The Joint Zone AS23 is a compact angular grinder / cut off saw with high-torque and great reliability.

The AS23 is irreplaceable in difficult environments both topside and underwater, for the maintenance of utility networks, and metal brushing for preparation of welding.

Mounts standard discs with 9” diameter (230mm) or metal brushes for scrubbing or cleaning ship hulls and propellers from marine formations.

With a cutting disc, the AS23 becomes a precise cut off saw whose light weight and maneuverability allows complete rotation around large pipes easing the cut in narrow spaces.
