It features a 1\/8 inch diameter, a 0.005 inch corner radius, and four flutes with a right-hand spiral configuration. The cutting edge is finished with an amorphous diamond (PVD) coating, which improves hardness, reduces friction, and extends tool life across a wide range of workpiece materials. With a length of cut of 1\/2 inch and an overall length of 1.5 inches, this tool is built for tight-tolerance work in confined areas. Machinists and toolroom operators rely on this style of end mill for both roughing and finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. It performs in steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The single-end, straight-cylindrical shank fits standard toolholders, making it a straightforward drop-in for shops already running miniature end mill programs. It is part of the HARVEY TOOL Miniature End Mills - Corner Radius - Stub and Standard series, which targets applications where corner edge protection and controlled radius blending are critical to part quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.005 inch corner radius with a tolerance of plus or minus 0.0010 inch for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating for extended wear resistance across steel, stainless, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e1\/8 inch straight-cylindrical shank fits standard miniature toolholders\u003c\/li\u003e\n\u003cli\u003eNormal pitch, no chipbreaker, no variable helix — optimized for stable, predictable cuts at miniature diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard toolholders accepting a 1\/8 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the toolholder collet and torque to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as runout errors are amplified at small diameters and can affect corner radius accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0010 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: 0.5 inches (0.8125 inches decimal)\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Amorphous Diamond (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\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 Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Aluminum, Wood, Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0100 \/ -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\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 32405-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749446189362,"sku":"32405-C4","price":75.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_d51cd46e-9ef9-47fc-8e8a-dfae39fa0311.jpg?v=1788906196","url":"https:\/\/voomisupply.com\/products\/harvey-tool-32405-c4-corner-radius-end-mill-1-8-in-4-fl","provider":"Voomi Supply","version":"1.0","type":"link"}
