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.

Chair repair

I used this bit to reproduce the stretchers on a 1950â€™s vintage dining room chair set. The bit cut the cherry wonderfully. This is my first experience with Woodline. The order was at my home in a few days. I would highly recommend.
