It carries a 0.030 inch corner radius and a 1\/8 inch diameter with four flutes ground for right-hand cutting and right-hand flute direction. The AlTiN PVD coating extends tool life in high-heat applications. At 1.5 inches overall length with a 3\/16 inch length of cut, this is a stub-length geometry built for rigidity and reduced deflection in tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and milling machines running miniature or small-feature work in production and toolroom environments. The centercutting design allows plunge entry. The stub length type makes it particularly effective in setups where overhang must be minimized to maintain dimensional accuracy. It is compatible with standard straight-cylindrical toolholders accepting a 1\/8 inch shank. Machinists working on mold cavities, medical components, and precision aerospace parts are the primary users of this tool geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.030 inch corner radius with a tight tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for heat resistance and extended tool life in ferrous and composite materials\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eStub length design maximizes rigidity and minimizes deflection on small-diameter cuts\u003c\/li\u003e\n\u003cli\u003e30 degree helix angle promotes smooth chip evacuation and surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 1\/8 inch shank diameter.

Ensure the toolholder bore and shank are clean and free of debris before seating the tool. Verify runout at the tool tip after clamping, as runout directly affects corner radius accuracy and tool life on miniature-diameter end mills. Consult the machine tool manufacturer and applicable shop safety standards for proper clamping torque and RPM limits for this shank diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.001 inch\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: 3\/16 inch (0.187 inch)\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: 1\/8 inch (0.1250 inch)\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\u003eLength Type\u003c\/strong\u003e: Short (Stub)\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ -0.0020 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 \/ -0.000 inch\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 980230-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738699563314,"sku":"980230-C3","price":56.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_9cda7935-0009-4226-b281-490df98fd2ee.jpg?v=1788803025","url":"https:\/\/voomisupply.com\/products\/harvey-tool-980230-c3-corner-radius-end-mill-1-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
