Never tried roughing end mills before so a few weeks ago I asked about these "corn cobs" and received good information*. I ordered a couple of 3/4 cutters and put them away...

Today, I needed to do some weld prep on 1/2 and 3/4 hrs plate and remembered the corn cobs. They worked VERY well. The cutting sound was different than a standard cutter and my small mill felt "bigger".

A good investment !

edited to add:

*information/recommendations for these cutters came from the forum. Thanks,

The corn cob end mill piqued my interest. What do I look for in the tool catalog to describe this end mill ? Looked in the MSC catalog and saw nothing under corn cob.

I think that they are just called "roughing end mills". I don't have an MSC catalog but this is how they are listed in the Enco book.

("Corn cob" is the popular description, it's because of the way the cutters look.)

they have a wavy cutting edge or groove cut in their diameter along the flutes.
