With a 0.04-inch mill diameter and a 0.003-inch corner radius, this stub-length, single-end tool is built for tight-tolerance work where edge integrity and dimensional accuracy are critical. The four-flute, right-hand helical design with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN (aluminum titanium nitride) PVD coating enhances heat resistance and extends tool life in ferrous and stainless applications. This tool handles both roughing and finishing cuts in a single setup.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and high-speed spindles where miniature tooling is required. It targets mold and die work, medical component machining, aerospace detail parts, and other precision applications involving steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The straight cylindrical shank fits standard 1\/8-inch toolholders. Its stub-length geometry improves rigidity and reduces deflection when working in shallow-depth cavities or fine-feature profiling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.003-inch corner radius with a tolerance of plus or minus 0.001 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal resistance for dry or near-dry cutting in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n  \u003cli\u003eStub-length geometry minimizes deflection in high-precision, low-depth-of-cut applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8-inch bore toolholders.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully and evenly in the toolholder collet to the recommended gauge length before tightening. At miniature diameters, runout control is critical — verify total indicated runout after tool assembly to prevent premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches (tolerance: +0.0005 \/ -0.0005 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.003 inches (tolerance: +0.001 \/ -0.001 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.113 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (tolerance: +0.010 \/ -0.000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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 (PVD)\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\u003eChipbreaker\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Stub and Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 47240-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728081125682,"sku":"47240-C3","price":60.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_e03a6d83-addc-4e53-a2ff-ff62fe4454a4.jpg?v=1788687581","url":"https:\/\/voomisupply.com\/products\/harvey-tool-47240-c3-corner-radius-end-mill-0-04in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
