Built on the WaveMill platform, this toolholder uses a WEX cutter style with a 90-degree lead angle, delivering true square-shoulder cuts in a single pass. The 3\/4 inch cutting diameter pairs with a 3\/4 inch Weldon flat shank for secure, anti-rotation clamping in standard end mill holders. Through-coolant capability directs fluid directly to the cutting zone, helping manage heat and chip evacuation during aggressive material removal. Inserts are screw-held using the AX.T 12350 insert style and the tool accepts 3 inserts. Overall length is 4.091 inches, with a shank length of 2.031 inches and a head length of 2.060 inches.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on universal workpiece material classifications including ISO material codes K, M, N, P, and S, covering cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. It is typically used in vertical and horizontal machining centers where a rigid, indexable square-shoulder tool is required. The Weldon shank design is common in production environments where pullout resistance under heavy side loads is a priority. The ISO designation for this toolholder is WEX20750EMW.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n\u003cli\u003eWEX cutter style with Weldon flat shank for anti-rotation grip\u003c\/li\u003e\n\u003cli\u003eAccepts AX.T 12350 insert style, screw-held, 3 inserts total\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO material codes K, M, N, P, and S (universal application)\u003c\/li\u003e\n\u003cli\u003eCompact 4.091 inch overall length for use in tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eUses AX.T 12350 insert style.

Secure the Weldon flat shank fully into a matched end mill holder and torque the set screw per the machine tool manufacturer's specification. Before inserting or replacing cutting inserts, ensure the machine is powered down and in a locked-out state. Confirm through-coolant passages are clear and that the coolant supply pressure is within the machine tool's rated range before beginning operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.091 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: WEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: AX.T 12350\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WaveMill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: WEX20750EMW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 2900W2R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730070798642,"sku":"2900W2R","price":368.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a49210fd5c7e8af39bb2fa91160575d_154e1827-0b7a-48a1-b588-813072e2fa3a.jpg?v=1788711201","url":"https:\/\/voomisupply.com\/products\/sumitomo-2900w2r-indexable-square-shoulder-end-mill-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
