It carries a 1\/4-inch cutting diameter with a 1-1\/4-inch length of cut and a 3\/16-inch overall length of 3-1\/16 inches, making it a long-series tool suited for slots, pockets, and profiling operations where added reach is required. The 30-degree right-hand spiral helix promotes efficient chip evacuation during standard milling cuts. This is a right-hand cutting tool with a 3\/8-inch straight shank. Machinists, tool-and-die makers, and general machine shop personnel are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for milling ferrous and non-ferrous materials in manual knee mills, CNC machining centers, and benchtop mills. The long-series length type provides clearance for deeper pocket work where a standard-length tool would not reach. The bright, uncoated finish makes it well suited for applications where coating compatibility or re-sharpening cost is a consideration. It is sold as a single piece and is part of the VC-HSS-4 series of fractional-inch HSS end mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for toughness and wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral helix promotes upward chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eLong-series length type extends reach for deeper slots and pockets\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows easy re-sharpening and suits applications where coatings are not required\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch straight shank fits standard ER collets, side-lock holders, and milling chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fractional-inch square end mill for standard 3\/8-inch collet or end mill 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 toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention hardware to the machine or holder specification. Confirm runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 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: 1.250 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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: High Speed Steel, M2 Grade\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VC-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: 0.12 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: 720-3501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700241137970,"sku":"720-3501","price":29.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b81d84f178ec4fbb49966f4d1a2dc64.jpg?v=1788388014","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3501-square-end-mill-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
