Built from high speed steel (HSS) with a bright, uncoated finish, this tool offers a 5\/16 inch cutting diameter and 1-1\/2 inch length of cut, making it well suited for deep-reach roughing and finishing passes. With four right-hand spiral flutes, it delivers smooth chip evacuation and consistent surface finishes. The 3\/8 inch shank diameter and 3-1\/4 inch overall length fit standard milling machine and machining center collet and end mill holders. Machinists and tooling technicians are the primary users of this style of cutter.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is appropriate for use in manual knee mills, CNC vertical machining centers, and light-duty horizontal setups. The long-series length type gives the reach needed for mold work, cavity milling, and contoured part features where a standard-length tool cannot access the geometry. Right-hand cutting direction is compatible with conventional and climb milling strategies. The bright uncoated finish is a general-purpose choice suited to a wide range of ferrous and non-ferrous workpiece materials where specialized coatings are not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch ball nose diameter for contour and profile milling\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness and regrindability\u003c\/li\u003e\n  \u003cli\u003eLong-series overall length of 3-1\/4 inches for extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suits general-purpose ferrous and non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 3\/8 inch shank for standard collet and holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock ball end mill compatible with standard 3\/8 inch end mill holders, collet chucks, and shrink-fit holders used in manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a properly sized collet or end mill holder, torquing the drawbar or retention knob to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when tight tolerances are required.\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 inches (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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\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\u003eVariable Index\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\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: 320-3718\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708840214834,"sku":"320-3718","price":71.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b44b13235bce7b6bde9a1cf13795fa3c.jpg?v=1788448614","url":"https:\/\/voomisupply.com\/products\/value-collection-320-3718-ball-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
