for precision work in job shops, production machining environments, and toolroom applications where a single tool must handle hole entry and slot or profile milling. The 13\/16 inch length of cut and 2-1\/2 inch overall length make it appropriate for moderate-depth features in steel, stainless, cast iron, and similar materials. The 5\/16 inch shank diameter matches the cutting diameter for straightforward collet or end mill holder setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-flute design supports both drilling entry and milling operations in one tool\u003c\/li\u003e\n  \u003cli\u003e90-degree point angle enables chamfering, spot drilling, and countersinking\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides elevated heat resistance for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance over high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eMatched shank and cutting diameter at 5\/16 inch simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill mill for CNC machining centers and manual knee mills accepting a 5\/16 inch shank via collet chuck or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Secure the shank fully in a collet or end mill holder to the manufacturer-recommended engagement depth before operation. Verify spindle runout is within acceptable tolerance before cutting, as excessive runout reduces tool life and surface finish quality. Follow the machine shop safety procedures and the tool manufacturer feed-and-speed guidelines for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/16 inch (0.8120 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 15320-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737587417394,"sku":"15320-C3","price":98.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d97fbb5c2e8dfbcb35968fbea415ef2.jpg?v=1788790919","url":"https:\/\/voomisupply.com\/products\/harvey-tool-15320-c3-drill-mill-5-16-in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
