Perfectly cuts pine and hardwood edges with a V-shaped internal drill. Cut the plywood without burning it with an external V-burr but left a slightly rough edge that needed sanding so the seam line was visible after painting.

Next time, though, try a vertical edger on pine veneer plywood to get a sharper edgeβ¦
