Need to cut some 3/16" deep x 7/16" wide tongues on some ash. I'm doing it on my router table.
Using some scrap of the same dimension as the work piece, I started with a 3/8" straight bit but it splintered the ash. Then I went to a 5/32" 3-wing cutter and got better results. My question is, should I stick with the 3-wing cutter or should I use a rabbet bit? I don't cut the full dimension of the tongue in one pass. I incrementally work to it.
Another thing, is ash that brittle for it to splinter when routing?
Thanks in advance for any assist.
