What's it for?

Concrete wall sawing, often called track sawing, is a precise construction technique using a diamond-toothed blade mounted on a track system to cut perfectly straight, smooth openings in vertical or horizontal concrete surfaces, such as walls, ceilings, and floors. It is widely used to cut precise openings for doors, windows, HVAC, and elevator shafts in reinforced concrete, brick, or stone, as well as for demolition work to remove sections of concrete.
