It features a 1\/4 inch cutting diameter, a 0.03 inch corner radius, and 4 flutes with a 30-degree helix angle. The micrograin carbide substrate is coated with TiAlN via a PVD process, providing high heat resistance and extended tool life when cutting ferrous and hard materials. This is a single-end, centercutting tool, meaning it can plunge as well as profile. Machinists and toolroom operators use this end mill for both roughing and finishing passes in one setup.\u003c\/p\u003e\u003cp\u003eThe 496-250311 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, and hard materials in job shop and production environments. With a 3\/4 inch length of cut and a 2-1\/2 inch overall length, it fits standard toolholders with a straight cylindrical shank. The corner radius geometry reduces edge chipping and improves surface finish at part corners compared to sharp-corner end mills. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC vertical mill and machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentrations and edge chipping at workpiece corners\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows both plunge and peripheral milling operations\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard ER collets and milling toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore milling toolholders and ER-style collet chucks accepting a 1\/4 inch shank diameter.

Ensure the machine spindle is fully stopped and the tool changer or quill is locked before inserting or removing the end mill from the toolholder. Verify collet bore and tool shank are clean and free of chips before seating. Confirm runout with a dial indicator after clamping, as excessive runout accelerates wear on a tool of this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 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: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\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 \/ -0.0020 inches\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: 0.1 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: 496-250311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748536418610,"sku":"496-250311","price":55.62,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/osg-496-250311-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
