Abstract
A stuck drill bit having a KCS shank can be removed using an article with a body structure. The body structure has an opening that fits onto the shank, and an inward-facing surface around the opening is at least partially complementary to the surface of the shank. The surfaces engage sufficiently that rotary manual force is transferred from the inward-facing surface to the surface of the shank.
