It features a 1\/4 inch cutting diameter, a 3\/8 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth surface finishes. The reduced neck and 2.125 inch reach length allow access to deeper pockets without sacrificing rigidity. A Zplus coating provides lubricity and heat resistance suited to aluminum cutting applications. This tool is installed and used by machinists and CNC operators working in job shop, production, and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is part of the HELICAL SOLUTIONS End Mills for Aluminum series, specifically the 3-flute, square-profile, 40-degree helix, variable pitch, reduced neck family. It is suited for finishing and roughing passes in aluminum, brass, and other soft non-ferrous alloys on vertical machining centers and CNC routers. The variable index geometry helps reduce harmonics and chatter at higher feed rates. The straight cylindrical shank fits standard ER collets and end mill holders with a 1\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e3-flute variable pitch design reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation in aluminum\u003c\/li\u003e\n  \u003cli\u003eZplus coating adds lubricity and edge protection for extended tool life\u003c\/li\u003e\n  \u003cli\u003eReduced neck profile with 2.125 inch reach enables deep pocket access\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry and ramp milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the HELICAL SOLUTIONS End Mills for Aluminum series — 3 Flute, Square, 40 degree Helix, Variable Pitch, Reduced Neck.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight cylindrical shank fully into a clean, undamaged collet or end mill holder and torque to the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program, particularly for high-speed aluminum finishing passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.125 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: Zplus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.093 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: 81474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51729254154546,"sku":"81474","price":87.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e58b1abe7386f46ee075bf69be3ec513_0accc54a-7f9a-45e5-8d92-c44542c926b9.jpg?v=1788702236","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81474-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
