AS23 is a compact angular grinde/cut of saw, the hydraulic functioning assures power, quietness, long operative life and maximum safety thanks to the implicit impossibility of causing electric shocks. For these characteristics AS23 is irreplaceable in external works with presence of water, in the maintenance of utilities networks, in metal brushing for preparation of welding , in works inside the excavation and in the UNDERWATER WORKS. Mounts standard discs with diameter 23 cm or metal brushes for scrubbing or cleaning ship hulls and propellers from marine formations. With cutting disc AS23 becomes a precise cut off saw which manoeuvrability allows complete rotation around large pipes easing the cut in narrow spaces.
