Abstract
A boring tool has a cylindrical body (1) with cutter blades (7) slidable at an angle to the body axis. The projection of the blades beyond the body and thus the boring diameter is set by a rotatable advancing member (12) having a conical head (11) to engage the blades and a threaded shank (13) within a threaded portion (14) in the body. Rotation of the member (12) is produced by rotation of a worn (17) engaging a worm wheel (16) fast to the shank.
