It features a 1\/2 inch cutting diameter and a 5\/8 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in a range of ferrous and non-ferrous materials. The variable helix angle of 46\/48 degrees and variable index geometry reduce harmonic vibration during aggressive cuts, improving surface finish and tool life. A zirconium nitride (ZrN) coating adds wear resistance and lubricity. This tool is installed and used by machinists and tool-and-die professionals in CNC machining centers and manual milling setups.\u003c\/p\u003e\n\u003cp\u003eThe US362122 fits standard 1\/2 inch straight-cylindrical tool holders and collets. It is a single-end, right-hand cut, right-hand flute design with a straight cylindrical shank. The 3-flute configuration balances chip evacuation with cutting edge strength, making it a practical choice for finishing passes or moderate material removal rates in steel, aluminum, and similar machinable materials. The tool is rated as center-cutting, allowing plunge entry where required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable 46\/48 degree helix with variable index geometry reduces chatter and vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eZrN (zirconium nitride) coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction provides rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance and cutting edge contact for finishing and light roughing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2 inch straight-cylindrical collets and end mill holders.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Tighten the collet or end mill holder to the tool holder manufacturer's specified procedure using appropriate wrenches. Verify runout with a dial indicator after clamping to confirm proper seating before beginning 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\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 46\/48 degrees (Variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\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: 0.26 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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: US362122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52123755970866,"sku":"US362122","price":106.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/779b956a124b46d3eb42ddde21ff4d99_ae1efcda-2311-40ea-96f9-00e543cbba6f.jpg?v=1790086349","url":"https:\/\/voomisupply.com\/products\/promax-us362122-square-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
