Technical guidance & FAQs

Applications and materials

WIDIA WCE4 W411 inch corner radius end mills combine four flutes with a Weldon shank. The specified outside-corner radius supports milling features that require a rounded transition rather than a sharp tool corner. WCE4 uses asymmetrical indexing and variable helix for versatile metal milling.

Choosing a configuration

Compare cutting diameter, corner radius, cutting depth and overall length for the exact W411 tool. Match the Weldon 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 Weldon shank fits the holder and that the corner radius geometry meets the component drawing.

Is a corner-radius end mill the same as a ball nose?

No. A corner-radius tool rounds the outside corner while retaining an end face; a ball nose has a full rounded end profile.

How do I compare W411 with another WCE4 length series?

Compare actual cutting depth and overall length at the required diameter. Keep the corner radius form and Weldon 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.
