Built from M42 cobalt high-speed steel and finished with a TiCN coating, it handles tough ferrous and non-ferrous workpieces where standard HSS tooling falls short. The coarse pitch, 3-flute geometry produces wide chip gullets that clear material efficiently, reducing heat buildup during heavy cuts. With a 1.25-inch cutting diameter and 3-inch length of cut, this tool suits deep-pocket roughing passes on vertical mills and machining centers. Machinists and tool-and-die professionals specify this grade for interrupted cuts and harder alloys.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing applications in job shops, maintenance machining environments, and production floors where tool life and metal removal rate matter. The right-hand cut and right-hand flute geometry are standard for conventional milling setups. The centercutting design allows plunge entry, adding flexibility for pocket milling operations without a pre-drilled entry point. A 1.25-inch shank diameter fits standard ER or side-lock holders used on vertical knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life on abrasive and harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eCoarse pitch, 3-flute design maximizes chip clearance during heavy roughing passes\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard milling spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1.25-inch shank for secure tool holder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for standard 1.25-inch bore ER collet chucks, side-lock holders, and Weldon-style tool holders used on manual and CNC vertical milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and the machine is locked out before inserting or removing the tool. Seat the shank fully into the holder to the recommended minimum engagement depth before torquing the retention mechanism. Inspect the TiCN coating and cutting edges for chips or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiCN\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: 75987800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732526694706,"sku":"75987800","price":246.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a418de364a3e343f7d2e2d84d8f1bf9a.jpg?v=1788744035","url":"https:\/\/voomisupply.com\/products\/hertel-75987800-roughing-end-mill-1-1-4-in-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
