It measures 0.1562 inches in diameter with a 0.03 inch corner radius and features 5 flutes with a variable helix geometry that reduces chatter and improves surface finish at aggressive feed rates. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life in abrasive materials. The tool is single-end, center-cutting, and runs right-hand flute direction with right-hand cutting. It is installed and operated by machinists and CNC operators working in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for steel and hard-material milling applications where edge integrity and dimensional control are critical. The close pitch and variable helix combine roughing and finishing capability in a single tool, making it well suited for profiling, slotting, and contouring in hardened workpieces. The series designation targets steels up to 55 Rc, making it applicable in die and mold work, aerospace component machining, and precision part production. For best results, it is recommended for use with a high-precision toolholder to maintain runout tolerances consistent with the tight mill diameter tolerance of 0.0000 to -0.0020 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix geometry reduces vibration and improves chip evacuation in hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating extends tool life in high-heat, abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003e5-flute, close-pitch design supports both roughing and finishing in a single pass\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for plunge entry and ramp-in operations\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.03 inches strengthens the cutting edge and reduces chipping on hardened steels\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.25 inches diameter fits standard collet and precision toolholder systems\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 shrink-fit toolholder to minimize runout and protect the tight diameter tolerances. Confirm spindle speed, feed rate, and depth of cut against manufacturer cutting data for the specific workpiece hardness before running. This tool does not support coolant-through delivery; direct external coolant or air blast to the cutting zone as required by the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1562 inches (5\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (15\/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 (1\/4 inches)\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\u003eHelix Style\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\u003ePitch\u003c\/strong\u003e: Close\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Alloy (up to 55 Rc)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 to -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 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 853310-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732524630322,"sku":"853310-C6","price":124.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/053baba7834841e0cee4b78e06db9214_18d65d17-1a97-40cf-a40d-6add7d0d5992.jpg?v=1788744004","url":"https:\/\/voomisupply.com\/products\/harvey-tool-853310-c6-corner-radius-end-mill-0-1562-in-5-fl","provider":"Voomi Supply","version":"1.0","type":"link"}
