Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, it delivers extended tool life under high heat and interrupted-cut conditions. The cutter measures 1 inch in diameter with a 4-inch length of cut and a 6.5-inch overall length. Five coarse-pitch flutes break up chips efficiently, reducing cutting forces and heat buildup at the tool-workpiece interface. This end mill is center-cutting and configured for right-hand cutting and right-hand flute direction. Machinists and tool-and-die professionals use this type of cutter for roughing passes on ferrous and non-ferrous stock before finishing operations.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for use in vertical and horizontal milling machines, CNC machining centers, and manual knee mills where high-volume material removal is the priority. The coarse pitch geometry makes it appropriate for profiling, slotting, and peripheral milling in steel, stainless, and other tough alloys. The 1-inch shank diameter matches standard R8, CAT, BT, and HSK toolholders in that bore size. It is a single-end tool, meaning it is resharpened or replaced rather than flipped when the cutting end is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and hardness retention at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e5-flute coarse-pitch design accelerates chip evacuation and lowers radial cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix configuration for standard spindle direction\u003c\/li\u003e\n\u003cli\u003e1-inch shank diameter matches 1-inch bore toolholders directly with no reduction needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1-inch bore milling toolholders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank fully into a clean, undamaged collet, end mill holder, or milling chuck and torque the retention mechanism to the toolholder manufacturer's specification. Inspect the TiN coating and cutting edges before each use — do not run a chipped or cracked cutter. Follow your shop's lockout\/tagout procedure before changing tooling in any spindle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 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\/Finish\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\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\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: 72846322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730717835570,"sku":"72846322","price":203.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a4689b497c453ac57571cc375a0c0a6.jpg?v=1788721731","url":"https:\/\/voomisupply.com\/products\/hertel-72846322-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
