Manufactured from M42 cobalt high-speed steel, this tool handles demanding cuts in tough ferrous and non-ferrous materials where standard HSS tooling falls short. A titanium nitride (TiN) coating reduces friction and extends tool life at the cutting edge. The 2-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows plunge milling in addition to peripheral and face cuts, giving machinists flexibility across multiple operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for job shops, toolrooms, and production machining applications requiring reliable material removal in steel, alloy steel, cast iron, and similar materials. The 3\/4-inch shank diameter fits standard ER collets and milling chucks commonly found on vertical machining centers, knee mills, and CNC mills. With a 1-1\/2-inch length of cut and a 3-3\/4-inch overall length, this is a regular-length tool appropriate for typical depth-of-cut requirements without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved hardness and heat resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces cutting friction and improves wear resistance\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides open chip clearance for higher feed rates in softer materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for milling applications requiring a 1-inch diameter, 3\/4-inch shank square end mill with a regular-length profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the collet or chuck to the recommended engagement depth before tightening to prevent pullout under cutting loads. Ensure the spindle and workholding are fully stopped before changing tooling. Follow machine manufacturer guidelines for maximum RPM, feed rate, and depth of cut for cobalt end mills in the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: 0.53 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: E4030909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753054503218,"sku":"E4030909","price":143.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceb6fbd7ae1ce3890c3b7d5b7311d217.jpg?v=1788932465","url":"https:\/\/voomisupply.com\/products\/hertel-e4030909-square-end-mill-1-in-2-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
