Built from M42 cobalt high-speed steel, this end mill delivers the heat and wear resistance required for cutting harder ferrous and non-ferrous materials. The 4-flute, right-hand cutting geometry with a bright uncoated finish makes it well suited for roughing passes where chip clearance and edge strength are the primary concerns. The 0.625-inch diameter with a matching 0.625-inch shank provides consistent rigidity throughout the cut. It is installed and operated by machinists and tool-and-die professionals in shop environments.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is used in vertical and horizontal milling machines for roughing operations on steel, stainless, cast iron, and similar materials. The 1.25-inch length of cut accommodates standard depth-of-cut requirements in most roughing applications. The single-end configuration focuses tool mass at the cutting end, which supports stability during high-material-removal-rate passes. It is a practical choice for production shops and job shops running manual or CNC milling equipment where a reliable, uncoated cobalt rougher is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved heat resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand cutting geometry optimized for roughing passes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluid or dry applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 0.625-inch shank diameter matching the cutter diameter\u003c\/li\u003e\n  \u003cli\u003e1.25-inch length of cut with 3.375-inch overall length for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting — requires a pre-drilled or pre-bored entry point\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 0.625-inch straight shank end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis end mill is installed by machinists using a compatible end mill holder, collet chuck, or side-lock holder sized for a 0.625-inch shank. Ensure the spindle and workpiece are fully secured and the machine is powered off before changing tooling. This is a non-centercutting tool and must not be plunged directly into solid material. Always verify runout after tool installation to maximize tool life and surface finish quality.\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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 (OAL)\u003c\/strong\u003e: 3.375 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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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: 0.3 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: 723-5743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716951834930,"sku":"723-5743","price":86.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2324b6c5703494f441973910a0d827c0.jpg?v=1788533902","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5743-roughing-end-mill-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
