The round bits in the little grey container are called Hole Saws. They are basically a round saw. They cut clean round holes of various sizes. Unlike a drill bit that just bores a hole in wood or metal the hole saw actually cuts out a plug of wood or metal. the plug is released out of the hole saw after you cut the hole. I am a hobby wood worker! I do not sell anything I build as i normally just build stuff for around my house. I look forward to seeing what you build
