It features a 9\/16-inch (0.5625-inch) cutting diameter and a 1\/2-inch shank diameter, with four right-hand flutes engineered to break chips into smaller segments and reduce cutting forces compared to standard end mills. The body is manufactured from M42 cobalt high-speed steel for heat and wear resistance, and the cutting edges carry a TiN (titanium nitride) coating to extend tool life. This tool is center-cutting, allowing plunge entry into workpieces. It is installed and used by machinists and tool-and-die professionals on manual or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThis roughing end mill suits general-purpose hogging operations in ferrous and non-ferrous metals, including steel alloys, cast iron, aluminum, and similar machinable materials. The 1-3\/8-inch length of cut and 3-3\/8-inch overall length make it appropriate for shallow-to-medium-depth pocketing, slotting, and profiling passes where maximizing material removal rate is the priority before a finishing pass. The 1\/2-inch shank fits standard ER collets, side-lock holders, and end mill holders common across most milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction resists heat buildup during high-feed roughing cuts\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eFour right-hand flutes with roughing geometry break chips and lower cutting pressure\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter fits widely available collet and tool holder systems\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration — one active cutting end per tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for milling machines accepting 1\/2-inch shank end mills via ER collet chucks, Weldon-style side-lock holders, or equivalent end mill holding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine spindle fully stopped and the machine locked out per standard shop safety practice. Seat the 1\/2-inch shank fully into the tool holder and torque the retention mechanism to the holder manufacturer specification. Inspect the TiN coating and cutting edges for chips or wear before each use — a damaged roughing end mill should not be run. Speeds and feeds should be calculated for the specific workpiece material and machine rigidity; consult published HSS cobalt cutting data tables for starting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiN (Titanium Nitride)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 724-1131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694673625394,"sku":"724-1131","price":76.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ae99e52632f131386834b767d53bb73.jpg?v=1788326995","url":"https:\/\/voomisupply.com\/products\/value-collection-724-1131-roughing-end-mill-9-16in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
