With a 1\/16 inch cutting diameter and a 0.0100 inch corner radius, it delivers precise edge profiles while reducing corner chipping in demanding applications. The variable helix geometry helps suppress chatter and promotes smooth chip evacuation. At 2.5 inches overall length with a 5\/16 inch length of cut, this single-end, centercutting tool handles both roughing and finishing operations. It is sized for use in high-precision toolholders and suits CNC machining environments where tight tolerances and surface finish are critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for shops running aluminum alloy workpieces as its primary target, while remaining capable across steel, stainless steel, cast iron, wood, and composite materials. The 3-flute, right-hand spiral configuration with a 42-degree helix angle supports efficient chip removal at higher feed rates. The bright uncoated finish is well suited to non-ferrous machining where coating adhesion or chemical reaction with aluminum is a concern. It fits a 1\/8 inch straight cylindrical shank and is appropriate for use in high-precision collet chucks or end mill holders on CNC mills and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix design reduces harmonic vibration and chatter during cut\u003c\/li\u003e\n  \u003cli\u003e0.0100 inch corner radius with tolerance of plus or minus 0.0010 inch for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish is compatible with aluminum and non-ferrous materials without chemical interaction risk\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute spiral with normal pitch supports both roughing and finishing in a single tool\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 tool changer or spindle is locked out before mounting or removing the end mill. Seat the 1\/8 inch shank fully into the collet or holder to the recommended gage line depth before tightening. Verify runout with a dial indicator after clamping, as excessive runout will accelerate wear and degrade corner radius accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0620 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: 5\/16 inch (0.3120 inches)\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\/8 inch (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 or minus 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus or minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 840762\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738318438706,"sku":"840762","price":70.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f78dc1691e7b1fded74fb24858b664_18e5ac03-4428-43d7-9c08-92c6d7283da6.jpg?v=1788798207","url":"https:\/\/voomisupply.com\/products\/harvey-tool-840762-corner-radius-end-mill-1-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
