Manufactured from M42 cobalt high-speed steel and coated with TiAlN for extended tool life at elevated cutting temperatures, this mill features five flutes in a coarse-pitch, right-hand spiral configuration. The coarse pitch geometry breaks chips aggressively, reducing heat buildup and chatter during roughing passes. With a 1-inch cutting diameter and a 3-inch length of cut, it handles deep-pocket and side-milling operations in a single setup. Machinists and tool-and-die professionals will find it well-suited to production roughing applications where stock removal rate matters.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical machining centers and manual knee mills for roughing operations in steel, stainless, cast iron, and high-temperature alloys. The center-cutting geometry allows plunge entry without a pre-drilled start hole. The 1-inch shank diameter fits standard R8, CAT, BT, and HSK toolholders with a 1-inch bore. It is a common choice in job shops and production environments where cobalt tooling is specified over carbide for interrupted cuts or materials that are prone to carbide chipping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction withstands heat and intermittent cutting loads better than standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and allows higher surface speeds in dry or minimal-lubrication conditions\u003c\/li\u003e\n\u003cli\u003e5-flute coarse-pitch design promotes aggressive chip breaking and reduced chatter on roughing passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting end enables direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut supports deep-pocket roughing without tool changeover\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1-inch-bore milling toolholders including R8, CAT, BT, and HSK systems on vertical machining centers and knee mills.

The shank should be seated to the full recommended insertion depth in the toolholder and secured to the manufacturer torque specification for the holder type in use. Inspect the cutting edges and coating for chips or wear before mounting. Do not exceed the toolholder's rated speed and torque limits for this shank diameter.\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\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003c\/strong\u003e: TiAlN\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\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003ePackage Weight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 62888243\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746692137266,"sku":"62888243","price":196.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24cd09ba0809675df923c4b9d5082fdd.jpg?v=1788872839","url":"https:\/\/voomisupply.com\/products\/hertel-62888243-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
