Arbortech introduces new Head Joint blades and Heritage blades designed to offer more controlled cuts and precision for mortar removal on vertical joints and very narrow mortar joints. While the use of conventional diamond blades can easily result in over-cutting and damage to the surrounding brick work, the Arbortech Head Joint blades clean out the complete joint without any damage to surrounding bricks. The cutting depth is 3 1/8-inch deep and the cutting width is ¼-inch wide.
