Built around the MILL 4-15 series platform, it features a 1-inch cutting diameter and accepts LNGU15T608SRGE insert style inserts secured by a screw-holding method. The toolholder designation is M4D100L1502W100L175. With a 0-degree lead angle, this end mill produces true 90-degree shoulder walls, making it well-suited for face milling, slotting, and shoulder milling where a square step profile is required. Licensed machinists and CNC operators in production shops and tool rooms are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for use on CNC machining centers and manual mills in both production and job-shop environments. The Weldon flat shank provides a positive mechanical engagement with the spindle, reducing pull-out risk during aggressive cuts. With a maximum depth of cut of 15.5 mm (0.61 inches) and an overall length of 4.03 inches, it fits standard tool-change systems and short-reach spindle configurations. It carries 2 insert pockets, supporting balanced cutting forces at moderate to high feed rates in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch cutting diameter with 0-degree lead angle for true square-shoulder profiles\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 15.5 mm (0.61 inches)\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive mechanical retention in the spindle\u003c\/li\u003e\n\u003cli\u003eAccepts LNGU15T608SRGE insert style, secured by screw-holding method\u003c\/li\u003e\n\u003cli\u003e2-insert pocket design supports balanced cutting forces\u003c\/li\u003e\n\u003cli\u003ePart of the MILL 4-15 series platform for consistent insert availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with LNGU15T608SRGE series inserts.

Ensure the machine spindle is fully stopped and the tool-change program is in a safe state before mounting or removing the toolholder. Torque the Weldon set screw against the flat per your shop standard to prevent axial pull-out. Inspect insert seats and seating surfaces for chips or damage before seating new inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.5 mm (0.61 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Insert Pockets\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNGU15T608SRGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MILL 4-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: M4D100L1502W100L175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10 inches L x 12.6 inches W x 2.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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: 5544366\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731678003506,"sku":"5544366","price":500.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2b58c9cbb185f0fc2d78057b9a6e7c1.jpg?v=1788733806","url":"https:\/\/voomisupply.com\/products\/kennametal-5544366-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
