It features a 3\/4 inch cutting diameter, a 2-3\/4 inch length of cut, and a 40-degree helix angle optimized for chip evacuation in non-ferrous materials. The Zplus coating reduces built-up edge and extends tool life in aluminum, aluminum alloys, and similar soft metals. Variable pitch flute indexing reduces harmonic vibration during aggressive cuts. This is a single-end, centercutting tool with a straight cylindrical shank, suited for CNC machining centers and manual mills operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered specifically for aluminum and non-ferrous metal applications. The 40-degree helix promotes efficient chip flow and reduces heat at the cutting edge, making it well-suited for slotting, profiling, and pocketing operations in aluminum plate, billet, and extrusion work. The variable pitch design helps suppress chatter during high-speed and high-feed passes. It is appropriate for both job shop and production environments running aluminum aerospace, automotive, and general fabrication components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch cutting diameter with 2-3\/4 inch length of cut for deep slot and profile work\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle optimized for aluminum chip evacuation\u003c\/li\u003e\n  \u003cli\u003eZplus coating reduces built-up edge and extends tool life in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry and ramping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the HELICAL SOLUTIONS End Mills for Aluminum series, 3-flute square profile with 40-degree helix and variable pitch.

Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool. Seat the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and degrades surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-3\/4 inches (2.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\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\/Finish\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.853 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: 81418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51731756941618,"sku":"81418","price":460.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/827387c70c79aafd13d83aa48ef6aae0_76dd53ed-817b-49ba-86a2-63956a793c52.jpg?v=1788734601","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81418-square-end-mill-3-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
