concave cutter

Hello, Can we use a rotary tool instead of a concave cutter for cutting thick trunks? Is there anybody in this group who does like that? Thanks, brp7

Hi everyone. I have a small 7" / 180mm narrow concave cutter (like this) that I use to remove branches on small trees. For removing stubs after a straight edge concave cutter, I usually use a large 8" / 205mm spherical concave cutter, but it's inconvenient as hell when the tree is small, too...
