Built from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard M2 HSS tooling. The 2-inch cutting diameter and 8-flute coarse-pitch geometry break chips into smaller segments, reducing cutting forces and vibration during heavy roughing passes. At 4 inches length of cut and 7.75 inches overall length, this end mill is suited to deep-pocket and stepped-profile work on vertical and horizontal machining centers. Machinists and tool-and-die professionals install this tool in applications where roughing efficiency and tool life under heat are the primary concerns.\u003c\/p\u003e\u003cp\u003eThis end mill is used in metalworking and machining environments handling steel, stainless, and high-temperature alloys. Its bright uncoated finish makes it suitable for use with cutting fluids common in production shops. The right-hand cut and right-hand flute direction are standard for conventional milling setups on CNC machining centers, knee mills, and manual vertical mills. It is a single-end tool, meaning it is resharpened or replaced rather than flipped. Typical applications include roughing pockets, slots, and profiles where a finishing pass will follow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction provides elevated red hardness for improved tool life in ferrous alloys\u003c\/li\u003e\n\u003cli\u003e8-flute coarse-pitch design breaks chips aggressively and reduces vibration in roughing cuts\u003c\/li\u003e\n\u003cli\u003e2-inch cutting diameter with a matched 2-inch shank diameter for rigid, concentric mounting\u003c\/li\u003e\n\u003cli\u003e4-inch length of cut enables deep-pocket roughing in a single setup\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, center-cutting capable for plunge entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with standard water-soluble and oil-based cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-procurement roughing end mill for use in standard R8, CAT, BT, and HSK toolholders accepting a 2-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down or in a safe-state before changing tooling. Use a properly rated end mill holder or collet chuck sized for a 2-inch shank, and torque set screws to the toolholder manufacturer specification. Inspect the shank and holder bore for chips or burrs before seating the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2 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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 91192104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752873001266,"sku":"91192104","price":773.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e2568cd0178fb8ecc850f21ece3ea6d_ab9958a5-b716-4f4e-b8ca-4d6208e5e155.jpg?v=1788930765","url":"https:\/\/voomisupply.com\/products\/hertel-91192104-roughing-end-mill-2in-8-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
