摘要： An anchor device (4) adapted to be anchored in an annular cavity (18) is disclosed. The anchor device comprises a body portion (6) and a cutting portion (12) and is adapted to engage a body member (24) to form a drilling assembly (2). The drilling assembly is adapted to cause the cutting portion to form an annular cavity defining a second radially inner surface (20) spaced from a first radially inner surface (30) and a second radially outer surface (22) spaced from a first radially outer surface (8). The drilling assembly defines at least one fluid delivery channel (26) for delivering fluid to a region adjacent the cutting portion to remove drill cuttings from the region via a space (40) between the first radially outer surface and the second radially outer surface. The anchor device is adapted to disengage the body member after formation of the annular cavity.
