Built from M42 cobalt high-speed steel, it delivers thermal and wear resistance that outperforms standard HSS tooling in demanding cuts. The single-end, center-cutting design allows plunge entry, and the 30-degree spiral flute geometry promotes efficient chip evacuation. With a 1.375-inch cutting diameter and a 2-inch length of cut, this tool handles shoulder milling, slotting, and profiling operations requiring both depth and rigidity.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose and production machining in job shops, maintenance environments, and toolrooms. The right-hand cut and right-hand flute configuration matches standard spindle direction on most vertical and horizontal milling machines. The 0.75-inch shank diameter and 4.375-inch overall length make it a regular-length tool appropriate for setups where clearance is not a constraint. Six flutes provide a higher tooth count for improved surface finish at moderate feed rates. The uncoated finish makes it straightforward to resharpen on a tool grinder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat and wear resistance versus standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eSix-flute design improves surface finish and allows higher table feed rates\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry permits direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows conventional resharpening without coating removal concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt square end mill for milling machines and machining centers accepting a 0.75-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom personnel using an appropriate collet chuck, end mill holder, or milling arbor rated for the 0.75-inch shank. Confirm the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool. Verify runout with a dial indicator after clamping to minimize premature edge wear. Follow shop feed and speed tables for cobalt tooling when programming or setting manual feeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.375 inches (1-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.375 inches (4-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E299914041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729582883122,"sku":"E299914041","price":201.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ba7103c638690bbe73c88cf6902f7dd.jpg?v=1788706394","url":"https:\/\/voomisupply.com\/products\/hertel-e299914041-square-end-mill-1-3-8-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
