It features a 0.5 inch cutting diameter with a 2 inch length of cut, a 0.5 inch shank diameter, and a 4.5 inch overall length. The 4-flute, straight-flute geometry with variable helix and variable index angles improves chip evacuation and reduces harmonic vibration during aggressive cuts. The Duarise finish enhances surface hardness and wear resistance. This tool is centercutting, allowing it to plunge directly into workpiece material. Machinists and CNC programmers specify this end mill for demanding finishing and semi-finishing passes on ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe OSG 82010721 is suited for use in CNC machining centers and manual mills where long-reach cuts or deep-cavity milling is required. Its long-length designation and 2 inch LOC make it appropriate for profiling, slotting, and peripheral milling in die and mold work, aerospace component machining, and general job shop applications. Right-hand cut and right-hand flute orientation are standard for conventional spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eDuarise finish improves wear resistance and surface lubricity\u003c\/li\u003e\n\u003cli\u003eStraight flute, 4-flute configuration balances chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eLong-length series provides reach for deep pockets and cavity work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0.5 inch shank square end mill compatible with ER, side-lock, and shrink-fit toolholders accepting a 0.5 inch shank diameter in CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, powered-down state. Verify toolholder bore cleanliness and proper torque on retention hardware per the toolholder manufacturer specifications before running. Set appropriate cutting parameters — speeds, feeds, and depth of cut — based on workpiece material and machine rigidity; do not exceed the 2 inch length of cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Duarise\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: 8201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.8 x 0.95 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 82010721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738498761010,"sku":"82010721","price":323.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fbbeb994776336553898f12b558a2c3_16b866e7-d450-4050-b284-45b83abdbf21.jpg?v=1788800303","url":"https:\/\/voomisupply.com\/products\/osg-82010721-square-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
