Built from solid carbide and finished with an AlTiN (WS15PE) coating, this tool delivers heat resistance and edge retention when cutting steel, stainless steel, high-temperature alloys, and hardened materials. It features a 1-1\/4 inch diameter, 5-flute geometry, and a 38-degree right-hand helix that promotes efficient chip evacuation and smooth cutting action. The 5-inch length of cut and 8-inch overall length make it well suited for deep-pocket and extended-reach milling applications in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC milling machines and machining centers where rigid setups and high material removal rates are required. The 5-flute configuration increases feed rates relative to standard 4-flute designs, making it efficient on steel and stainless steel workpieces. The Weldon flat shank provides positive tool retention in standard end mill holders. It is center-cutting, allowing for direct plunge entry. This tool is appropriate for use by machinists and CNC operators working in aerospace, precision manufacturing, and general metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating (WS15PE grade) provides elevated heat resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e5-flute design supports higher feed rates compared to 4-flute equivalents on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e38-degree right-hand helical flutes promote efficient chip flow and reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures positive retention and minimizes tool pullout in end mill holders\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC milling machines and machining centers accepting a 1-1\/4 inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the tool. Seat the Weldon flat shank securely in a compatible end mill holder and tighten the set screw against the flat to prevent axial pullout. Confirm runout and tool projection before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (WS15PE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, High-Temp Alloy, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5V0E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.46 inches L x 1.57 inches W x 1.57 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.229 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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6146621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67906295038258,"sku":"6146621","price":1589.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5a8e2485cd533a2962cfbf2e9a10e07.jpg?v=1791167040","url":"https:\/\/voomisupply.com\/products\/widia-6146621-square-end-mill-1-1-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
