    摘要： A cutting element has a sleeve with a first inner diameter and a second inner diameter, where the second inner diameter is larger than the first inner diameter and located at a lower axial position than the first inner diameter. A rotatable cutting element having an axis of rotation extending therethrough is at least partially disposed within the sleeve. The rotatable cutting element has a cutting face and a body extending axially downward from the cutting face, at least one hole extending from an outer surface of the body toward the axis of rotation, and a locking device disposed in each hole. The locking device protrudes from the hole to contact the second inner diameter of the sleeve, thereby retaining the rotatable cutting element within the sleeve.
