A ring saw is a type of hand held saw. This method is used to cut into all types of building materials up to 265 mm deep. It uses a diamond tipped offset cutting wheel, which is powered by hydraulics or electricity. They are most often used when either wall saws are not effective or there is not enough room for a wall saw to fit well.
In addition to being able to fit into areas with restricted access or close quarters, it also produces a clean cut while being low-noise and vibration free. The ring saw rotates on a roller system and does not have a core or centre, unlike other handsaws that do have a centre and are rotated on a spindle.Using this handsaw method is good for wall, door and window openings, concrete pipes and manhole covers and more.
