Angle Head

A drywall angle head (or corner finisher) is an automatic taping tool used by professionals to apply joint compound (mud) and create smooth, perfectly feathered finishes on inside corners (wall-to-wall or wall-to-ceiling) in a single pass, collecting excess mud and reducing hand-finishing work. It attaches to a handle and glides along the corner, using precision blades and spring-loaded wings to feather the mud edges for a seamless look, making it much faster and less strenuous than manual methods.
