Built around ISO number 125ED10W125Z3L210C15, this tool features a 1-1\/4 inch cutting diameter and accepts up to 15 EC10 or EP10 series indexable inserts secured by screw clamping. With a maximum depth of cut of 1.764 inches and an overall length of 4.371 inches, it handles demanding shoulder milling, slotting, and helical interpolation applications. Installation and setup are performed by machinists and tooling specialists in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop environments where square-shoulder profiling, pocketing, and helical ramping are required. The Weldon flat shank measures 1-1\/4 inches in diameter, providing secure, anti-pullout seating in standard end mill holders. With a lead angle of 0 degrees, it produces true 90-degree walls on workpiece shoulders. The 3-flute, 15-insert configuration supports aggressive material removal rates at spindle speeds up to 29,400 RPM, making it appropriate for aluminum, steel, and cast iron applications depending on the insert grade selected.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch cutting diameter with 1.764 inches maximum depth of cut for deep shoulder passes\u003c\/li\u003e\n\u003cli\u003eAccepts EC10 and EP10 series indexable inserts with screw-lock clamping\u003c\/li\u003e\n\u003cli\u003e3-flute body carrying 15 inserts for high feed and material removal efficiency\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank design minimizes tool pullout during heavy cuts\u003c\/li\u003e\n\u003cli\u003e0-degree lead angle produces precise 90-degree square shoulders\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 29,400 RPM compatible with high-speed machining centers\u003c\/li\u003e\n\u003cli\u003eHelical tool application supports ramping and circular interpolation entry strategies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with EC10 and EP10 series indexable inserts.

Ensure the machine spindle is fully powered down and locked out before mounting or removing the tool body. Seat the Weldon flat shank fully into the holder and tighten the set screw to the holder manufacturer's specification before running. Inspect each insert seat and clamping screw for damage before loading new inserts; replace any worn or cracked inserts before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.764 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.371 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.09 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: EC10, EP10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 29,400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: Mill 1-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 125ED10W125Z3L210C15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.6 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3746099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734689481010,"sku":"3746099","price":1582.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/519e93b5dc1448e75d4e146299b2c986.jpg?v=1788764923","url":"https:\/\/voomisupply.com\/products\/kennametal-3746099-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
