We protect our locks and locking mechanisms withhardplate lock guards. These strong plates of hardened steel are great at thwarting drill attacks because they quickly chew up, snap or spin the drill bit.
Multiple layers of hardplate will chew up a drill bit quickly as it continues to shake, trying to get through the steel’s hard surface.
Ball-bearing hardplate is even tougher on a burglar’s drill bit. Numerous ball-bearings are encased into a piece of hardplate. When the crook tries to drill into your lock, either his drill bit is going to snap, or it will keep spinning on those tiny steel bearings forever.
