Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance at cutting speeds that would wear down standard HSS tooling. The cutter measures 1\/4 inch (0.2500 inches) in diameter with a 0.0750-inch corner radius and runs three straight flutes in a right-hand cutting, right-hand flute direction. Overall length is 2.5 inches with a 1\/4-inch cylindrical shank. The double-end configuration extends tool life between regrinds or replacements. Machinists and tool-and-die professionals specify this geometry for consistent, repeatable corner breaks on finished parts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium — covering ISO material groups P, M, K, N, and S. It is a strong fit for job shops, production floors, and toolrooms where multiple work materials cycle through the same setup. The micrograin carbide substrate and AlTiN coating support dry cutting and high-speed machining passes without sacrificing edge integrity. The tip diameter of 0.0900 inches allows access to tighter part features while maintaining the 0.0750-inch radius profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating provides high heat resistance and extended tool life across ferrous and exotic materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports sharper edges and tighter tolerances than standard carbide grades\u003c\/li\u003e\n\u003cli\u003eDouble-end design doubles the number of available cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e3-flute, straight-flute geometry balances chip evacuation with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix compatible with standard CNC and manual milling setups\u003c\/li\u003e\n\u003cli\u003eCylindrical shank fits standard collets and end mill holders without special tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit corner rounding end mill for 1\/4-inch collet and end mill holder systems used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully in the collet or holder and torque the drawbar or clamping nut according to the machine manufacturer's specifications. Inspect the cutting edges for chips or coating damage before each use, and verify runout with a dial indicator after initial setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.0900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Super Alloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68-1290-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690583163186,"sku":"68-1290-C","price":111.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ff0c2b29c16096ef5c476252050d76b.jpg?v=1788272096","url":"https:\/\/voomisupply.com\/products\/value-collection-68-1290-c-corner-rounding-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
