Built on the HSV-4 series platform, it features a 0.5000 inch mill diameter, a 1.2500 inch length of cut, and a 0.0600 inch corner radius. The four-flute geometry runs in a right-hand cutting direction with a variable pitch and spiral flute configuration, supporting both roughing and finishing passes in a single tool. An APLUS PVD coating protects the cutting edges during aggressive feeds in ferrous materials. The overall length is 3 inches and the straight cylindrical shank diameter is 0.5000 inch. Licensed machinists and CNC tooling specialists select this end mill for production work where edge life and surface finish consistency matter.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for milling low-alloy steel, medium alloy steel, tool steel, and cast iron. It is suited for vertical and horizontal machining centers running high-precision toolholders. The single-end, non-centercutting design positions it for side milling, peripheral profiling, and slotting operations where corner radius blending is required. The variable pitch index helps suppress harmonic chatter during deeper cuts in harder ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous cutting applications\u003c\/li\u003e\n\u003cli\u003eAPLUS PVD coating classification extends tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eVariable pitch index reduces chatter in demanding milling conditions\u003c\/li\u003e\n\u003cli\u003e0.0600 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inch\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry supports smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eCompatible with high-precision toolholders for minimal runout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the straight cylindrical shank fully into a precision collet or toolholder to the minimum insertion depth recommended by the toolholder manufacturer. Verify runout with an indicator before beginning a production cut, noting that the maximum TIR for this tool is 0.0005 inch. Follow the tooling manufacturer and machine builder guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: APLUS (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\u003eVariable Index\u003c\/strong\u003e: Yes\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\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Low-Alloy Steel, Medium Alloy Steel, Tool Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inch\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSV-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.247 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 43527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732257603890,"sku":"43527","price":154.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b01823e1f87f8854aeaa58b3f96b56d.jpg?v=1788740913","url":"https:\/\/voomisupply.com\/products\/helical-solutions-43527-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
