The cutter measures 0.0470 inches in diameter with a 0.0050-inch corner radius and carries a diamond PVD coating for extended tool life in abrasive and hard materials. With a 3-flute, right-hand spiral geometry and centercutting capability, it handles both roughing and finishing passes. A straight cylindrical shank at 0.1250 inches diameter seats securely in standard toolholders. This tool is installed and used by machinists and toolroom technicians operating CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to the Miniature End Mills - Corner Radius - Long Reach, Stub Flute series, making it suited for tight-tolerance work in confined pockets and slots where extended reach is required. The 0.5700-inch reach length and 1.5748-inch length of cut support deep-cavity milling while the stub flute design maintains rigidity. Typical applications include die and mold work, aerospace components, medical device features, and any precision part requiring a controlled edge radius in steel or non-ferrous metal. The right-hand cutting direction is standard for conventional CNC spindle operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond PVD coating rated for steel, stainless steel, cast iron, aluminum, wood, and composite workpieces\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 0.5700-inch reach length for deep-cavity and confined-pocket access\u003c\/li\u003e\n  \u003cli\u003eCorner radius tolerance held to plus or minus 0.0010 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-end, 3-flute right-hand spiral suitable for both roughing and finishing in one tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard CNC toolholders accepting a 0.1250-inch straight cylindrical shank.

Confirm the toolholder bore and collet size match the 0.1250-inch shank diameter before seating the tool. Power down and lock out the spindle before changing tooling. At miniature diameters, avoid excessive runout in the toolholder, as even small amounts of radial deviation can cause premature tool breakage or dimensional error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.5700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003c\/strong\u003e: Diamond (PVD)\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.0010 \/ minus 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0100 \/ minus 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Long Reach, Stub Flute\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: 39447-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740018573618,"sku":"39447-C4","price":108.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6aa536101e5e90c004fe39f0183f1c97_6fcb670c-c3b0-4683-b3bb-8cd79aee4ee3.jpg?v=1788821509","url":"https:\/\/voomisupply.com\/products\/harvey-tool-39447-c4-corner-radius-end-mill-0-0470-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
