Kennametal 2623857 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2623857 is an indexable square-shoulder end mill designed for precision milling operations in metal cutting applications. It features a 1-inch cutting diameter, a 0.58-inch maximum depth of cut, and a 1-inch Weldon flat shank for secure toolholder engagement. With 2 flute positions and a 0-degree lead angle, this end mill produces true 90-degree shoulders on workpiece walls. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting extended insert life and chip evacuation at high feed rates. This tool is installed and operated by machinists and CNC tooling professionals in shop and production environments.

This end mill is suited for square-shoulder milling, slotting, and peripheral milling in ferrous and non-ferrous materials. The Weldon flat shank seats securely in compatible Mill 1 toolholders, minimizing pullout under aggressive cutting conditions. The 4.03-inch overall length and 1.75-inch head length make it a practical choice for general-purpose CNC machining centers and manual milling machines where a 1-inch bore toolholder is available. Compatible inserts in the EC14.. and EP14.. series allow flexibility in selecting edge geometry and coating for specific workpiece materials.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Confirm the spindle is fully stopped and the machine is locked out before mounting or removing the end mill. Verify insert seating and screw torque before initiating a cut. Ensure the through-coolant supply pressure and flow rate meet the machine tool and toolholder requirements before operation.
