Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended tool life under heavy chip loads. The mill measures 1.5 inches in diameter with a 0.75-inch shank, a 2-inch length of cut, and a 4.25-inch overall length. Three coarse-pitch flutes channel chips efficiently and reduce cutting forces. Right-hand cut and right-hand flute geometry make this a standard-orientation tool for conventional vertical and horizontal milling setups. Centercutting capability allows direct plunge entry without a pilot hole.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for roughing passes on steel, stainless, and other tough materials where maximum metal removal rate is the priority. The TiN coating reduces friction and extends edge life in production and job-shop environments. It is installed by machinists and tool-and-die professionals in CNC machining centers, knee mills, and manual vertical mills. The 0.75-inch shank fits standard ER and Weldon-style toolholders commonly found in these machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat and wear resistance in difficult alloys\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e3-flute coarse-pitch design promotes aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard milling orientation\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 0.75-inch straight shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill fitting standard 0.75-inch ER collet chucks and Weldon-style end mill holders used in vertical and horizontal milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the milling machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the toolholder to the recommended minimum engagement depth before torquing the set screw or collet nut. Inspect the cutting edges and coating for chips or damage before each use, and never exceed the recommended depth-of-cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eCentercutting\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: 84511807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729155359026,"sku":"84511807","price":229.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e0bd97a58b0a775ae780df04de54d65.jpg?v=1788701014","url":"https:\/\/voomisupply.com\/products\/hertel-84511807-roughing-end-mill-1-1-2-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
