With a 2-inch cutting diameter, 8 flutes, and a 4-inch length of cut, this tool is suited for slotting, peripheral milling, and profiling applications where rigidity and heat resistance are priorities. The M42 cobalt grade provides elevated hardness and red-hardness compared to standard HSS, making it a reliable choice when cutting speeds and feed rates push conventional tooling. The bright, uncoated finish works well across a range of general-purpose milling operations without the added cost of a surface coating.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits horizontal and vertical knee mills, bed mills, and CNC machining centers where a 1.25-inch shank toolholder is available. The long-series length of cut at 4 inches accommodates deeper pockets and tall workpiece features that standard-length end mills cannot reach. It is right-hand cut with right-hand flute direction and a 30-degree helix angle. The non-centercutting geometry means it is intended for side milling and peripheral passes rather than direct plunge entry. Machine shops, tool-and-die operations, and maintenance machining departments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for superior heat resistance and wear life in tough materials\u003c\/li\u003e\n  \u003cli\u003e8-flute geometry increases surface finish quality and allows higher feed rates on rigid setups\u003c\/li\u003e\n  \u003cli\u003e4-inch length of cut in a long-series format for deep pocket and tall-wall milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting forces for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with a broad range of cutting fluids and materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, non-centercutting design for standard peripheral milling use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any milling machine or CNC machining center equipped with a 1.25-inch straight-shank toolholder. Confirm spindle taper, holder bore, and machine rigidity are appropriate for a 2-inch diameter cobalt end mill before use.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized end mill holder or collet chuck rated for a 1.25-inch shank diameter. Ensure the toolholder and spindle are clean and free of debris before seating the tool. Because this is a non-centercutting end mill, avoid direct plunge cuts into solid material. A licensed machinist or qualified machine operator should verify speeds, feeds, and depth-of-cut parameters before running production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\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: E299914065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748814192946,"sku":"E299914065","price":427.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0fe0a06ecdaff28728be7ebe314a911.jpg?v=1788898849","url":"https:\/\/voomisupply.com\/products\/hertel-e299914065-square-end-mill-2in-8-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
