A crew on a high-rise renovation site has to punch a new elevator shaft opening through 14-inch reinforced concrete, and they've got maybe one floor per day to stay on schedule—this is the kind of machine they bring in for that.
You choose between the three blade diameters depending on the actual wall thickness, really, so if you're mainly knocking through standdard residential brick you might stick with the 800mm, but for the 400mm or 500mm depths you'll want the 1000mm or 1200mm—the motor runs at 6150W at 3600 rpm, and that saw basically moves at about 3 to 6 meters per hour through the hardest stone you feed it.
The 220V and 380V options are wired internally, so just let us know which voltge works for your local grid layout, and along those rails (which come as two 1.2-meter sections) you get straight cuts both vertical and horizontal.
What it does is use water cooling during operation—that keeps the diamond blade from burning up and controls the dust—though we usually have stock on the base unit, I'd confirm lead time if you're ordering the 1200mm model since that one moves slower anyway.
Look, the noise hits about 85dB give or take, and with the overload protection and emergency stop it's pretty comfortable from a safety side, but humidity ceiling of 90 percent means you really don't want this sitting in damp storage for longer than a month or so.
A 24-hour order and a pallet of five machines or so gets you the better price anyway, and on the box you get a one-year warranty, the CE and ISO9001 certifcates, and teh occasional buyer will tell you it's actually better than some cheaper saws for this heavy-wall demolition, but for light framing or wood it's way too much machine.
