Built to a 0.047-inch diameter with a 0.141-inch length of cut and a 0.010-inch corner radius, this single-end, centercutting tool handles both roughing and finishing passes in a single setup. The 30-degree helix and four right-hand spiral flutes promote efficient chip evacuation and surface finish quality. An AlTiN (aluminum titanium nitride) PVD coating extends tool life in abrasive and elevated-temperature cutting environments. The straight cylindrical shank measures 0.125 inches in diameter, and the tool runs 1.5 inches overall length.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, non-ferrous metals, and composite materials. Its stub and standard miniature series geometry makes it a practical choice for mold and die work, aerospace component finishing, medical device machining, and any application requiring accurate corner radii at small diameters. The centercutting geometry allows plunge entry, which broadens its use in slotting and pocket milling operations. It fits standard toolholders accepting a 0.125-inch shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.047-inch mill diameter with 0.010-inch corner radius for tight-tolerance profiling\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for extended tool life in steel, stainless, and cast iron applications\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with normal pitch for balanced cutting and chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge entry and full slot milling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n  \u003cli\u003e0.125-inch straight cylindrical shank fits standard collet-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet-style toolholders accepting a 0.125-inch straight cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the shank fully into the collet or toolholder to the recommended grip length to minimize runout and deflection at this small diameter. Verify spindle speed and feed rates against the cutting conditions for the workpiece material before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 \/ -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0100 \/ -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 27247-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728149348658,"sku":"27247-C3","price":60.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_632229a7-f769-4513-b011-086a12f3c81e.jpg?v=1788688821","url":"https:\/\/voomisupply.com\/products\/harvey-tool-27247-c3-corner-radius-end-mill-0-047-in-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
