Built from M42 cobalt high-speed steel, it handles tough ferrous metals and heat-resistant alloys where standard HSS tooling falls short. The 5\/16 inch diameter cutting edge spans a 1-1\/8 inch length of cut, with a 3\/8 inch shank diameter for secure chuck or collet engagement. A TiN coating extends tool life by reducing friction and heat buildup at the cutting edge. With 3 right-hand flutes and a center-cutting geometry, this end mill can plunge directly into workpiece material.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for machinists and tool-and-die professionals working on CNC machining centers and manual knee mills. It performs best in slotting, profiling, and pocketing operations where high chip loads and rapid stock removal are the priority. The wavy or serrated flute geometry typical of roughing end mills reduces cutting forces and vibration, making it a practical choice for harder materials or less rigid setups. Overall length is 2-15\/16 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank fits standard end mill holders and collets\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1-1\/8 inch length of cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or direct-use roughing end mill for 3\/8 inch end mill holders, ER collet chucks, and side-lock holders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using appropriate end mill holders or collet chucks rated for the 3\/8 inch shank diameter. Ensure the machine spindle is fully powered down and locked before changing tooling. Follow shop-standard runout and tool-length offset procedures after seating the end mill. Verify cutting direction matches the right-hand spindle rotation of the machine before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 724-1056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690566320434,"sku":"724-1056","price":140.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6f65aa63746aeb01ff32e6f75184534.jpg?v=1788271805","url":"https:\/\/voomisupply.com\/products\/value-collection-724-1056-roughing-end-mill-5-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
