That's not a woodworking drill press. It's a stand that attaches to concrete for wet core boring. The post is set up backwards, the drill would go on the opposite side they show. Four shields are drilled into the concrete and the stand is bolted to the wall or floor. An 8" or longer diamond core bit, like a deep hole saw, is driven by a 1/2" drill and can drill completely through a foundation wall, bulkhead on heavy construction, like bridges, etc. Inexpensive ones are $250 or more, many are closer to $500. At $100, it's a deal but it's a specific use tool and many folks wouldn't know what it's for.
