Built with a 7-flute variable helix geometry, it reduces chatter and improves surface finish in difficult-to-machine materials. The cutting diameter is 0.1250 inches with a 0.0300-inch corner radius, a 3\/8-inch length of cut, and a 1-1\/2-inch overall length. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life at elevated cutting temperatures. This tool is a single-end, right-hand cut, right-hand flute design intended for use in close-pitch finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing applications in aerospace, medical, die and mold, and precision machining environments where tight tolerances and superior surface finish are required. It performs in steel, stainless steel, cast iron, and hard alloys. The 41-degree helix angle and variable helix construction help manage heat and vibration in high-temp alloy cuts. It is designed for use with high precision toolholders to maximize runout control and tool life. The straight cylindrical shank measures 1\/8 inch in diameter, matching the cutting diameter for straightforward collet clamping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute variable helix design reduces harmonic vibration during finishing passes\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal resistance for high-temp alloy machining\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius protects cutting edges and improves corner strength\u003c\/li\u003e\n  \u003cli\u003e41-degree helix angle optimized for heat-resistant and hard materials\u003c\/li\u003e\n  \u003cli\u003eClose-pitch flute spacing increases material removal rate in finishing operations\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity and dimensional accuracy at 0.1250-inch diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for finishing operations in steel, stainless steel, cast iron, and hard alloys.

Seat the straight cylindrical shank fully and evenly in a high-precision collet or toolholder before tightening to minimize runout. Verify spindle speed, feed rate, and depth of cut against the material-specific cutting data for solid carbide end mills before engaging the workpiece. Do not use this tool in a worn or damaged toolholder, as runout at this diameter will significantly reduce tool life and surface finish quality.\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 (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 41 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\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\u003eVariable Helix\u003c\/strong\u003e: Yes\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 \/ -0.0010 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: +0.0100 \/ -0.0000 inches\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: 0.01 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: 892708-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738626097458,"sku":"892708-C6","price":67.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23187d7ca15ad03c6ae7f4f4d0102f93_f1f8f655-7305-49df-8c24-566f71c93999.jpg?v=1788802009","url":"https:\/\/voomisupply.com\/products\/harvey-tool-892708-c6-corner-radius-end-mill-1-8-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
