Walter 5205207 Indexable Square-shoulder End Mill 1 in

Product Description

The WALTER 5205207 is an indexable square-shoulder end mill designed for 90-degree shoulder milling operations in metal cutting applications. It accepts two AD.T 1606.. series inserts and delivers a 1-inch (25.40 mm) cutting diameter with a maximum depth of cut of 0.591 inches (15 mm). The overall length is 3.871 inches, and the tool mounts via a 1-inch Weldon Flat shank for secure, anti-rotation clamping in milling chucks and holders. This cutter is installed and operated by machinists and tool-and-die professionals working on CNC or manual milling machines.

This end mill is suited for square-shoulder profiling, slotting, and step milling on ferrous and non-ferrous materials. The 90-degree lead angle produces a true square shoulder, making it appropriate for workpiece features that require perpendicular walls. The ISO designation for this cutter body is F4042.UW26.026.Z02.15, confirming its place in the F4042 cutter style family. It meets both ISO and ANSI standards, making it applicable across a wide range of shop environments.
