That will work!
I had never thought of straight vs twisted. Do you know where can I find more information on the comparisons?I'd use a straight solid carbide, not twisted. It might pull the sample off your template.
A straight has no shear vectors.
This is the bitJohn if the bit is listed as a down-cut bit it will try to lift the part off the table because it is designed to push chips away from the collet. If you do use a down-cut bit it would be best to use feather boards to hold the part down for safety.
I can trade it in with the store for a straight bit, do you thunk that would that be a safer option?John that is a down shear bit but it is not a spiral bit. It will try to push the part up from the table, remember the router is upside down in the table. The more material you try to take at one time the more pressure will be generated. If you make lite passes and use good push blocks you should be okay, just don't try to over feed the bit or it might cause enough rise you might have problems.
