I’ve actually thought about a Rock Boss or an ICS saw just for removing stumps/roots just below grade as an alternative to buying a stump grinder.
Stihl does make a Rock boss saw for cutting concrete. Never seen one used in person. Think it uses a 461 powerhead.
Never tried it, but my guess is that a concrete chain saw wouldn't cut wood worth a poop! Chain is drastically different
A large sail boat went aground and burned to the waterline on Anderson island near here many years ago. Some enterprising locals bid to the insurance company for the removal of the hull from the beach. They took all the charred fiberglass away with a backhoe and small dump truck at low tide and then started on the approx. 2500 lb lead keel. I assume they were using carbide chains in their chainsaws to cut the keel into manageable chunks. Lead was at a high salvage price then so they probably did pretty well. I imagine getting Manson to come in there with a tug and a barge and crane would have been unbelievably expensive.
Worked on a commercial construction job at the old Heinz plant in Pittsburgh years ago. They cut big holes in the floors for mechanical shafts. They used a concrete chainsaw. Was hydraulic powered and had the water hookup right to it also. No idea what brand saw it was, but it really tore through that floor.
Wood, or concrete floor? We had some holes cut in concrete tank walls at work back in 2015, about a foot thick and took some time, but they did a nice job...dunno of any other way it could have been done, at least not a square hole, and such a clean cut
I imagine they had to mitigate that in some fashion. Maybe with tarp drop cloths or something similar. Funny, but over the years there is probably more lead in lost sinkers on my favorite fishing reef than in that whole sailboat keel!
