It features a 5\/8-inch (0.6250-inch) mill diameter, a 0.0300-inch corner radius with a tolerance of +\/-0.0010 inch, and a 2-inch length of cut. The variable helix angle runs between 42.5 and 47.5 degrees, reducing harmonic vibration during aggressive roughing passes. A ZrN (zirconium nitride) PVD coating increases surface hardness and reduces built-up edge on aluminum, brass, copper, and similar non-ferrous workpiece materials. This tool is a single-end, centercutting design intended for use in CNC machining centers and manual mills by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThe US362198 is suited for roughing operations in non-ferrous metal applications where chip evacuation and tool life are priorities. The coarse pitch, right-hand spiral flute geometry and right-hand cutting direction make it a standard choice for slotting, profiling, and peripheral milling in production and job-shop environments. It mounts in standard straight-bore toolholders with a 1\/2-inch shank bore. The 4-inch overall length accommodates moderate-depth setups without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300-inch corner radius with +\/-0.0010-inch tolerance protects the cutting edge and adds strength at the corner\u003c\/li\u003e\n\u003cli\u003eVariable helix (42.5 to 47.5 degrees) reduces chatter and improves surface finish during roughing\u003c\/li\u003e\n\u003cli\u003eZrN PVD coating extends tool life on non-ferrous metals by reducing adhesion and friction\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eLong-length series (2-inch LOC, 4-inch OAL) handles deeper pockets and walls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore cylindrical toolholders accepting a 1\/2-inch shank diameter.

Confirm shank seating depth and minimize overhang to reduce deflection on long-reach setups. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Do not exceed the toolholder manufacturer recommended axial depth of cut for the shank diameter in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +\/-0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42.5 to 47.5 degrees (variable)\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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: 0.41 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: US362198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51972017062194,"sku":"US362198","price":165.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c9c8ed5d3fb5ae7a21a9f1da388a903_190218bf-178b-46e7-a07d-c308902f4314.jpg?v=1789961087","url":"https:\/\/voomisupply.com\/products\/promax-us362198-corner-radius-end-mill-5-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
