I need help!! My brother got 2 giant drill bits, about 5 inches in diameter, the commercial bits that are used for going thousands of feet in the ground. He inserted money on each end of each bit. He then brought it to a metal place who froze the bits, then pushed them together with a 100 ton press! Then when it warmed up the metal expanded and reinforced. When I try drilling with metal drill bits, they snap. I can't heat it because the money will burn. Any ideas how I get in this impossible metal gift?
