Built from solid carbide and coated with a proprietary Tplus PVD coating, it handles roughing and finishing operations in a single tool. The 0.0300-inch corner radius reduces stress concentration at the cutting edge, extending tool life in abrasive and hard materials. With a 0.5000-inch mill diameter, a 0.6250-inch length of cut, and a 2.5000-inch overall length, this stub-length tool offers rigidity for aggressive cutting strategies. Variable pitch geometry suppresses chatter across a wide range of cutting parameters.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for primary use in stainless steel, high-temperature alloys, and hardened steel, with secondary suitability in steel and cast iron. It is a single-end, right-hand cut, right-hand flute tool in the HEV-7 series. Typical applications include aerospace, medical, and die-mold work where tight tolerances and difficult materials are standard. It is intended for use with high-precision toolholders to maintain runout within the 0.0005-inch TIR maximum specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute geometry supports both roughing and finishing passes, reducing tool changes\u003c\/li\u003e\n  \u003cli\u003eTplus PVD coating provides heat and wear resistance in stainless steel and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003eVariable pitch design reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius with tight tolerance of -0.0020 to 0.0020 inch\u003c\/li\u003e\n  \u003cli\u003eStub length construction maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance for secure, precise toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the straight-cylindrical shank fully into a high-precision toolholder and torque the retention mechanism per the toolholder manufacturer specification before use. Verify runout does not exceed the 0.0005-inch TIR maximum using a dial indicator before cutting. This tool is not center-cutting and should not be used for plunge entry without a pre-drilled hole or ramping strategy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 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: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 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: -0.0620 \/ 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 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: Tplus (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\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; High-Temperature Alloy; Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel; Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.229 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 59955\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732032028978,"sku":"59955","price":176.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/577e72e240d50bb7a1a38f11a1b9031b_f1414b77-ad73-4615-880f-593cf698b5ba.jpg?v=1788738416","url":"https:\/\/voomisupply.com\/products\/helical-solutions-59955-corner-radius-end-mill-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
