Built from M2 high speed steel with a bright uncoated finish, it measures 5\/16 inches in diameter with a 1-3\/8 inch length of cut and a 3-1\/8 inch overall length. The 3\/8 inch shank diameter provides solid tool holder engagement, and the 30-degree helix angle promotes efficient chip evacuation during cuts. This is a single-end, right-hand cutting tool suited for machinists running manual mills or CNC machines at moderate speeds and feeds.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for slotting, profiling, and peripheral milling on ferrous and non-ferrous materials where HSS tooling is preferred over carbide. The long-series classification extends reach compared to standard-length end mills, making it useful when additional clearance is needed in pockets or stepped workpieces. It is a fractional-inch, spiral-flute tool without chipbreaker geometry, making it a straightforward choice for general shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for toughness in general machining applications\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eLong-series length type for extended reach in deep pockets or stepped features\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation — compatible with standard spindle direction\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — suitable for use with cutting fluid or light dry cutting\u003c\/li\u003e\n\u003cli\u003eSingle-end design — replace when worn rather than flip\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard fractional-inch shank end mill compatible with 3\/8 inch collets and end mill holders on manual knee mills, bridgeport-style machines, and CNC machining centers accepting 3\/8 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered off before inserting or removing the tool from the holder. Secure the shank to the full recommended engagement depth in the collet or end mill holder to minimize runout and prevent pullout under load. Do not exceed the tool's rated cutting parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches (3.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\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: 720-3503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702474572082,"sku":"720-3503","price":41.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/300a8ff698e729f617d820a6abd2009e.jpg?v=1788411203","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3503-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
