It features a 3\/16 inch (0.1875 inch) mill diameter with a matching straight-cylindrical shank, a 40-degree helix angle, and a variable index pitch design that reduces harmonic vibration during cuts. The reduced neck geometry provides extended reach of 1.312 inches, making it suitable for profiling and slotting operations where clearance is required. The bright, uncoated finish is optimized for non-ferrous materials where coating adhesion can be counterproductive. Machinists and CNC programmers in production and job-shop environments specify this geometry for its chip evacuation efficiency in aluminum.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for aluminum and other non-ferrous materials in both conventional and high-speed milling applications. The extended reach and reduced neck allow access to deeper features and pockets without requiring a longer overall tool. The 3-inch overall length and center-cutting capability support plunge entry as well as peripheral milling. It is suited for CNC vertical and horizontal machining centers running aluminum structural components, mold bases, and general-purpose aluminum profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute solid carbide construction with 40-degree right-hand helix for efficient chip evacuation in aluminum\u003c\/li\u003e\n  \u003cli\u003eVariable index pitch reduces harmonic chatter without requiring variable helix geometry\u003c\/li\u003e\n  \u003cli\u003eReduced neck with 1.312 inch reach length enables deep-pocket and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for non-ferrous and aluminum alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with straight-cylindrical shank for standard collet and end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-bore end mill holders, ER collet chucks, and shrink-fit holders accepting a 3\/16 inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully into the holder to the recommended gauge-line depth per the holder manufacturer specification. Verify runout with a dial indicator before production cuts, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.2187 inches (7\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.312 inches (1-5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Helical\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 82471\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51750170951986,"sku":"82471","price":78.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/421af9b8e5910b90b6351c001f807262_1fc0ed6f-bd2f-419f-b61b-23a70d1b9ade.jpg?v=1788914034","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82471-square-end-mill-3-16-inch-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
