Kennametal 3745047 Square-shoulder Face Mill 3 in

Product Description

The KENNAMETAL 3745047 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining applications. Built around a 3-inch maximum cutting diameter and a 1-inch arbor hole, this mill accepts 8 inserts with a 0/90 lead angle for true square-shoulder cuts. The body stands 1.75 inches tall and supports a maximum depth of cut of 0.389 inches. It uses EC10 and EP10 insert styles and is part of the KENNAMETAL Mill 1-10 series. Installation is right-hand cutting direction, and the tool is intended for use in CNC machining centers and manual milling machines operated by skilled machinists.

This face mill is suited for general-purpose square-shoulder milling on ferrous and non-ferrous materials in production and job-shop environments. The coarse pitch configuration and 8-insert capacity make it appropriate for medium-to-high material removal rate applications. The 2.19-inch hub diameter provides solid arbor support for stable cuts. It is typically used in horizontal or vertical milling setups where a full 90-degree shoulder is required, such as stepping, slotting, or face milling workpiece edges. Coolant-through is not supported on this body.
