A drill bit includes cutters rotatively mounted thereon. A bore is provided either directly in the drill bit or in a sleeve which is mounted on the drill bit. The bore includes a female screw thread, a circumferential groove, and one or more bearing surfaces. A cutter with a hardened table has a generally cylindrical body with a male screw thread, a circumferential groove, and one or more bearing surfaces. The cutter is engaged with the threads of the bore and then advanced until the male screw threads pass beyond the female screw threads. When the cutter is fully installed, the circumferential grooves provide relief for the screw threads so that the cutter can freely rotate within the bore.
