Built from M42 cobalt high-speed steel, it carries a TiN coating that improves surface hardness and extends tool life under heat. The cutter measures 0.25 inches in diameter with a 3\/8-inch shank diameter, a 1.125-inch length of cut, and a 2-15\/16-inch overall length. Three flutes with a right-hand cutting and flute direction produce the corncob-style roughing geometry that breaks chips efficiently and reduces cutting forces. Machinists and toolroom operators install this type of end mill on manual knee mills and CNC machining centers alike.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing passes on ferrous and non-ferrous workpiece materials where fast stock removal is the priority before finishing cuts. The cobalt M42 substrate handles higher cutting temperatures than standard M2 HSS, making it a practical choice for stainless steel, alloy steel, and other work-hardening materials. The TiN coating adds a layer of lubricity that helps reduce built-up edge and extend intervals between tool changes. It is not center-cutting, so plunge milling requires a pre-drilled entry point or a ramping strategy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS substrate for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e3-flute roughing geometry breaks chips and lowers cutting forces during aggressive passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits common ER and side-lock toolholders\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — requires pre-drilled entry or ramp entry for plunge operations\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 manual and CNC milling machines accepting a 3\/8-inch shank diameter toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Power down and lock out the spindle drive before seating or removing the tool from its holder. Confirm shank engagement depth meets the toolholder manufacturer minimum before torquing the retention hardware. Because this tool is not center-cutting, program a ramp or helical entry path rather than a direct plunge to avoid tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\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: 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: 0.02 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: 723-6702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690354082098,"sku":"723-6702","price":67.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adda420cf2ed1f03dc45a47cbfee4a3c.jpg?v=1788269321","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6702-roughing-end-mill-1-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
