Carbide—Best for removing material from a variety of metals. These burs are harder, stronger, and more wear resistant than high-speed steel.

Heavy Duty Double-Cut Tooth—The best option to remove material quickly. These burs have the deepest flutes with the sharpest cutting angle and offset teeth on the tip. Although they break up chips the fastest, they leave the roughest finish.

Double-Cut Tooth—Double-cut tooth burs are for rapid metal removal with a coarser finish than single cut.

Single-Cut Tooth—Single-cut tooth burs are for gradual metal removal with a fine finish.

Single-Cut Tooth with Chip Breaker—Remove material fast with a fine finish. These burs cut like double-cut tools but leave a single-cut finish. They have single-cut teeth divided by diagonal rows of chip breakers. The chip breakers tackle your roughing work and reduce the pressure needed to cut, while the single-cut teeth create a smooth surface.
