Round cutters can be used to engrave metal, wood, eggs, glass and any other surface. For example, Ken Brown uses round carbides to create beautiful calligraphy letters on wine bottles. Joe Cummings uses round carbides to carve intricate designs into gun stocks. There is no right or wrong way to use a round carbide as long as you get the result you’re looking for. When it comes to carbide burs, there is a difference. Inferior burs will wear very quickly. Some won’t even be round (when they say they are). The heads might POP off some. We carry only quality burs.
