The #4 Round carbide is the most popular round cutter that Ken Brown uses to engrave glass and wine bottles. It is great for forming letters that are 1/4″ in height.
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. We carry only quality burs.
