Double cut burs are cross cut and ideal for machining cast iron, steel, stainless steel (INOX), nickel-based alloys, and titanium alloys. These burs have a high stock removal rate. Universal line burs are designed for fine and coarse stock removal on the key materials used in industrial manufacturing. They provide a good stock removal rate and are not specific to a particular material. Cylindrical bur Tungsten carbide burs with extended shanks are ideal for efficiently machining small, hard-to-reach areas. The shanks can be shortened if required. This bur has a long steel shank.
