Built from micrograin carbide, it delivers the rigidity and edge retention needed for ferrous and non-ferrous metal cutting. The 4-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. At 4 inches overall length with a 1.5-inch length of cut, this is an extra-long configuration suited to applications requiring reach beyond standard tooling. The centercutting design allows plunge entry. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill fits machining centers, CNC knee mills, and manual mills where a 0.25-inch shank is accepted. The extra-long overall length makes it appropriate for deep-pocket milling, stepped features, and applications where clearance between the spindle and workpiece is limited. It is sold as a single unit and is well suited for machine shops, toolrooms, and production environments running aluminum, steel, brass, and similar materials. The uncoated finish keeps regrinding straightforward.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for high rigidity and extended edge life\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtra-long 4-inch OAL with 1.5-inch length of cut for deep-pocket reach\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows straightforward regrinding and reconditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any milling machine or machining center equipped with a 0.25-inch collet, end mill holder, or compatible toolholder accepting a 0.25-inch shank diameter.

Seat the shank fully into the holder to the recommended engagement depth before torquing the set screw or collet nut. Inspect the cutting edges and shank for chips or runout before use. Follow the machine manufacturer and tooling guidelines for speeds, feeds, and depth of cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 484\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 484-2500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730036162866,"sku":"484-2500","price":60.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/111e060c74eba159cf8e37e06245d316.jpg?v=1788710562","url":"https:\/\/voomisupply.com\/products\/osg-484-2500-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
