Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, it is engineered to handle harder workpiece materials and elevated cutting temperatures that would wear down standard HSS tooling. The 0.5-inch diameter, 4-flute geometry and right-hand cutting direction make it well suited for peripheral roughing cuts where chip evacuation and tool rigidity are the primary concerns. Machinists and tool-and-die professionals install this type of cutter in vertical mills, knee mills, and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is used in metalworking applications where rapid stock removal is required before a finish pass. The 2.5-inch length of cut (LOC) allows for deep slotting and profiling operations on ferrous and non-ferrous metals. The 0.5-inch shank diameter matches standard ER and side-lock toolholders common in both manual and CNC setups. It is a non-centercutting design, so it is not intended for direct plunging; entry should be made through ramping, helical interpolation, or a pre-drilled hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral geometry optimized for roughing passes and high material removal rates\u003c\/li\u003e\n\u003cli\u003e2.5-inch length of cut supports deep slotting and profiling operations\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.5-inch shank for compatibility with standard toolholders\u003c\/li\u003e\n\u003cli\u003eNon-centercutting — requires ramp, helical, or pre-drilled entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard 0.5-inch toolholders used in vertical mills, knee mills, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank fully into the toolholder and verify runout with a dial indicator before cutting. Because this is a non-centercutting end mill, do not use it for direct axial plunge entry into solid material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\u003eCentercutting\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 723-6738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693247103282,"sku":"723-6738","price":111.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed083b2c80eee594e8d4819216d89750.jpg?v=1788309582","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6738-roughing-end-mill-0-5in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
