It carries a 1\/8 inch mill diameter, a 0.015 inch corner radius, and a 4-flute helical geometry that delivers a fine surface finish while maintaining edge integrity under high-hardness cutting conditions. The AlTiN PVD coating provides thermal resistance and extended tool life in ferrous and abrasive materials. At 2.5 inches overall length with an extended reach configuration, this single-end mill is suited for deep-reach finishing passes in tight cavities and hardened workpiece features.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for CNC machining centers and high-precision toolholders used in die and mold work, aerospace component finishing, and precision part manufacturing. Its extended reach of 0.625 inches and a 0.113 inch length of cut make it appropriate for contouring and profiling hardened steel cavities where reach beyond standard stub-length tooling is required. Right-hand flute direction and right-hand cutting geometry are standard. The normal pitch and fixed helix geometry provide predictable chip load calculations in production finishing programs.\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 and hard alloy materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating enhances heat resistance and extends tool life in ferrous applications\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius with a tight tolerance of plus or minus 0.0002 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eExtended reach design at 0.625 inches reach length for deep-cavity finish passes\u003c\/li\u003e\n  \u003cli\u003e4-flute helical geometry optimized for finishing  -  not roughing  -  in hard and stainless materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry where required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eIntended for use with high-precision toolholders on CNC machining centers.

Secure the 1\/4 inch straight-cylindrical shank in a high-precision toolholder to the manufacturer-specified runout tolerance  -  excessive runout will accelerate edge wear on a finishing tool of this diameter. Confirm spindle speed and feed rate calculations are based on the 1\/8 inch cutting diameter, not the shank diameter. This tool is designated for finishing passes only; do not use for aggressive material removal or roughing operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0002 to -0.0002 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: 0.113 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0100 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eHelix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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: Finishing\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 996408-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740471132466,"sku":"996408-C6","price":147.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5a900b2d1ec289ac7e34021f2fb9149.jpg?v=1788825224","url":"https:\/\/voomisupply.com\/products\/harvey-tool-996408-c6-corner-radius-end-mill-1-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
