Part of the HEV-5 series, it features a 5-flute variable-pitch design with a Tplus PVD coating that extends tool life in high-heat, high-abrasion cutting environments. The mill diameter is 0.25 inches, the length of cut is 0.5 inches, and the overall length is 2.5 inches. The corner radius is 0.015 inches, which reduces stress concentration at the cutting edge and improves surface finish at part corners. This tool is used by machinists and CNC operators in precision manufacturing and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 82982 is designed for both roughing and finishing operations on stainless steel, superalloys, titanium, non-ferrous metals, and hard materials. Its centercutting capability allows plunge entry, making it suitable for slotting, profiling, and pocket milling in a single tool. The straight cylindrical shank with h6 tolerance is compatible with high-precision toolholders, making it appropriate for high-speed machining centers where runout control is critical. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute variable-pitch geometry reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eTplus PVD coating enhances wear resistance and heat dissipation in stainless and superalloy applications\u003c\/li\u003e\n\u003cli\u003e0.015-inch corner radius reduces edge chipping and improves corner finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability in hard-material applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance seats accurately in high-precision collet and hydraulic toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders on CNC machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully in a clean, undamaged collet or toolholder bore and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut, particularly in high-tolerance or hard-material applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium, Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 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\/0.0620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-5\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: 82982\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51730876727602,"sku":"82982","price":85.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/158f2309d2a95a0e47e66a3f43ce42b8_f8217cd8-1074-477d-891f-78fb268c2df6.jpg?v=1788724251","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82982-corner-radius-end-mill-0-25in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
