Built from M42 cobalt high-speed steel with a TiN coating, it delivers elevated heat and wear resistance compared to standard HSS tooling. The 1-inch cutting diameter and 5-flute geometry produce a coarse chip-breaking action that reduces cutting forces and limits chatter during heavy roughing passes. The shank diameter is 0.75 inches and the length of cut is 2 inches, with an overall length of 4.25 inches. It is centercutting, allowing plunge entry into the workpiece. Machinists and tool-and-die professionals install this end mill in manual or CNC vertical milling machines.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for roughing operations in steel, stainless, cast iron, and other tough materials where heat generation is a concern. The M42 cobalt steel grade provides added red hardness, making it a reliable choice for high-temperature applications and interrupted cuts. Its right-hand cut and right-hand flute direction match the standard spindle rotation of most vertical mills and machining centers. The TiN finish extends tool life and reduces built-up edge on the cutting faces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for increased red hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003e5-flute roughing geometry breaks chips aggressively to lower cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 0.75-inch straight shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling choice for vertical milling machines and CNC machining centers accepting a 0.75-inch shank end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-change procedures. Ensure the spindle is fully stopped and the machine is powered down or placed in a safe state before changing tooling. Secure the shank fully within the collet or end mill holder to the depth recommended by the holder manufacturer, and verify runout with a dial indicator before beginning cuts. Do not exceed the rated cutting parameters for the workpiece material and machine rigidity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 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 (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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: Yes\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-1239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707637694770,"sku":"724-1239","price":210.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5786fc0cb646bd10f5ce923cbd87df12.jpg?v=1788441364","url":"https:\/\/voomisupply.com\/products\/value-collection-724-1239-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
