The cutting diameter measures 1\/8 inch with a matching 1\/8-inch straight cylindrical shank, a 3\/8-inch length of cut, and a 1-1\/2-inch overall length. Three spiral flutes with a variable helix geometry reduce chatter and harmonics during both roughing and finishing passes. The 0.0100-inch corner radius adds edge strength and helps prevent chipping at the cutting perimeter. Right-hand cut and right-hand flute direction make this a standard single-end centercutting tool suited for CNC machining centers and manual mills requiring tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for material-specific applications in aluminum alloys and is also rated for steel, stainless steel, cast iron, wood, and composites. The variable helix design makes it particularly effective in aluminum where chip evacuation and surface finish are critical. It fits high-precision toolholders and is appropriate for shops running tight-tolerance work in aerospace, mold making, medical, and general machining environments. The bright uncoated finish keeps the tool ready for use without post-treatment and works well in applications where coating adhesion to aluminum could cause built-up edge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces vibration and chatter during roughing and finishing\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius with tight tolerance of plus or minus 0.0010 inch protects the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for aluminum and non-ferrous materials where bare carbide performs best\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral, single end configuration for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders. Part of the Harvey Tool Variable Helix End Mills for Aluminum Alloys - Corner Radius series and the Material Specific End Mills series.

Ensure the machine spindle is fully stopped and the toolholder is clean and undamaged before seating the shank. The 1\/8-inch shank requires a collet or toolholder rated to h6 shank diameter tolerance for proper runout control. Follow shop-standard torque procedures for the specific toolholder type in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 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: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.0010 to minus 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ minus 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Type\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Cast Iron, Steel, Stainless Steel, Wood, Composite\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: 904708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51736906924338,"sku":"904708","price":50.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f78dc1691e7b1fded74fb24858b664_3d256e79-d406-4efd-98e6-2b8ee88245a5.jpg?v=1788781777","url":"https:\/\/voomisupply.com\/products\/harvey-tool-904708-corner-radius-end-mill-1-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
