I was building a dollhouse staircase and needed a smooth, rounded edge on each tiny step. This bit cut through the pine without any burning, and the thumbnail profile left a perfect, consistent curve every time.

It made short work of softening the edges on a batch of tiny dollhouse logs I'm prepping for my niece, and the 1/2" shank barely vibrated even at full speed.

Took a plain 3/4” square piece of scrap and turned it into a mini log cabin wall in about ten minutes—the thumbnail profile cuts clean and leaves a smooth, rounded edge. It’s my new favorite for dollhouse trim, and it handled the table edge test without any chatter.
