The tool features a 3\/16 inch (0.1875 inch) mill diameter, a 0.06 inch corner radius, and an AlTiN (aluminum titanium nitride) PVD coating that supports high-heat cutting conditions. With 3 right-hand helical flutes at a 30-degree helix angle and a stub flute length of approximately 0.117 inches, this end mill is built for both roughing and finishing operations where extended reach is required. A 1.5 inch reach length and 3 inch overall length make it suitable for deep-pocket and hard-to-access features on the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where tight-tolerance corner radii are required. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, and composites. The single-end, centercutting design with a straight cylindrical shank accepts standard toolholders. It is particularly well suited for miniature and detailed part work where a long-reach, stub-flute geometry reduces deflection while maintaining access to confined features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating supports elevated cutting temperatures and extends tool life\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius with a tight tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n  \u003cli\u003e1.5 inch extended reach length for deep-pocket and hard-to-access milling\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes at 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting, single-end design supports plunge entry and versatile toolpaths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard straight-bore toolholders accepting a 3\/16 inch (0.1875 inch) shank diameter.

Ensure the machine spindle is fully stopped and the tool change sequence is complete before handling the end mill. Inspect the shank and collet bore for contamination or damage before seating. Extended-reach tools are more sensitive to runout, so verify holder concentricity with a dial indicator before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/32 inches (0.117 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.5 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\u003eLength Type\u003c\/strong\u003e: Extended Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: AlTiN (PVD)\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 866012-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732445364530,"sku":"866012-C3","price":96.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6aa536101e5e90c004fe39f0183f1c97_009e8e5a-e30d-4760-82dc-cfc42b7e6280.jpg?v=1788742851","url":"https:\/\/voomisupply.com\/products\/harvey-tool-866012-c3-corner-radius-end-mill-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
