Thumbnail or fingernail bits, also known as half radius bullnose bits or convex edge, are used to soften hard edges on tables, countertops, stairs, and in almost all applications where you could use a full radius bullnose. These bits produce a very nice edge when the bead opening is smaller than the material thickness. Carbide tipped.

QUESTIONS & ANSWERS
Ask a Question-
Do you still sell the WL-1092 thumbnail router bit? It was recommended in an article for making a soft pillowing profile on splines for Greene & Greene style furniture. If you don't have it anymore, do you sell one with the same radius?
Currently we are not making the WL-1092 but we have WL-1097 in 1/2" shank.
