Built from M42 cobalt high-speed steel, it delivers heat and wear resistance well beyond standard M2 HSS tooling. The 2-inch cutting diameter, 2-inch length of cut, and 30-degree right-hand spiral helix make this tool well suited for slotting, peripheral milling, and side milling operations where chip evacuation and tool life are critical. The centercutting geometry allows plunge entry without a pre-drilled hole. Licensed machinists and toolroom operators are the primary users for this class of end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, knee mills, and manual or CNC milling machines capable of handling a 1.25-inch shank diameter. It performs in ferrous metals including alloy steels, stainless steel, and cast iron, as well as in high-temp alloys where cobalt tooling is preferred over carbide in interrupted-cut applications. The bright uncoated finish is appropriate for general-purpose use and allows easy visual inspection of the cutting edges between operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance and extended tool life in tough materials\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rates and improves surface finish compared to 4-flute end mills in finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general ferrous and high-temp alloy applications\u003c\/li\u003e\n\u003cli\u003eRegular length configuration for standard reach milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machines and machining centers with ER, CAT, BT, or straight-shank collet systems capable of accepting a 1.25-inch shank diameter.

Secure the 1.25-inch shank in a properly sized collet chuck or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow the machine manufacturer's recommended speeds and feeds for cobalt end mills at this diameter, and confirm workholding is rigid enough to handle the cutting forces associated with a 6-flute, 2-inch 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: 6\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright \/ Uncoated\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\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: 2.08 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: E2042200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749150425394,"sku":"E2042200","price":412.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f898e51838150cc7dab8bdff40c1b52e.jpg?v=1788902661","url":"https:\/\/voomisupply.com\/products\/hertel-e2042200-square-end-mill-2-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
