Ball Burs (SD)
Available107 products
Ball burs (SD) debur and finish round openings and contoured surfaces, shape bevels and concave surfaces, and enlarge bore holes. The spherical head keeps edges smooth and bur-free. Cutting edges are made from carbide, which is a hard material that resists wear and limits heat. Carbide burs attach to rotary power tools such as die grinders, high-speed engravers, and pendant drills.
Double-Cut Ball Burs
Double-cut ball burs (SD) have crossing left- and right-hand flutes to quickly remove stock from steel, stainless steel, and other high-strength ferrous metals while leaving a smoother finish than single-cut burs.
