It carries a 3\/16 inch (0.1875 inch) mill diameter, a 0.03 inch corner radius, and five helical flutes with a variable helix geometry that reduces chatter and improves surface finish at aggressive feed rates. The AlTiN PVD coating adds thermal resistance and hardness at the cutting edge, extending tool life in high-heat applications. At 2.5 inches overall length with a 1\/4 inch straight cylindrical shank, this end mill seats securely in high-precision toolholders for close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited to hardened steel finishing and roughing operations in precision machining environments  -  mold and die work, tool steel components, and hardened workpieces where edge integrity and corner definition are critical. The single-end design, right-hand cutting and flute direction, and close pitch make it a direct fit for CNC machining centers running high-speed or hard-material strategies. It is appropriate for both roughing and finishing passes where dimensional accuracy at the corner radius must be maintained.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened materials up to 55 Rc\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for elevated thermal resistance and extended tool life in hard and abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces harmonic vibration and chatter during cutting\u003c\/li\u003e\n  \u003cli\u003e5-flute, close-pitch design supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eCorner radius tolerance held to plus or minus 0.001 inch for consistent corner definition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of runout before seating the end mill. Use a high-precision collet or shrink-fit toolholder as specified for this series to maintain concentricity and protect the corner radius geometry. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece material and hardness.\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 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 inch to minus 0.001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (1.0 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to minus 0.002 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCenter Cutting\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 Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.08 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: 853312-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51784282833202,"sku":"853312-C6","price":129.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/053baba7834841e0cee4b78e06db9214_a3b498f3-7ce6-4b68-9f55-9da69a40c6a6.jpg?v=1789198730","url":"https:\/\/voomisupply.com\/products\/harvey-tool-853312-c6-corner-radius-end-mill-3-16-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
