It carries a 9\/64 inch (0.1406 inch) cutting diameter with a 0.0300 inch corner radius and a 1.75 inch length of cut, delivering clean edges and controlled radii in tight-tolerance applications. The AlTiN PVD coating provides heat resistance and extended tool life at elevated cutting speeds. With four flutes in a right-hand spiral configuration and a 30-degree helix angle, this end mill is suited for both roughing and finishing passes in a single setup.\u003c\/p\u003e\u003cp\u003eThis end mill fits production and toolroom environments where miniature features, slots, and contours are required. It is centercutting and single-ended, allowing plunge entry without a pre-drilled start hole. The 3\/16 inch straight-cylindrical shank seats directly into standard collet chucks and toolholders. Typical applications include die and mold work, precision component machining, and finishing of hardened or abrasive workpiece materials where a tight corner radius is a design requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating for high-temperature resistance and reduced tool wear in ferrous and abrasive materials\u003c\/li\u003e\n\u003cli\u003e0.0300 inch corner radius with a tolerance of plus or minus 0.0010 inch for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle improves chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability in miniature-diameter tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard collet chucks and toolholders accepting a 3\/16 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the end mill. Confirm runout with a dial indicator before beginning a cut, as concentricity is critical at miniature diameters. Follow the machine tool builder's guidelines and applicable shop safety procedures when changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.0010 to minus 0.0010 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ minus 0.0020 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: 0.4250 inch (approximately 1.75 inches nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0100 \/ minus 0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\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\u003eWeight\u003c\/strong\u003e: 0.03 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: 966730-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740612755762,"sku":"966730-C3","price":65.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_e1ae4b08-e9ee-4a80-9ae1-56983c9c83a6.jpg?v=1788826207","url":"https:\/\/voomisupply.com\/products\/harvey-tool-966730-c3-corner-radius-end-mill-9-64-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
