Manufactured from M2 high speed steel with a bright uncoated finish, it measures 0.5 inches in diameter with a 2-inch length of cut and a 4-inch overall length. The four-flute, right-hand spiral configuration at a 30-degree helix angle promotes efficient chip evacuation and a smooth finish on ferrous and non-ferrous workpieces. This tool is suited for conventional milling operations where coolant-through and extended-reach features are not required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in manual mills, knee mills, CNC machining centers, and bridgeport-style machines in job shop, maintenance, and production environments. The 0.5-inch shank diameter fits standard ER or end mill holders in that bore size. Its long-series length type provides additional reach for deeper-cavity work compared to standard-length tooling. Machinists, toolmakers, and maintenance technicians performing metal removal tasks are the primary users of this style of tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 high speed steel construction for good wear resistance in general machining applications\u003c\/li\u003e\n  \u003cli\u003e4-flute design for improved surface finish and feed rate capability\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix for efficient chip flow in conventional milling\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n  \u003cli\u003eLong-series length type provides additional reach over standard-length end mills\u003c\/li\u003e\n  \u003cli\u003eSingle-end geometry; not center-cutting, so not suited for direct plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose square end mill compatible with any milling machine or machining center that accepts a 0.5-inch shank diameter end mill holder or collet chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolmaker using an appropriate end mill holder, collet chuck, or Weldon-style holder rated for 0.5-inch shank tooling. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify holder runout with a dial indicator after seating the tool to minimize chatter and premature tool wear. This tool is not center-cutting and should not be used for direct vertical plunge cuts without a pre-drilled starting hole or ramping entry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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 (M2 grade)\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: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eWeight\u003c\/strong\u003e: 0.18 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: 720-3509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694359216434,"sku":"720-3509","price":50.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9172a2bb049c237a2aa62a8d3c14849f.jpg?v=1788323587","url":"https:\/\/voomisupply.com\/products\/value-collection-720-3509-square-end-mill-1-2-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
