Built from M42 cobalt high-speed steel, this single-end mill features a 5\/16 inch cutting diameter, a 2 inch length of cut, and a 30-degree helix angle with four spiral flutes for efficient chip evacuation. The bright, uncoated finish makes it straightforward to inspect for wear. Machinists and tool and die professionals use this end mill for slotting, profiling, and peripheral milling in ferrous and hard materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines, CNC machining centers, and manual knee mills that accept a 3\/8 inch shank. The extra-long overall length of 3.75 inches makes it suitable for applications requiring extended reach into deep pockets or stepped features where a standard-length tool cannot access the workpiece. It is center-cutting, allowing plunge entry as well as conventional side milling. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with 30-degree helix angle for smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eExtra-long length type at 3.75 inches OAL for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for easy visual wear inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration; right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines and machining centers that accept a 3\/8 inch shank diameter.

Power down the spindle and lock it out before changing tooling. Use appropriate cutting speeds and feeds for cobalt tooling in the workpiece material to avoid premature edge chipping. Do not exceed the rated length of cut when taking full-depth passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 723-3403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697203478834,"sku":"723-3403","price":58.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/119650cddaf4ccca23842ccd418f8b7b.jpg?v=1788350482","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3403-square-end-mill-5-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
