Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, this tool handles tough ferrous and non-ferrous materials where standard HSS cutters would wear prematurely. It runs a 3\/4 inch cutting diameter with a 3\/4 inch length of cut, four flutes, and a right-hand cutting and flute direction. The TiN coating reduces friction and extends tool life in high-cycle production environments. Machinists and tool-and-die professionals rely on this style of roughing end mill for high metal removal rate passes before finish milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on manual knee mills, CNC vertical machining centers, and CNC milling machines in both job shop and production settings. The regular-length geometry and 3\/4 inch shank diameter make it a practical choice for standard tool holders, collet chucks, and end mill holders. It is center-cutting, allowing plunge entry into the workpiece without a pre-drilled start hole. Typical applications include roughing slots, pockets, and profiles in steel alloys, stainless, and other hard materials where high chip load capacity is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003e4-flute design supports high chip load and efficient material removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eRegular length geometry fits standard end mill holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock tooling option for standard 3\/4 inch end mill holders, collet chucks, and milling tool holders accepting a 3\/4 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the tool holder to the manufacturer-recommended engagement depth and torque set screws to the tool holder specification. Verify runout with a dial indicator before beginning a cut, and confirm feed rate and spindle speed are appropriate for the workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches (2.8750 inches)\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.034 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: 06822241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754891346226,"sku":"06822241","price":106.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60ec4f6830f062f24821e4334ec09288.jpg?v=1788949566","url":"https:\/\/voomisupply.com\/products\/hertel-06822241-roughing-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
