It features a 3\/16 inch cutting diameter, a 7\/32 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation in aluminum. Three flutes with a variable pitch (variable index) design reduce harmonic vibration during cutting, improving surface finish and tool life. The reduced neck geometry extends reach to 1.5 inches, allowing access to deeper features without sacrificing rigidity. The bright, uncoated finish is well-suited for aluminum, where coatings can cause built-up edge. This tool is installed and used by machinists and tool-and-die professionals in CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills cutting aluminum, soft alloys, and similar non-ferrous materials. The single-end, right-hand cut and right-hand flute configuration suits conventional and climb-milling applications. The reduced neck and extended reach make it appropriate for pocketing, slotting, and profiling operations where clearance is limited. It is sold individually and is part of the HELICAL SOLUTIONS End Mills for Aluminum series with a 3-flute, square-end, 40-degree helix, variable pitch, reduced neck design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-degree helix angle optimized for efficient chip evacuation in aluminum\u003c\/li\u003e\n  \u003cli\u003eVariable pitch (variable index) flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eReduced neck with 1.5 inch reach length for deep-feature and pocketing applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish prevents built-up edge on aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool for CNC machining centers and manual mills performing aluminum and non-ferrous milling operations.

Ensure the spindle and machine are fully powered down and locked out before changing tooling. Confirm runout within acceptable limits for the holder and spindle before engaging the cut. Inspect the cutting edges for chips or damage before each use, as carbide is brittle and sensitive to improper handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\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: 7\/32 inches (0.2187 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Bright\/Uncoated\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-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\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: 83557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51738335871282,"sku":"83557","price":80.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/421af9b8e5910b90b6351c001f807262_6284fe1c-1bf1-4398-8038-088c9455b6c2.jpg?v=1788798381","url":"https:\/\/voomisupply.com\/products\/helical-solutions-83557-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
