With a 5\/16-inch cutting diameter and a 3\/4-inch length of cut, it handles slotting, profiling, and peripheral milling operations in general-purpose machining environments. The matching 3\/8-inch shank diameter and 3-1\/2-inch overall length make it compatible with standard collet chucks and end mill holders. The bright, uncoated finish is suited for cutting softer steels, aluminum, and non-ferrous materials where coating is not required. Machinists and tool-and-die professionals are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, knee mills, and manual milling machines where fractional-inch tooling is standard. The double-end design allows both ends to be used before the tool is retired, which extends service life and reduces tooling cost per operation. The right-hand cutting and right-hand flute direction are conventional for standard spindle rotation. A 30-degree helix angle provides a balance between chip evacuation and cutting edge strength, making it appropriate for a range of general-purpose milling tasks on ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design allows use of both cutting ends, maximizing tool life\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction provides toughness and wear resistance in general-purpose applications\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances chip evacuation with edge stability\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry suited for finishing passes and controlled material removal\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for fractional-inch collet chucks and end mill holders accepting a 3\/8-inch shank diameter in vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tooling should be installed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut.\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: 3\/4 inches (0.7500 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\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCDE-HSS-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: 0.06 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: 720-4028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696857579826,"sku":"720-4028","price":39.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01c1853c357b4310a4551f85b0714d45.jpg?v=1788347108","url":"https:\/\/voomisupply.com\/products\/value-collection-720-4028-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
