The 3\/4-inch cutting diameter pairs with a 0.0150-inch corner radius and three helical flutes to produce clean edge breaks and reduced corner chipping on precision workpieces. A Zplus PVD coating provides elevated surface hardness and lubricity, extending tool life in demanding cutting environments. The H40ALV-3 series geometry features a variable index pitch, which reduces harmonic vibration and chatter at elevated feed rates. This tool is intended for use in high-precision toolholders and is well suited for machinists and CNC programmers running aluminum and non-ferrous metals as primary workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe 83552 is primarily rated for aluminum and non-ferrous metal applications, with secondary capability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Its centercutting design allows plunge entry, making it useful for pocketing, slotting, and profiling operations on vertical and horizontal machining centers. The single-end, straight-cylindrical shank with h6 tolerance fits standard collet and high-precision shrink-fit toolholders. The regular-length flute geometry and 1.7500-inch length of cut handle most common depth requirements in production and job-shop environments without requiring extended-reach tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0150-inch corner radius reduces stress concentrations and extends insert life at workpiece edges\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating optimized for aluminum and non-ferrous metal cutting with reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003eVariable index pitch suppresses chatter and harmonics during aggressive feed-rate operations\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry for pocketing and cavity work\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting with high helix style for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eh6 tolerance on both mill diameter and shank diameter ensures accurate fitment in high-precision toolholders\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 the collet or shrink-fit holder to the recommended gauge-line depth before torquing the retention mechanism. Verify runout with a dial indicator against the TIR specification before beginning a cut. Do not exceed the toolholder manufacturer's maximum RPM rating for the tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 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: h6\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 to 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 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: Zplus (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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\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\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 Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High Temperature Alloy, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H40ALV-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.712 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: 83552\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51749335105842,"sku":"83552","price":371.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/439d4f4f86cd204b1bd849d5cf89664c_3cd9c45e-f7d5-4c7c-9ecd-2fdb826b1e67.jpg?v=1788904655","url":"https:\/\/voomisupply.com\/products\/helical-solutions-83552-corner-radius-end-mill-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
