Yeah Bud I've heard about a year ago, then I've seen them at Home Depot briefly, that's the name of company or product and they make several different styles for different needs . I saw one with maybe carbide flaps sorta like the flap sanding discs, it looked a little non durable, I would have liked to see the entire line of products in front of me so I could decipher what would be good for any situation I may need to get out of fast and the end result needed.
There's certainly a void in floor prep equipment that those products will fill, after that it's high dollar, makes me want to punch a hole in drywall, using a studfinder first takes away the spontaneity.
