The Diamond F Ball Shape Burs are engineered for smooth contouring, hollowing, and detailed sculpting on hard materials like glass, ceramics, gemstones, bone, and hardwoods. Featuring a spherical tip with galvanically bonded diamond grit, these burs excel in creating rounded grooves, concave surfaces, and intricate 3D designs with precision.
