'Scuse me for being nosey, but why is it necessary to remove that much

Even with a half-ton CNC router I haven't found it necessary to cut
deeper than one bit diameter at a time, and use multiple passes as needed...

...and a two-inch depth of cut will already be asking a lot of any
portable router

Thanks for all the reply's. I bought high speed end mills with a
cutting flute of 3 in. The reason I wanted it longer than 2 in., is I
use the bit in a plunge router to cut the mortise for loose tenons
when working with wide material.
