Built around the WEZ cutter style, this right-hand tool accepts two AOMT11 or AOET11 indexable inserts and delivers a 90-degree lead angle for true square-shoulder profiling. The steel body features a 5\/8-inch Weldon flat shank for positive drive in standard end mill holders, and through-coolant capability supports chip evacuation and tool life at elevated cutting speeds. The overall length is 3.218 inches, making it compact enough for close-tolerance work. This tool is suited for machinists and toolroom technicians running CNC vertical or horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThe 2900W6J is applied in square-shoulder milling, slotting, and side-milling passes where a clean 90-degree wall is required. Through-coolant delivery makes it well-suited for ferrous materials and applications where heat buildup or chip packing is a concern. The 0.394-inch maximum depth of cut and 5\/8-inch cutting diameter position this tool for finishing and semi-finishing passes in steel and similar alloys. Typical install environments include job shops, production machining cells, and maintenance toolrooms operating CNC milling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch cutting diameter with 0.394-inch maximum depth of cut for square-shoulder profiling\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle produces true perpendicular walls in milling passes\u003c\/li\u003e\n\u003cli\u003eAccepts two AOMT11 or AOET11 indexable inserts for cost-effective edge replacement\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability improves chip clearance and extends insert life\u003c\/li\u003e\n\u003cli\u003e5\/8-inch Weldon flat shank provides positive, slip-resistant drive in standard holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation; steel body construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with AOMT11 and AOET11 series indexable inserts.

Secure the Weldon flat shank firmly in a properly sized end mill holder, torquing the set screw to the holder manufacturer specification before use. Verify spindle direction is set to right-hand rotation before engaging the cut. Confirm through-coolant passages are clear and coolant flow is active before beginning cuts to prevent insert damage from heat accumulation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: WEZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.218 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: AOMT11, AOET11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2900W6J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731030868274,"sku":"2900W6J","price":299.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e644418ddbd2b7131d51780a83e1a13a.jpg?v=1788726103","url":"https:\/\/voomisupply.com\/products\/sumitomo-2900w6j-square-shoulder-end-mill-5-8-in-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
