With an 11\/16 inch cutting diameter, a 1-3\/8 inch length of cut, and a 3\/4 inch shank diameter, this tool delivers the rigidity and dimensional accuracy that machinists demand in production environments. The micrograin carbide substrate supports sharp edge retention across a range of workpiece materials. The 30-degree right-hand helix promotes efficient chip evacuation, and the centercutting geometry allows plunge entry as well as conventional profiling. This is a single-end, uncoated tool intended for use in CNC machining centers and manual mills by qualified machinists and tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose milling operations including slotting, profiling, and peripheral milling in shop and production settings. The regular length configuration and 4 inch overall length make it a practical fit for standard toolholders and collet chucks. The right-hand cutting direction and right-hand flute direction align with conventional spindle rotation on most vertical machining centers. The uncoated bright finish is appropriate for applications where dry cutting or certain cutting fluids are used and a base carbide substrate is preferred over coated alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling in addition to side milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced chatter\u003c\/li\u003e\n  \u003cli\u003e3 flutes with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish suitable for dry or fluid-assisted machining\u003c\/li\u003e\n  \u003cli\u003eRegular length at 4 inches OAL for compatibility with standard toolholding setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank solid carbide square end mill with a 3\/4 inch shank diameter, suitable for use in collet chucks, end mill holders, and shrink-fit toolholders that accept 3\/4 inch shanks on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is seated to the correct gauge length in the holder before tightening. Use a torque wrench on set-screw holders and verify runout with an indicator before beginning a cut. Follow the machine manufacturer and tooling supplier recommendations for speeds and feeds based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inch (0.6875 inches)\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 89319057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731705135410,"sku":"89319057","price":314.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c9bdff34261e0de087a4b1d6d869c75.jpg?v=1788734072","url":"https:\/\/voomisupply.com\/products\/hertel-89319057-square-end-mill-11-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
