AS 23
HYDRAULIC GRINDER
Angular grinder/ cut off saw for use on land and
underwater , the hydraulic functioning assures
power, quietness, low vibrations, long operative life
and maximum safety thanks to the implicit
impossibility of electric shocks. For these
characteristics AS23 is irreplaceable in external
works with high presence of water, in the
maintenance of utilities networks, in metal
brushing for preparation of welding , in works
inside trenches and in the underwater works.
Mounts standard discs with diameter 230mm
(capacity 9”) or metal brushes for scrubbing or
cleaning ship hulls and propellers. With cutting
disc AS23 becomes a precise cut off saw which
manoeuvrability allows complete rotation around
large pipes easing the cut in narrow spaces.
Powerful , compact and safe the tool is for
characteristics and function irreplaceable in many
applications where traditional electric tools cannot

ADVANTAGES

- The underwater model AS23UW has hydraulic characteristics and disc speed
different from the land model
- The exclusive hydraulic “orbital” motor fabricated by DOA generates higher revolution
per minute and mantains high torque and speed even with high load on disc
- Oversized shaft and ball bearings assure robustness and long operative life
- Unbeatable power/weight/dimension ratio , real minimal maintenance needed
