It carries a 0.062-inch cutting diameter and a 0.005-inch corner radius, with 7 flutes arranged in a variable helix configuration that reduces harmonic chatter during aggressive cuts. The AlTiN PVD coating provides thermal resistance suited to the elevated heat generated when machining hard alloys. With a 0.25-inch straight cylindrical shank and 2.5 inches of overall length, the tool fits standard collet chucks and high-precision toolholders used in CNC milling operations. Licensed machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to Harvey Tool's End Mills for Hardened Steels - Corner Radius series, designed specifically for steels, stainless steels, cast iron, and hard alloys in the 45-68 Rc hardness range. The close pitch and variable helix geometry support both roughing and finishing passes in a single tool, making it well suited for die, mold, and precision aerospace component work where tight tolerances on hardened workpieces are required. It is a single-end tool with a short length-of-cut classification, favoring rigidity over reach in confined pockets and contoured surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute variable helix design reduces chatter and improves surface finish on hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating resists heat and wear during high-speed machining of hard alloys\u003c\/li\u003e\n  \u003cli\u003e0.005-inch corner radius with a tolerance of plus or minus 0.001 inches protects cutting edges and reduces stress concentration\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity needed for steels in the 45-68 Rc range\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with close pitch for chip control\u003c\/li\u003e\n  \u003cli\u003eCompatible with high-precision toolholders; straight cylindrical shank with h6 tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Rated for hardened steels from 45 to 68 Rc per Harvey Tool's End Mills for Hardened Steels - Corner Radius series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine powered down and spindle at a complete stop. Seat the shank fully in a clean, high-precision collet or toolholder and torque to the toolholder manufacturer's specification. Coolant-through is not supported; ensure adequate external coolant or air blast is directed at the cutting zone. Inspect the corner radius and cutting edges for chips or wear before each setup, as carbide end mills in hardened-material service are sensitive to interrupted cuts and improper runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix\u003c\/strong\u003e: 20 degrees, Variable\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: AlTiN (PVD)\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\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\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\u003eHardness Range\u003c\/strong\u003e: 45-68 Rc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 to minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 to minus 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 903162-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728457597234,"sku":"903162-C6","price":128.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/499f013b7e105b3a1af90e884567558c.jpg?v=1788691497","url":"https:\/\/voomisupply.com\/products\/harvey-tool-903162-c6-corner-radius-end-mill-0-062in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
