It features a 1\/8 inch mill diameter, a 3\/8 inch length of cut, and a 1\/64 inch (0.0150 inch) corner radius that protects part edges and reduces stress concentrations at inside corners. The variable helix geometry helps break up chatter and harmonics during aggressive cuts. At 1-1\/2 inches overall length with a 1\/8 inch straight-cylindrical shank, this single-end tool fits standard collet chucks and high-precision toolholders used in CNC machining operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for shops running aluminum alloy components where both roughing and finishing passes are required in a single tool. The TiB2 (titanium diboride) PVD coating resists aluminum adhesion and galling, making it well suited for high-speed aluminum machining. It also performs in steel, stainless steel, cast iron, wood, and composite workpieces. The 42-degree variable helix and right-hand flute direction are optimized for climb milling strategies common in CNC milling centers and VMCs. Machinists and toolroom operators working in precision shops are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix design reduces chatter and harmonic vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eTiB2 PVD coating resists built-up edge and aluminum adhesion\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius (0.0150 inch) with tolerance of plus or minus 0.0010 inch for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003e3 flutes with helical flute type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable  -  supports plunge entry and ramping operations\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1\/8 inch shank with h6 tolerance for precise collet fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Secure the shank in a high-precision collet or toolholder rated for the 1\/8 inch shank diameter; confirm runout before operation. Power down and lock out the machine spindle before tool changes per facility lockout\/tagout procedures. Verify tool projection and reach requirements against the workpiece setup before starting the program.\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0150 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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 0.0020 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees, variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiB2 (PVD)\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\u003eExtended Reach\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 Materials\u003c\/strong\u003e: Aluminum, Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 912408-C8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51743234982194,"sku":"912408-C8","price":62.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f78dc1691e7b1fded74fb24858b664_c7974b47-aa84-42ae-acae-50bcbe74f631.jpg?v=1788844304","url":"https:\/\/voomisupply.com\/products\/harvey-tool-912408-c8-corner-radius-end-mill-1-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
