There is provided a non-rotating, self-centering stabilizer (10). The stabilizer (10) includes a cylindrical sleeve (12) disposed about a rotating mandrel (34). A plurality of wear-resistant pads (18A, 18B and 18C) partially extend from a similar number of longitudinal channels (14A, 14B and 14C) to form a stabilizing relationship with the wall of a hole being drilled. |
