Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat resistance and edge retention needed for cutting tough ferrous and non-ferrous materials. The tool measures 1.5 inches in cutting diameter with a 1.5-inch length of cut and a 3.75-inch overall length. Three coarse-pitch flutes channel chips efficiently while reducing chatter during heavy roughing passes. The 0.75-inch straight shank fits standard end mill holders and collet chucks found on knee mills, vertical machining centers, and CNC equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations where material needs to be removed quickly before a finishing pass. The coarse pitch geometry breaks up chips into smaller segments, reducing heat buildup and tool load in the cut. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation. Center-cutting capability allows plunge entry directly into the workpiece without a pre-drilled hole. It is appropriate for use on manual mills and CNC machining centers in job shops, tool rooms, and production environments handling structural steel, alloy steel, stainless, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch, 3-flute design for aggressive chip evacuation during roughing passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a wide range of metals without coating-related adhesion concerns\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for compatibility with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter fits common end mill holders and ER collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for any machine tool equipped with a standard 0.75-inch end mill holder, side-lock holder, or compatible collet chuck running right-hand rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the tool. Seat the shank fully into the holder to the minimum engagement depth recommended by the holder manufacturer, and torque the retention screw or collet nut to the holder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on roughing geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 91192369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735284384050,"sku":"91192369","price":250.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e2568cd0178fb8ecc850f21ece3ea6d_67560d64-8e14-4b6a-ad8c-3b11d6ef2d7c.jpg?v=1788771493","url":"https:\/\/voomisupply.com\/products\/hertel-91192369-roughing-end-mill-1-1-2-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
