Built from M42 cobalt high-speed steel, it resists heat buildup during heavy cuts, making it suitable for ferrous metals, stainless steel, and other tough alloys. The 1.5-inch diameter cutter carries 6 flutes in a right-hand cutting and right-hand flute configuration with a bright, uncoated finish. The shank measures 1.25 inches in diameter. Machinists and tool-and-die professionals use this cutter in vertical and horizontal milling machines for roughing passes before finish milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop environments where high-volume roughing cuts are required. The 6-flute geometry distributes cutting load across more edges, reducing chatter and extending tool life under heavy chip loads. The regular-length design with a 4-inch length of cut and 6.5-inch overall length fits standard milling machine setups and longer-reach fixtures. It is a single-end, non-centercutting tool, meaning it is intended for peripheral cuts and side milling rather than plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e6-flute, right-hand cut geometry for efficient chip evacuation during roughing passes\u003c\/li\u003e\n\u003cli\u003e1.25-inch shank diameter for rigid tool holding and reduced deflection\u003c\/li\u003e\n\u003cli\u003e4-inch length of cut accommodates deep slotting and side milling applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids or dry in appropriate materials\u003c\/li\u003e\n\u003cli\u003eNon-centercutting, single-end design — intended for peripheral and side milling only\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 standard milling machine setups accepting a 1.25-inch shank diameter in collet chucks, end mill holders, or set-screw holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Secure the 1.25-inch shank in a properly sized end mill holder or collet chuck and verify runout before operation. This is a non-centercutting tool — do not use for plunge cuts. Always power down and lock out the machine spindle before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 0.456 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: 06821847\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738654933298,"sku":"06821847","price":259.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/744edc72fb0a36087db2d0c124e87d08.jpg?v=1788802391","url":"https:\/\/voomisupply.com\/products\/hertel-06821847-roughing-end-mill-1-1-2-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
