Sorry about asking an elementary question.
I am tring to set up an end mill as tool in tooltable.  Which icon do I use for this? The one that looks like a rectangle?

Looking through the tooltable I would say it is certainly the only one that would resemble an endmill but really does it matter what icon you use? I could see it being handy for lathe tools as it would give a quick visual identification but for endmills I dont see this being a problem.

Thanks Hood.  You answerd my question.  I was not sure if the icon had any significance or not.  I am also not sure how the diameter wear and height wear parameters are used.   The wear is function of time and material used.
