Built with a 40-degree helix angle and variable pitch (variable index) geometry, it reduces chatter and improves surface finish in non-ferrous materials. The cutting diameter is 0.375 inches (3\/8 inches), length of cut is 0.5 inches (1\/2 inches), and overall length is 3 inches. A Zplus coating provides lubricity and edge protection suited to aluminum alloys. The reduced neck profile extends reach to 1.625 inches while maintaining rigidity. This tool is intended for CNC machinists and toolroom operators running aluminum roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for aluminum and other non-ferrous materials where chip evacuation and edge sharpness are critical. The 3-flute configuration balances chip clearance with cutting efficiency in softer materials. The reduced neck and extended reach design make it well-suited for pocketing, slotting, and profiling operations where clearance above the cut zone is limited. It carries a straight-cylindrical shank at 0.375 inches diameter, compatible with standard ER collets and end mill holders used in VMCs, HMCs, and manual mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute solid carbide construction for rigidity and long tool life in aluminum\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry minimizes harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eZplus coating enhances lubricity and edge durability in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eReduced neck design extends reach to 1.625 inches for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports plunge entry without pre-drilling\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, 40-degree Helix, Variable Pitch, Reduced Neck.

Seat the straight shank fully into a collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification before running. Verify runout with a dial indicator before committing to a production cut. Confirm spindle speed and feed rates match the manufacturer recommended parameters for the specific aluminum alloy and cut depth being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 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: 1\/2 inches (0.500 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\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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\u003eSeries\u003c\/strong\u003e: End Mills for Aluminum - 3 Flute - Square - 40 deg Helix - Variable Pitch - Reduced Neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.148 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: 81476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732729430322,"sku":"81476","price":95.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e58b1abe7386f46ee075bf69be3ec513_77e270aa-1cd0-477b-b311-1725f1560ff2.jpg?v=1788746097","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81476-square-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
