Built to the HEV-5 series specification, it features a 0.25-inch mill diameter, a 0.0100-inch corner radius, and a 0.75-inch length of cut. The Tplus PVD coating is engineered for extended tool life in abrasive materials. Variable pitch geometry reduces harmonics during cutting, making this tool well suited for both roughing and finishing passes in a single setup. Centercutting capability allows plunge entry without a pre-drilled pilot. This tool is installed and operated by machinists and CNC programmers working in precision metalworking environments.\u003c\/p\u003e\n\u003cp\u003eThe 82980 is a single-end, straight-shank end mill with a 0.25-inch shank diameter and a 2.5-inch overall length. It is rated for primary use in stainless steel, superalloys, and titanium, with secondary application in non-ferrous metals and hard materials. It is compatible with high-precision toolholders and is intended for use in vertical or horizontal machining centers running right-hand cutting direction with right-hand flute spiral. The regular-length geometry makes it a practical choice for standard-depth profiling, slotting, and contouring operations where corner integrity is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute variable-pitch design reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eTplus PVD coating provides enhanced hardness and heat resistance for stainless steel and superalloy machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under high cutting loads\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute, right-hand cut with straight-cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Secure the shank fully within a high-precision toolholder to achieve the rated TIR maximum of 0.0005 inches; insufficient clamping depth will degrade runout and tool life. Verify spindle direction is set to right-hand rotation before engaging the cut. Follow shop-specific feeds, speeds, and coolant protocols appropriate for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 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: 0.2500 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\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.057 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: 82980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51735719772466,"sku":"82980","price":87.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/158f2309d2a95a0e47e66a3f43ce42b8_8f77d581-1019-4f4b-be41-29ceecf2efba.jpg?v=1788773776","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82980-corner-radius-end-mill-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
