It features a 1\/4 inch cutting diameter, a 3\/4 inch length of cut, and a 0.02 inch corner radius that reduces stress concentration at the tool tip and extends tool life on hardened and abrasive materials. The 4-flute, single-end design with a right-hand spiral flute and medium 30-degree helix is optimized for both roughing and finishing passes. A straight-cylindrical 1\/4 inch shank fits standard toolholders. Licensed machinists and CNC operators install this tool in milling centers for general metal removal work.\u003c\/p\u003e\n\u003cp\u003eThe 496-2502 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, and hard materials. With a 2.5 inch overall length and regular-length flute geometry, it fits typical toolholder setups in vertical and horizontal machining centers. The uncoated bright finish makes it straightforward to inspect for wear and is appropriate for applications where coating buildup on the workpiece is a concern or where cutting fluid is applied directly. The centercutting capability allows plunge entry into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02 inch corner radius reduces edge chipping and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eMedium 30-degree helix angle balances chip evacuation and cutting force across multiple material types\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows direct inspection of tool wear and suits flood coolant environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 1\/4 inch cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm shank seating depth and holder clamping to manufacturer specifications before engaging the cut. Follow all applicable shop safety protocols and machine tool manufacturer guidelines for speed and feed selection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (1.0000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 496\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 496-2502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752964686130,"sku":"496-2502","price":43.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/399b384154093aacd4fe29e8e5c808d1_ceaa6570-137d-4de4-9a0b-f5f1fd911d30.jpg?v=1788931610","url":"https:\/\/voomisupply.com\/products\/osg-496-2502-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
