Constructed from M42 cobalt high-speed steel with a bright\/uncoated finish, it handles tough ferrous and non-ferrous metals where heat resistance and edge retention matter. The 1-inch mill diameter pairs with a 1-inch Weldon flat shank for secure, slip-resistant clamping in compatible tool holders. A 30-degree helix angle promotes smooth chip evacuation and reduces chatter during aggressive cuts. This end mill is intended for use by machinists and tool-and-die professionals in milling operations requiring both roughing and finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for vertical milling machines, horizontal mills, and machining centers in job shop, production, and maintenance environments. The 6-flute geometry increases feed rates and improves surface finish compared to lower-flute-count tools, making it appropriate for finishing passes on steel, stainless, and similar hard materials. The Weldon flat shank provides positive engagement with set-screw style tool holders, reducing pullout risk during heavy cuts. It is a non-centercutting design and should not be used for plunge cutting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat resistance and edge durability in hard materials\u003c\/li\u003e\n\u003cli\u003e6-flute design supports higher feed rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive set-screw engagement and minimizes pullout\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluid in ferrous applications\u003c\/li\u003e\n\u003cli\u003eSingle-end, square end geometry for shoulder milling and finishing operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank roughing finishing end mill compatible with 1-inch bore, set-screw style Weldon tool holders used on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Secure the Weldon flat against the tool holder set screw to the holder manufacturer's specified torque using the appropriate hex key. Confirm runout with a dial indicator before beginning the cut. Do not use this tool for plunge or slot entry cuts, as it is a non-centercutting design.\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: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-4257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717813862706,"sku":"724-4257","price":80.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/111af397b2356e0d9981551fba5dd92b.jpg?v=1788545989","url":"https:\/\/voomisupply.com\/products\/value-collection-724-4257-roughing-finishing-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
