Manufactured from M42 cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life in demanding cutting applications. The 1\/2-inch diameter, 4-flute configuration with a coarse pitch generates the chip clearance needed for high feed rates. With a 1-inch length of cut and 3-inch overall length, this end mill is suited for general-purpose roughing passes in ferrous and non-ferrous metals. Installation is handled by machinists and tool-and-die professionals in shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills for roughing operations on steel, stainless steel, cast iron, and similar materials. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling setups. The center-cutting geometry allows plunge entry, adding flexibility for pocketing and slotting operations in production and maintenance machining contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces friction on cutting edges\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch design promotes chip evacuation during heavy roughing cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports direct plunge entry for pocketing operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard milling setups\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch shank diameter matches standard collet and end mill holder sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 1\/2-inch end mill holders, ER collet chucks, and side-lock (Weldon) holders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using appropriate collet chucks or end mill holders rated for 1\/2-inch shank tooling. Ensure the spindle is fully de-energized and at rest before changing tooling. Shank diameter tolerance runs from -0.0001 to -0.0005 inches, so verify holder bore condition before seating the tool. Follow machine tool manufacturer torque guidelines for drawbar and set screw retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00394 to -0.00197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.88 x 0.71 x 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.019 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: 44839058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748503454002,"sku":"44839058","price":80.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5440542b370b5f153d2fb9f0278060d.jpg?v=1788894560","url":"https:\/\/voomisupply.com\/products\/hertel-44839058-roughing-end-mill-1-2-in-4-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
