It features a 0.031-inch cutting diameter and a 0.003-inch corner radius, making it well suited for producing fine edge breaks and small-radius profiles on hard and difficult-to-machine materials. The solid carbide construction delivers rigidity and wear resistance at small diameters. With four helical flutes cut in a right-hand direction and a 30-degree helix angle, this tool is capable of both roughing and finishing operations in a single setup. The bright uncoated finish is appropriate for use across a broad range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills wherever a miniature corner radius profile is required. It is particularly relevant in die and mold work, precision component machining, and prototype fabrication. Compatible primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub-to-standard length series makes it a practical selection for general-purpose miniature milling where tool deflection must be minimized. It is installed in a straight-cylindrical toolholder with a 1\/8-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.003-inch corner radius with a tolerance of plus or minus 0.001 inch for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003e0.031-inch mill diameter with a tolerance of plus or minus 0.0005 inch\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life at small diameters\u003c\/li\u003e\n\u003cli\u003eFour helical flutes, right-hand cut, 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of workpiece materials including aluminum and composites\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, no coolant-through — standard stub configuration for general miniature milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-cylindrical toolholders with a 1\/8-inch bore.

Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. At this diameter, runout in the toolholder has an outsized effect on tool life and surface finish, so verify holder concentricity before engaging the cut. Do not exceed the manufacturer-recommended depths of cut for the 0.031-inch diameter to avoid tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.003 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: 0.625 inches (3\/32 inches nominal)\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 (1\/8 inches nominal)\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: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 to minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 to minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Aluminum, Wood, Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Stub Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 47231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728121004338,"sku":"47231","price":76.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_8742c665-57f6-465f-bef1-90279af3a6e3.jpg?v=1788688336","url":"https:\/\/voomisupply.com\/products\/harvey-tool-47231-corner-radius-end-mill-0-031in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
