"Belly Buster" Hand-Crank Audio Drill

Artifact Details

A drill with a hand crank, surrounded by drill bits and other parts

The flat, compact kit was easy for operators to conceal in transit. During use, the operator had to hold it against their stomach, earning the hand-crank drill its nickname “Belly Buster.”

CIA used the “Belly Buster” drill during the late 1950s and early 1960s to drill holes into masonry for implanting audio devices. After assembly, the base of the drill was held firmly against the stomach while the handle was cranked manually. This kit came with several drill bits and accessories.
