Any one have experence with drill bits from baddogtools.com? They were shown at a woodworkers show. The salesman drilled thru concrete, steel, harden steel(a file) tile,wood and plastic all with the same bit over and over without the bit dulling or breaking. Bits have a lifetime waranty not to break or they will replace it. Looks great for the areas like the metal door jam in concrete walls. If I drill with a steel bit the second I go thru the steel and hit the concrete, my bit is toast. Just interested if anyone has tried them.
