Our FS20 flush cut concrete saw uses hydraulic driven power to maintain constant cutting speeds and torque without belts, pulleys, excessive noise or exhaust fumes. Because the FS20 operates in a closed hydraulic system it is virtually maintenance free.

With this hydraulic circular saw, it is possible to cut flush with a perpendicular surface making it ideal for wall corner cuts. What’s more, our upright saw attachment allows for easy handle control when wall cutting at floor level. This setup is also the right choice for curb cutting.

The FS20 safely cuts a variety of materials in confined spaces, damp environments and underwater without risk of fumes or shock. Operate this flush cut power saw from one of our hydraulic power packs or another compatible auxiliary power source with the addition of a flow divider.
