It carries a 0.0470-inch cutting diameter with a 0.0100-inch corner radius and a 0.7813-inch length of cut, ground from solid carbide for rigidity and wear resistance. The four-flute, right-hand spiral configuration supports both roughing and finishing operations. An AlTiN physical vapor deposition (PVD) coating improves heat resistance and extends tool life in ferrous and hard materials. The 1\/8-inch straight shank fits standard toolholders used in CNC machining centers and high-speed spindles. This tool is installed by machinists and CNC programmers working in precision part production.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for miniature and micro-scale milling work where a standard-reach tool cannot access the feature. The long-reach geometry, with a 0.2500-inch reach length and 1.5-inch overall length, makes it suitable for deep-pocket milling, slotting, and profiling in steel, stainless steel, cast iron, non-ferrous metals, and composite materials. It is centercutting, allowing direct plunge entry, and is appropriate for both prototype shops and production environments running small, complex components requiring tight corner radii and smooth surface finishes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability in precision milling\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for elevated heat resistance when cutting steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius with a tolerance of plus or minus 0.0010 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eFour-flute, right-hand spiral design supports material removal and surface finish in a single pass\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge and full slot milling without a pre-drilled entry\u003c\/li\u003e\n  \u003cli\u003eExtended long-reach configuration with 0.2500-inch reach length for deep-pocket and restricted-access features\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances chip evacuation with cutting force in miniature applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 1\/8-inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the 1\/8-inch shank fully and evenly in the toolholder collet or chuck, and verify runout with a dial indicator before cutting, as runout is especially critical at this diameter. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for miniature carbide end mills; do not exceed the tool's specified length of cut of 0.1410 inches per pass without engineering review.\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: 0.0100 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: 0.1410 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: 0.1250 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.2500 inches (1\/4 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: AlTiN (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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eLength Type\u003c\/strong\u003e: Extended Long Reach\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\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: 876047-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51741171876146,"sku":"876047-C3","price":92.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f331afd7097a5997c6d4265a4f8b038b_1810b18d-9e87-416e-b826-b20033205a5d.jpg?v=1788829805","url":"https:\/\/voomisupply.com\/products\/harvey-tool-876047-c3-corner-radius-end-mill-0-0470-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
