With a 0.125-inch mill diameter and a 0.625-inch length of cut, this tool delivers clean, accurate profiles in applications where chip evacuation and surface finish are critical. The 40-degree helix angle and variable index geometry reduce chatter and harmonics during the cut. A ZrN (Zplus) coating provides lubricity and hardness suited to aluminum alloys and other non-ferrous workpiece materials. Installed by machinists and tool-and-die professionals in CNC machining centers and manual mills, this end mill is a single-end, right-hand cutting tool on a straight shank.\u003c\/p\u003e\u003cp\u003eThis end mill is built for aluminum and non-ferrous materials in production and prototype environments. The 0.125-inch shank diameter matches the mill diameter, making it compatible with standard collet systems sized for 1\/8-inch tooling. A 40-degree right-hand helical flute design promotes efficient chip flow away from the cut zone, which is especially important when machining sticky, gummy aluminum alloys. The 2.5-inch overall length provides sufficient reach for most shallow-to-moderate pocket and slot milling operations without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute variable index geometry reduces vibration and chatter during aluminum milling\u003c\/li\u003e\n\u003cli\u003e40-degree right-hand helix promotes aggressive chip evacuation in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eZrN (Zplus) coating enhances lubricity and tool life in aluminum and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — suitable for plunge entry operations\u003c\/li\u003e\n\u003cli\u003eSingle-end design with a straight 0.125-inch shank for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8-inch collet systems on CNC machining centers and manual milling machines.

Seat the straight shank fully and evenly in a clean, properly sized collet before torquing the collet nut to the spindle manufacturer's specification. Inspect the cutting edges and coating for chips or damage before each use. Consult tooling manufacturer feeds-and-speeds data for the specific alloy and machine setup before running this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\/Finish\u003c\/strong\u003e: ZrN (Zplus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 82390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51748579279154,"sku":"82390","price":63.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/827387c70c79aafd13d83aa48ef6aae0_f6db2488-9812-43be-b772-7444a3a2ed53.jpg?v=1788895368","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82390-square-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
