Built to the ISO designation M1D050E1001C062L350, it features a 0.500 inch cutting diameter and a maximum depth of cut of 0.404 inches. The 5\/8 inch cylindrical shank provides a secure fit in standard toolholders. With a single flute and one indexable insert secured by a screw-type holding method, this end mill is suited for high-speed squaring, slotting, and shoulder milling applications. Through-coolant capability is standard, supporting longer tool life and chip evacuation at high spindle speeds. Machinists and CNC operators in production and job-shop environments are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills where clean 90-degree shoulder profiles are required. The 0 degree lead angle ensures true square-shoulder cuts in ferrous and non-ferrous materials. The through-coolant design makes it effective in deep-reach or high-feed applications where heat and chip buildup are concerns. At a maximum rated speed of 56,500 RPM, it is appropriate for high-speed machining setups. The 3-1\/2 inch overall length gives adequate reach while maintaining rigidity in the cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.500 inch cutting diameter with 0.404 inch maximum depth of cut for square-shoulder milling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant with 0.118 inch coolant hole diameter for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003eSingle indexable insert (EC10.. or EP10.. series) secured by screw-type holding method\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 56,500 RPM suitable for high-speed machining centers\u003c\/li\u003e\n\u003cli\u003e5\/8 inch cylindrical shank fits standard toolholder collets and end mill holders\u003c\/li\u003e\n\u003cli\u003e0 degree lead angle delivers true 90-degree shoulder profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with EC10.. and EP10.. series indexable inserts.

Ensure the cylindrical shank is fully seated and clamped to the toolholder manufacturer's specified retention method before operation. When replacing the indexable insert, use the appropriate torx or hex key driver and follow the insert manufacturer's seating procedure to avoid insert rocking or improper clamping. Verify coolant passages are clear and aligned before resuming through-coolant operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.404 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.500 inches\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 Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 1\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: 56,500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: M1D050E1001C062L350\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: Mill 1-10\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: 3742518\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748223222066,"sku":"3742518","price":529.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49ffdf1cbfc9d2dd1daffb589177d45c.jpg?v=1788890605","url":"https:\/\/voomisupply.com\/products\/kennametal-3742518-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
