Built from M42 cobalt high-speed steel with a TiN coating, it handles tough ferrous and non-ferrous materials with consistent edge retention. The 7\/8 inch cutting diameter pairs with a 3\/4 inch shank and a 1-7\/8 inch length of cut, giving machinists a rigid, reach-appropriate tool for slotting, profiling, and peripheral roughing cuts. Five flutes increase chip load per pass while the right-hand cutting direction and right-hand flute spiral provide predictable chip evacuation. This tool is installed and operated by machinists and tool-and-die professionals in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for general-purpose milling of steels, alloy steels, and similar materials where stock removal rate is the priority over finish quality. It is sized for use in standard vertical machining centers, knee mills, and CNC milling machines accepting 3\/4 inch collets or end mill holders. The regular-length geometry makes it a practical fit for the majority of conventional roughing operations where extended reach or variable helix is not required. It does not center-cut, so plunge entry is not recommended without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e5-flute design increases feed rate capability and material removal efficiency\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank diameter provides secure clamping in standard end mill holders and collet chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix for conventional milling setups\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration — one cutting end, standard regular length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit roughing end mill for milling machines and machining centers equipped with 3\/4 inch end mill holders, collet chucks, or Weldon-style holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and machine power isolated per shop safety protocols. Seat the 3\/4 inch shank fully into the holder before tightening to the manufacturer-specified clamping torque for the holder type in use. Because this end mill is not center-cutting, avoid direct plunge cuts into solid material. Verify runout with a dial indicator after installation to maximize tool life and surface consistency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt HSS (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: No\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: 0.05 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: 06822035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750566986034,"sku":"06822035","price":109.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b041c9b424e738d99dcaced83d86d77e.jpg?v=1788916783","url":"https:\/\/voomisupply.com\/products\/hertel-06822035-roughing-end-mill-7-8-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
