Gorilla GCT-9 Silverback Dustless Electric Crack Chaser
The Gorilla GCT-9 Silverback Dustless Electric Crack Chaser is a heavy-duty electric crack chasing and joint cleanout saw designed for concrete repair, surface preparation, and dust-controlled dry cutting. Built for contractors who need a maneuverable walk-behind platform, the GCT-9 Silverback gives operators the ability to chase cracks, clean joints, and prepare concrete repairs while working from a standing position.
This machine is well suited for concrete repair crews, flooring contractors, joint-filling contractors, industrial maintenance teams, warehouse floor repair work, and indoor concrete surface-preparation jobs where dust control and operator comfort are important. The Silverback is designed with locking and swiveling rear casters so operators can lock the machine for straighter cuts or unlock it to follow irregular cracks.

Product Benefits
The GCT-9 Silverback helps improve productivity and comfort by moving crack chasing work from a handheld grinder position to a more controlled walk-behind setup. Its caster design allows the operator to adapt to the job: lock the rear casters for straight joint cleanout or unlock them to help track irregular cracks across the slab.
The electric power platform makes the machine a practical option for indoor work where combustion equipment is not ideal. When connected to a properly sized dust extractor, the dust-control design helps reduce airborne concrete dust and cleanup time, making it useful for occupied buildings, industrial facilities, and indoor floor repair projects.
The adjustable cutting depth and blade size range give contractors flexibility for different repair profiles, joint widths, and concrete preparation requirements. The compact walk-behind format also makes it easier to transport and position on jobsites compared with larger joint saws.
Ideal Applications
Concrete crack chasing
Joint cleanout
Crack preparation before repair material

Surface-preparation projects
Epoxy and polyurea repair preparation
Indoor concrete repair with dust collection
Contractor maintenance and repair work
Recommended Use
Use the Gorilla GCT-9 Silverback with an appropriately sized dust extractor that meets the machine's required airflow rating.
