With a 0.125 inch mill diameter, 3 flutes, and a 40-degree right-hand helix, this tool delivers efficient chip evacuation and smooth surface finishes in softer workpiece materials. The variable pitch (variable index) geometry reduces harmonic vibration during cuts, improving tool life and dimensional accuracy. At 2.5 inches overall length with a 1 inch length of cut, it suits a range of shallow-to-moderate-depth milling operations on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for production and job-shop environments where aluminum extrusions, plate stock, billet components, and other non-ferrous workpieces are machined regularly. The bright uncoated finish is appropriate for aluminum applications where coatings can cause built-up edge. The straight shank and fractional inch sizing make it compatible with standard ER collets, end mill holders, and shrink-fit tooling in 1\/8 inch bore. Machinists, CNC programmers, and tool-crib technicians working in aerospace, automotive, and general manufacturing will find this tool a direct fit for finish and semi-finish milling passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute helical flute design optimized for aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix for aggressive chip lift and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index (variable pitch) geometry minimizes chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance over high-speed tool paths\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish prevents aluminum adhesion and built-up edge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8 inch bore ER collets, end mill holders, and shrink-fit tooling.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque collet nuts or end mill holder set screws according to the tooling manufacturer specifications for the holder type in use. Confirm runout with a dial indicator before beginning production cuts, as excess runout on a small-diameter carbide tool accelerates chipping and premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.0 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 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\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous (Code N)\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: 0.001 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: 86960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728120545586,"sku":"86960","price":57.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e42bfdf53c6c6e31a8a589b0c5de1415.jpg?v=1788688318","url":"https:\/\/voomisupply.com\/products\/helical-solutions-86960-square-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
