Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, it handles tough ferrous and non-ferrous materials with improved heat and wear resistance. The cutter measures 0.625 inches in diameter with a 1.25-inch length of cut and a 3-3\/8-inch overall length. Four right-hand flutes with a roughing profile break chips into smaller segments, reducing cutting forces and allowing higher feed rates compared to standard end mills. Center-cutting geometry allows plunge entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for general machining operations including slotting, profiling, and pocketing on manual mills and CNC machining centers. It is commonly used in job shops, maintenance machining, and production environments where rapid stock removal is prioritized before a finish pass. The 5\/8-inch shank diameter matches the mill diameter, making it compatible with standard collet chucks and end mill holders of that bore size. Right-hand cutting direction supports conventional and climb milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance and hardness retention during heavy cuts\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces built-up edge on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute roughing geometry breaks chips and lowers cutting pressure at high feed rates\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and cut direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eMatched shank and cutter diameter at 0.625 inches for straightforward toolholder setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling machines accepting a 5\/8-inch bore end mill holder or collet chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before inserting or removing any cutting tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use, and verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\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\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\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: 724-1143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717041520946,"sku":"724-1143","price":110.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe154b6fddaaa33981e668a834a9bb1b.jpg?v=1788534950","url":"https:\/\/voomisupply.com\/products\/value-collection-724-1143-roughing-end-mill-5-8in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
