With a 0.5-inch cutting diameter, 3 helical flutes, and a diamond-like carbon (DLC) coating, this tool delivers excellent chip evacuation and surface finish in aluminum, copper, brass, and similar workpiece materials. The extended-reach design features a neck diameter of 0.461 inches and a reach length of 2.205 inches, making it well suited for pocketing and profiling operations where standard-length tooling cannot access the cut zone. Right-hand flute direction and right-hand cutting action are standard. The tool is center-cutting, allowing direct plunge entry.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to OSG Series 2873 and is built for machinists working in job shops, production facilities, and aerospace or general manufacturing environments where non-ferrous material removal is routine. The stub flute length of 0.75 inches keeps deflection low during aggressive cuts. Extended reach of 2.205 inches accommodates deeper setups without requiring custom tooling. The straight-cylindrical shank with h6 tolerance provides a secure fit in standard ER collet chucks, side-lock holders, and shrink-fit toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDLC (diamond-like carbon) coating optimized for non-ferrous metal cutting\u003c\/li\u003e\n  \u003cli\u003e3-flute helical geometry with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eExtended reach: 2.205 inches neck reach with 0.461-inch neck diameter\u003c\/li\u003e\n  \u003cli\u003eStub length of cut (0.75 inches) minimizes deflection in aggressive operations\u003c\/li\u003e\n  \u003cli\u003eh6 shank tolerance for precise fit in precision toolholders\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance: 0.0000 to -0.0008 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard 0.5-inch toolholding systems.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a calibrated torque wrench when tightening collet nuts to avoid damaging the shank or toolholder bore. Confirm runout at the cutting edge with a dial indicator after installation before beginning a cut cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.4610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.2050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2873\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28730050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746653962546,"sku":"28730050","price":287.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e924f06a92f43b05ad1773d4fcc89d0a.jpg?v=1788872231","url":"https:\/\/voomisupply.com\/products\/osg-28730050-square-end-mill-0-5in-3-flute-solid-carbide-dlc","provider":"Voomi Supply","version":"1.0","type":"link"}
