Built on a 45-degree helix angle geometry, this tool promotes efficient chip evacuation and smooth cutting action in softer, gummy materials where chip packing is a common problem. The Zplus ZrN coating reduces built-up edge and extends tool life in aluminum applications. With a 3\/16-inch diameter and a 1-inch length of cut, this end mill suits slotting, profiling, and pocket milling operations where a small-diameter, long-reach tool is required. Installation is handled by machinists and CNC operators in job shops, production facilities, and tool rooms.\u003c\/p\u003e\u003cp\u003eThis end mill is optimized for aluminum and non-ferrous workpiece materials, making it a direct choice for aerospace components, automotive parts, and general aluminum fabrication. The single-end, straight-shank configuration fits standard collet chucks and end mill holders sized for 3\/16-inch shanks. The 45-degree right-hand helical flutes and center-cutting capability allow plunge entry as well as conventional and climb milling passes. Overall length of 2.5 inches provides sufficient tool stick-out clearance for most light-duty vertical and horizontal machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree helix angle promotes fast chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eZplus ZrN coating reduces built-up edge and extends tool life\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e2-flute geometry maximizes chip clearance in softer, high-chip-volume materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum and non-ferrous machining applications.

Power down and lock out the spindle before inserting or removing the end mill from the holder. Ensure the collet or tool holder is clean and within the manufacturer-specified runout tolerance before tightening. Follow the machine tool builder guidelines and applicable shop safety procedures when setting cutting parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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 ZrN\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 0.031 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: 81312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732700430642,"sku":"81312","price":79.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1880f5004c9341d67ba7b5dca563338_076c184c-5473-4882-8c8b-ad525193a678.jpg?v=1788745850","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81312-square-end-mill-3-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
