Works with
Runs as a system with a Lavina propane dust extractor in the V20GE or V25GE class, which keeps silica out of the air while you grind. The quick-change plates carry Latux metal-bond and PCD tooling, so one machine can go from aggressive coating removal to a polished finish.
Shop the setup
Does it need electrical power?
No. The 20G S7 runs on a propane Kawasaki FS481V engine, so it works on outdoor and remote slabs with no shore power and no generator.
How much grinding pressure does it apply?
Four weight positions set 286 to 363 pounds of down pressure, so you can run light for polishing or heavy for coating and glue removal.
What dust extractor should I pair with it?
A Lavina propane dust extractor in the V20GE or V25GE class keeps up with the 20 inch head and captures the silica this machine produces.
What tooling does it take?
Lavina quick-change plates. Latux stocks matching metal-bond and PCD segments for every step from grinding to polishing.
How do I buy it, and what about freight?
