Built to Series 484 specifications, it features a 0.9843-inch (25 mm) mill diameter and a 2.9921-inch (76 mm) length of cut, placing it in the extra-long reach category for deep-cavity and extended-reach work. The four-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is center-cutting, allowing plunge entry, and runs right-hand cut with right-hand flute direction. It arrives uncoated and is ready for use or custom coating as required by the application.\u003c\/p\u003e\u003cp\u003eThe 484-9843 is suited for milling ferrous and non-ferrous materials in vertical machining centers and CNC milling setups. Its extra-long length of cut makes it particularly useful for deep-pocket milling, slot milling, and profiling operations where standard-length end mills cannot reach. The solid carbide construction provides the rigidity needed to maintain tight tolerances at elevated spindle speeds. This tool is appropriate for job shops, tool-and-die operations, and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.9843-inch (25 mm) diameter with 2.9921-inch (76 mm) length of cut for deep-reach milling\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral flute design with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC spindle use\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eExtra-long length classification for deep-pocket and extended-reach applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish — compatible with user-applied coatings or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC vertical milling machines and machining centers accepting a 25 mm (0.9843-inch) shank diameter.

Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Use a properly sized collet or end mill holder rated for the 25 mm shank diameter and confirm tool runout with a dial indicator after clamping. Follow the machine tool manufacturer's recommended speeds and feeds for solid carbide end mills at this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.9843 inches (25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.9921 inches (76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 153 mm (approximately 6.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25 mm (0.9843 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 484\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches L x 1.25 inches W x 1.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 484-9843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735683170610,"sku":"484-9843","price":682.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f1d8548cfaf3984380bd4e973b43cc7_95d15104-b0fa-4ac4-bea7-0cb712559c80.jpg?v=1788773616","url":"https:\/\/voomisupply.com\/products\/osg-484-9843-square-end-mill-0-9843-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
