Hi
I use allot of necked endmills.
For example a flute length of 22mm but with a neck of 36mm.
So you can go 36mm deep without rubbing the endmill against the part.
You can specify the "Shoulder length" in the tool setup.
But when you're in the tool library you can't sort on "shoulder length" or have a column that specifies this.
So you really need to know which tools are necked. Or keep a separate Excel sheet which specifies all tools and lengths.
