Technical guidance & FAQs

Applications and materials

WIDIA WCE4 W401 inch square-end mills combine four flutes with a straight cylindrical shank. The square-end geometry supports shoulders, slots and pockets requiring that end form rather than a specified corner radius. WCE4 uses asymmetrical indexing and variable helix for versatile metal milling.

Choosing a configuration

Compare cutting diameter, cutting depth and overall length for the exact W401 tool. Match the straight cylindrical shank to the holder and keep inch ordering numbers separate from the other unit system.

Compatibility and use

Use WCE4 guidance for the actual workpiece and operation; the platform’s primary applications include steel, stainless steel and cast iron. Confirm the selected straight cylindrical shank fits the holder and that the square end geometry meets the component drawing.

When should I choose the square-end version?

Choose it when the shoulder, slot or pocket requires that end form. Radiused and chamfered versions change the outside cutting corner.

How do I compare W401 with another WCE4 length series?

Compare actual cutting depth and overall length at the required diameter. Keep the square end form and straight cylindrical shank consistent when checking a replacement.

Can a similar inch or metric tool be substituted?

Check exact cutting and shank dimensions, end form and required length. This listing uses inch configurations; a converted nominal diameter does not establish an equivalent ordering number.
