With a 0.500-inch mill diameter, a 1.250-inch length of cut, and a 0.0300-inch corner radius, this tool balances rigidity and reach for both roughing and finishing passes. The Tplus PVD coating delivers elevated hardness and heat resistance, making this end mill well suited for stainless steel, high-temperature alloys, and hardened steels. Variable pitch geometry reduces harmonic chatter, and through-coolant capability supports chip evacuation in deep-pocket and slotting operations. Machinists and toolroom technicians running precision CNC milling operations select this tool for its consistent performance in difficult-to-machine workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe 84321 is designed for use in CNC machining centers handling stainless steel, high-temperature alloys, and hardened steel workpieces. Its single-end, center-cutting design allows plunge entry and full slot milling without a pilot hole. The 0.500-inch straight cylindrical shank is compatible with high-precision toolholders, and the HEVC-6 series geometry is optimized for finishing and semi-finishing passes where tight tolerances and surface finish quality are critical. This tool fits applications in aerospace, medical, mold-and-die, and general precision machining environments where workpiece hardness and heat generation are primary concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300-inch corner radius with a tolerance of -0.0020 to 0.0020 inches for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eTplus PVD coating rated for stainless steel, high-temperature alloys, and hardened materials\u003c\/li\u003e\n  \u003cli\u003eVariable pitch flute spacing reduces vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable for improved chip evacuation and thermal management\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting, right-hand flute direction allows direct plunge and slot entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers stiffness and wear resistance in hard material applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Confirm the machine spindle is fully stopped and the tool change sequence is complete before handling or seating the end mill. Use a high-precision collet or shrink-fit toolholder to achieve maximum runout control; maximum TIR is 0.0005 inches. Inspect the tool shank and toolholder bore for contamination or damage before each setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 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 to 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 to 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eSeries\u003c\/strong\u003e: HEVC-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.258 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 84321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728132112690,"sku":"84321","price":364.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d32bd40e8cc1887b967ed33fedffffab_f774b9e4-db78-4644-b8b6-60834c39964f.jpg?v=1788688530","url":"https:\/\/voomisupply.com\/products\/helical-solutions-84321-corner-radius-end-mill-1-2-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
