It features a 3\/4 inch shank diameter, a 0.25 inch mill diameter, and a 1 inch length of cut, giving machinists precise control over chip evacuation and surface finish in long-reach setups. The ZrN (zirconium nitride) PVD coating reduces friction and heat buildup, extending tool life in aluminum, copper, brass, and similar workpiece materials. With 3 flutes, a variable helix, and a coarse pitch, the US362290 is optimized for roughing operations where aggressive stock removal and vibration damping are priorities.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where toolholder-mounted, straight-cylindrical shank tooling is standard. The single-end design with a right-hand flute direction and right-hand cutting direction suits conventional horizontal and vertical mill setups. It is rated for non-ferrous metal workpiece materials and carries a material grade of micrograin carbide, making it well-suited for precision shops running production runs or prototype work in aluminum and other soft alloys. The long flute type classification supports deep-pocket and slotting work where extended reach is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eZrN PVD coating reduces friction and extends tool life in aluminum and copper alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix design dampens vibration during roughing passes\u003c\/li\u003e\n\u003cli\u003eCoarse pitch geometry promotes efficient chip evacuation in high-MRR operations\u003c\/li\u003e\n\u003cli\u003eCorner radius end type protects cutting edge at entry and reduces stress concentration\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 3\/4 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the end mill. Secure the shank in a compatible toolholder to the holder manufacturer's specified torque; do not over-tighten collet nuts by feel alone. Verify runout with a dial indicator before beginning a production cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0015 to 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0040 inches\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\u003c\/strong\u003e: ZrN (PVD)\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eSeries\u003c\/strong\u003e: US362\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: US362290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51997606740274,"sku":"US362290","price":198.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c9c8ed5d3fb5ae7a21a9f1da388a903_799aa37f-f2ab-414a-87bf-e95ed98fda68.jpg?v=1789994239","url":"https:\/\/voomisupply.com\/products\/promax-us362290-corner-radius-end-mill-3-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
