Built from micrograin carbide and finished with a TiCN (Titanium Carbonitride) coating, it delivers hardness and wear resistance suited to demanding cutting environments. The 2-flute, spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and reduces heat buildup during cuts. With a 0.25-inch cutting diameter and 1.5-inch length of cut, this end mill handles slotting, profiling, and plunge cutting. It is centercutting capable, enabling direct plunge entry without a pilot hole. Installed by machinists and CNC operators, it fits standard 0.25-inch collets and tool holders.\u003c\/p\u003e\u003cp\u003eThe 482-250008 suits general-purpose and finish milling operations on ferrous and non-ferrous metals, as well as hardened steels where TiCN coating provides a performance advantage over uncoated tooling. The extra-long 4-inch overall length allows reach into deeper pockets or fixtures where standard-length end mills cannot access. The right-hand cut and right-hand flute orientation are compatible with conventional CNC milling setups. This tool works in both horizontal and vertical milling machines, as well as machining centers running climb or conventional milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces friction during cuts\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design with 30-degree helix promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtra-long 4-inch overall length extends reach into deep pockets\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC compatibility\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of plus 0.000 \/ minus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tool for standard 0.25-inch collets, ER collet chucks, and shrink-fit holders used in CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 \/ minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: plus 0.00000 \/ minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 482\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 482-250008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735291265330,"sku":"482-250008","price":66.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82f3445b35dfe076272ad01013c41216.jpg?v=1788771535","url":"https:\/\/voomisupply.com\/products\/osg-482-250008-square-end-mill-0-25-in-solid-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
