Built from M42 cobalt high-speed steel, it delivers heat and wear resistance beyond standard HSS tooling. The 30-degree right-hand helix promotes smooth chip evacuation and reduces chatter during full-slot and peripheral milling. With a 3-inch length of cut and 5.5-inch overall length, this is a standard-reach tool suited for production environments where tool life and edge retention are the priority. Machinists and toolroom professionals working on CNC machining centers and manual mills are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited for milling operations in job shops, toolrooms, and production facilities working with steels, stainless steels, and similar tough materials. Its centercutting geometry allows plunge entry without a pre-drilled hole, which adds flexibility when slotting or ramping into a workpiece. The 1-inch straight shank fits standard R8, CAT, BT, and ER collet toolholders commonly found in vertical machining centers and knee mills. The regular-length configuration keeps deflection low in most standard-depth cavity and slot work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat resistance and extended tool life in tough materials\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry increases feed rate capability and improves surface finish compared to 4-flute designs\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral helix promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with standard cutting fluids and oils without coating compatibility concerns\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use in conventional CNC and manual milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid end mill replacement for 1-inch straight-shank toolholders including R8 collets, ER collet chucks, and similar systems used in vertical machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer's torque and runout specifications. Ensure the machine spindle is fully stopped and the control is in E-stop before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder to minimize runout and prevent pullout under load. Do not exceed the recommended depth of cut or feed rate for the 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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\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\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\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\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: E2042980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732759019826,"sku":"E2042980","price":157.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72deedb9f297db27271a75020890effd.jpg?v=1788746394","url":"https:\/\/voomisupply.com\/products\/hertel-e2042980-square-end-mill-1-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
