It features a 0.625-inch mill diameter, a 0.1250-inch corner radius, and four flutes with a variable pitch and right-hand cutting direction. The tool is finished with an APLUS PVD coating, which improves wear resistance and extends tool life in ferrous materials. At 3.5 inches overall length with a 1.625-inch length of cut, it fits standard toolholding setups. Licensed HVAC techs and machinists working in precision environments will find this tool well-suited to demanding tolerances, with a maximum TIR of 0.0005 inches.\u003c\/p\u003e\u003cp\u003eThis end mill is built for cutting steel, cast iron, and related ferrous alloys, including low-alloy steel, medium alloy steel, tool steel, and cast iron. It is a single-end tool in the HSV-4 series, intended for use in high-precision toolholders. The 0.625-inch straight cylindrical shank with h6 tolerance ensures consistent runout when seated in a collet or shrink-fit holder. Typical applications include die and mold work, part profiling, and finishing passes on ferrous workpieces in CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1250-inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches for repeatable edge geometry\u003c\/li\u003e\n\u003cli\u003eAPLUS PVD coating rated for steel and cast iron  -  improves surface hardness and heat resistance at the cutting edge\u003c\/li\u003e\n\u003cli\u003eVariable pitch flute spacing reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle use\u003c\/li\u003e\n\u003cli\u003eMaximum TIR of 0.0005 inches supports tight-tolerance finishing work\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides stiffness and wear resistance over high-speed tool steel alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the shank fully into a high-precision collet or shrink-fit holder and verify runout before cutting. Power down and lock out the spindle before tool changes. Do not exceed the recommended length of cut of 1.625 inches  -  extending engagement beyond this depth increases deflection and can damage the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1250 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 \/ 0.0620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\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\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\u003eMaterial\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\u003eSeries\u003c\/strong\u003e: HSV-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eWeight\u003c\/strong\u003e: 0.434 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: 43589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51741895131442,"sku":"43589","price":284.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2858d4771745ab9247fc82e6a5af2123_eab73c34-8cd9-420f-b2f6-8484cc632564.jpg?v=1788834136","url":"https:\/\/voomisupply.com\/products\/helical-solutions-43589-corner-radius-end-mill-0-625in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
