KUD - Ball
The KUD shape (ball) rotary burr is the ideal tool for machining curved internal profiles and hollowing out hemispherical cavities. Its perfectly spherical geometry enables material removal in all directions with maximum control, making it perfect for engraving, finishing concave radii, and shaping complex contours without creating sharp edges.
