Carbide Ball Burrs
  Use a ball or spherical shaped carbide burr to create concave cuts in your material or to shape and hollow out an area. Small carbide ball burrs from as tiny as 0.5mm in diameter are ideal for intricate carving projects. Many wood carvers, stone carvers and metal engravers use these carbide carving burrs in a hobby drill, micro motor or a high speed handpiece. As we mentioned before, make sure to use a handpiece that runs true ie with no wobble.
