It features a 1\/4 inch cutting diameter, a 1\/2 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation in non-ferrous materials. The variable index flute spacing reduces harmonic chatter during high-speed passes, improving surface finish and tool life. A Zplus coating provides added lubricity and heat resistance at the cutting edge. At 2 inches overall length with a straight cylindrical 1\/4 inch shank, this tool fits standard collet chucks and end mill holders. It is centercutting and right-hand cutting, making it suitable for plunge, slot, and profile operations in aluminum and similar soft alloys.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for machining aluminum and other non-ferrous materials in CNC milling applications, both production and prototype environments. The 3-flute geometry with 40-degree helix and variable index pitch is optimized for high metal removal rates in aluminum, where chip packing and built-up edge are common concerns. Machinists and tooling technicians in job shops, aerospace component shops, and manufacturing facilities routinely spec this series for finishing and semi-finishing passes on aluminum plate, billet, and extrusion stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in aluminum cutting\u003c\/li\u003e\n  \u003cli\u003e3-flute variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eZplus coating adds lubricity and reduces material adhesion at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the Helical Solutions End Mills for Aluminum 3 Flute Square 40 Degree Helix Variable Pitch series.

Ensure the shank is fully seated and the tool is secured before spindle engagement. Confirm spindle rotation direction matches the right-hand cutting geometry before running the program. Do not exceed the tool manufacturer recommended speeds and feeds for the target material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\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\u003c\/strong\u003e: Zplus\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 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: 81400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51733143126322,"sku":"81400","price":64.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/827387c70c79aafd13d83aa48ef6aae0_90259202-2a3a-4834-b305-044499bd4ce5.jpg?v=1788751833","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81400-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
