With a 0.625-inch cutting diameter, a 0.625-inch length of cut, and a 2-flute spiral geometry at a 30-degree helix angle, this tool delivers efficient chip evacuation and clean side-wall finishes in a wide range of workpiece materials. The right-hand cut and right-hand flute configuration is the standard orientation for most CNC vertical machining centers and manual knee mills. Centercutting capability allows the tool to plunge directly into the workpiece. This end mill is installed by machinists, tool-and-die makers, and CNC operators working in job shops, production facilities, and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThe OSG 20230900 is suited for slot milling, profile milling, and peripheral cuts in ferrous and non-ferrous materials. Its regular-length classification and 3.5-inch overall length make it a practical choice for general-purpose applications where extended reach is not required. The extended reach designation and 1.625-inch reach length provide additional clearance in applications with shallow step-downs or fixtures with limited tool access. The uncoated substrate is appropriate for applications where coolant or cutting fluid is used consistently.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eUncoated finish suited for wet cutting applications with coolant\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit in close-tolerance slots\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 5\/8-inch collets, end mill holders, or hydraulic tool holders on CNC machining centers and manual vertical mills.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Torque the set screw or collet nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates carbide chipping and reduces tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eCentercutting\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\u003eReach Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.621 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.600 - 0.700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 2023\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 20230900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738191561010,"sku":"20230900","price":301.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b6cb944cdc72028d5e5f3359c88f4e8.jpg?v=1788796659","url":"https:\/\/voomisupply.com\/products\/osg-20230900-square-end-mill-5-8-inch-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
