Built to a stub length geometry, it features a 0.078 inch cutting diameter, a 0.01 inch corner radius, and four helical flutes with a 30-degree helix angle. The bright, uncoated finish is well-suited for applications where coating is not required or where workpiece material adhesion to coated tools is a concern. This tool is appropriate for machinists, toolroom technicians, and CNC operators working with tight-tolerance parts that require controlled corner break geometry.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills handling a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composites. Its stub length configuration improves rigidity in tight-clearance setups and short-reach applications. The single-end, right-hand cut and right-hand flute direction are standard for conventional CNC toolholding systems. It is center-cutting, enabling direct plunge entry when required by the operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.01 inch corner radius with a tolerance of plus 0.001 to minus 0.001 inch for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance for steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eFour helical flutes with 30-degree helix angle for efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eStub length at 0.279 inch length of cut improves tool stiffness and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of material types including non-ferrous and composites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 0.125 inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 0.125 inch shank fully and evenly in the toolholder collet before tightening to prevent runout. Verify tool runout with a dial indicator prior to first use, as excessive runout will accelerate edge wear and reduce corner radius accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.078 inches\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\u003c\/strong\u003e: 0.01 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.279 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\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.01 to minus 0.000 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eLength Type\u003c\/strong\u003e: Short (Stub)\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Aluminum, Wood, Composite\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: 994578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51754038362418,"sku":"994578","price":51.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_014b8d85-bce2-43df-b82c-d638241dc7b3.jpg?v=1788943114","url":"https:\/\/voomisupply.com\/products\/harvey-tool-994578-corner-radius-end-mill-0-078-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
