A plugging chisel is a hand tool designed for removing mortar from between bricks or stones, typically in preparation for repointing work. With its narrow, flat cutting edge, the plugging chisel allows for precise control when raking out joints without damaging surrounding masonry—making it an essential tool for conservation stonework, brick restoration, and heritage repointing.
Unlike general-purpose chisels, a plugging chisel is engineered to fit neatly into mortar joints, allowing you to cleanly cut and remove old, loose, or damaged lime or cement mortars in a controlled, careful manner.
