Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention where standard HSS tooling falls short. The 1.25-inch diameter cutter carries six spiral flutes at a 30-degree helix angle, producing smooth chip evacuation and reduced chatter across long-reach cuts. At 4 inches length of cut and 6.5 inches overall length, this is a long-series end mill intended for deep-pocket and extended-reach applications. It arrives uncoated and center-cutting ready for plunge entry. Licensed machinists, tool-and-die shops, and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits production and job-shop environments handling steel, stainless, cast iron, and high-temp alloys where cobalt tooling is the standard choice. The long length of cut makes it suitable for deep-pocket milling, slotting, and side-milling operations that exceed the reach of standard-length end mills. Right-hand cut and right-hand flute configuration suit the majority of vertical and horizontal machining centers and manual knee mills running conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSix spiral flutes with 30-degree helix angle for efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut at 4 inches enables deep-pocket and extended-reach milling\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with regrinding and resharping services\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard spindle direction on CNC and manual mills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a long-series square end mill for use in machining centers, CNC mills, and manual knee mills accepting a 1.25-inch straight shank.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder and confirm runout with a dial indicator before cutting. Follow the machine tool manufacturer torque specifications for set screws or collet nuts — do not overtighten collet nuts on cobalt tooling as it can induce shank stress.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches (1-1\/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\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\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: E2162116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738893877554,"sku":"E2162116","price":296.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d37fb56146d0ea0a2ab0a1f2536bc990.jpg?v=1788806337","url":"https:\/\/voomisupply.com\/products\/hertel-e2162116-square-end-mill-1-1-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
