The wall saw is a rail-guided unit, which is driven either hydraulically or recently with high-frequency electric motors. Cutting depths of up to 90cm can be achieved with the diamond-tipped cutting blades. Their field of application is diverse, which is why they are used almost everywhere where an exact cut is emphasized. Rectangular wall and ceiling openings can be easily created with it. Classically used when dismantling balconies or entire balcony systems.
