Built from M42 cobalt high-speed steel, it handles harder workpiece materials and elevated cutting temperatures better than standard HSS tooling. The 5\/16 inch (0.3125 inch) cutting diameter is paired with a 3\/8 inch shank and a 1-1\/8 inch length of cut, giving machinists a compact, rigid tool suited for slotting, profiling, and hogging operations on ferrous and non-ferrous metals. The bright, uncoated finish is standard for cobalt end mills used in general shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for manual mills, CNC machining centers, and knee mills in job shops, tool rooms, and production floors. Its right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation. The non-centercutting design means it is intended for peripheral and side-milling passes rather than direct plunge entry. Three flutes provide a balance between chip evacuation and surface contact, making this tool effective on steel, stainless, cast iron, and similar materials where a roughing geometry is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e3-flute roughing geometry optimized for high material removal rates\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle use\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/8 inch shank for rigid tool holding\u003c\/li\u003e\n\u003cli\u003eNon-centercutting — use for peripheral and side milling, not direct plunge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling machines accepting a 3\/8 inch straight shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or tooling technician using a collet chuck, end mill holder, or set-screw holder sized for a 3\/8 inch shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm shank seating depth meets the tool holder manufacturer minimum engagement specification before securing. Because this is a non-centercutting end mill, do not program direct plunge moves into solid material.\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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 (OAL)\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.5 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: 723-5717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689179939122,"sku":"723-5717","price":56.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/637ccf5278a935ce1c3b3d9fad0ce635.jpg?v=1788255708","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5717-roughing-end-mill-5-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
