With a 0.75-inch mill diameter and a 2.75-inch length of cut, this tool handles deep-pocket milling, slotting, and profiling in a single setup. The 35-degree right-hand helical flute geometry promotes efficient chip evacuation, reducing heat buildup and tool wear. A ZrN (Zplus) coating further protects the cutting edges and reduces built-up edge on sticky non-ferrous materials. This end mill is intended for use by machinists and CNC operators running production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered specifically for aluminum and non-ferrous workpiece materials, making it a go-to tool in aerospace, automotive, and general precision machining shops. The single-end, straight-shank configuration fits standard ER collet chucks, end mill holders, and shrink-fit toolholders with a 0.75-inch bore. Its 5.0-inch overall length provides reach for deeper features while maintaining rigidity. It is suited for both horizontal and vertical machining centers running aggressive feeds and speeds on non-ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e3-flute, 35-degree right-hand helix promotes fast chip evacuation in aluminum\u003c\/li\u003e\n\u003cli\u003eZrN (Zplus) coating reduces friction and built-up edge on sticky materials\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter matches mill diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003cli\u003e5.0-inch overall length with 2.75-inch length of cut supports deep-pocket operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum and non-ferrous machining applications as part of the HELICAL SOLUTIONS End Mills for Aluminum 3 Flute Square 35 Degree Helix series.

Torque the toolholder to the holder manufacturer's specifications and verify runout with a dial indicator before running at speed. Inspect collet and bore for contamination or wear before seating the shank. Confirm spindle direction is set to right-hand rotation before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.75 inches (2-3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.811 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 81374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51783365722418,"sku":"81374","price":435.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f44da248eba5cbb0356f375832547885_40ab28b7-aa8c-4b31-947e-c332ca4e13cd.jpg?v=1789188890","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81374-square-end-mill-3-4-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
