Built from solid carbide with an AlTiN coating, it delivers excellent heat resistance and tool life at elevated cutting speeds. The 4-flute, fine-pitch spiral geometry with a right-hand cut and right-hand flute direction promotes chip evacuation and reduces chatter during heavy roughing passes. At 0.75 inches in diameter with a 1.625-inch length of cut and 4-inch overall length, this tool fits standard milling chucks and Weldon flat retention setups used across production and job-shop environments. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations on ferrous and non-ferrous metals in both vertical and horizontal milling machines. The AlTiN coating makes it well matched to dry or near-dry cutting of steel, stainless, and hardened materials. The Weldon flat shank ensures positive drive retention in side-lock tool holders, which is important when taking heavy radial cuts. The 45-degree chamfer angle and 0.025-inch chamfer width help prevent edge chipping at entry. It is a solid choice for production environments running high-feed or high-speed roughing strategies where consistent tool geometry is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding roughing operations\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high heat resistance, extending tool life in dry and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute fine-pitch spiral design promotes efficient chip evacuation and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank enables positive drive in side-lock holders, preventing tool pullout under heavy loads\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer at 0.025 inches width reduces edge chipping on initial workpiece contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-inch Weldon flat side-lock tool holders on CNC and manual milling machines.

Power down and lock out the spindle before loading or unloading the tool. Seat the Weldon flat fully against the set screw before tightening to ensure proper drive engagement and prevent axial pullout. Confirm runout with an indicator after installation and before beginning cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SR420\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.77 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17004675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560817787186,"sku":"17004675","price":418.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c68c9f5c93fb891fa659df9cd307610.jpg?v=1786458175","url":"https:\/\/voomisupply.com\/products\/seco-17004675-roughing-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
