An apparatus for use on a portion of a milling or mining drum may include a base portion and a cutter bit. The cutter bit may include a tip region, a flange having a nut-like gripping surface, and a shank portion. At least a distal end of the shank portion may include a threaded portion. The shank portion may be received in an opening of the base portion. The opening of the base portion may be internally threaded to engage the threaded portion of the shank portion of the cutter bit.

A retainer may be internally threaded into the opening of the base portion and threadably engaged in the second threaded portion.
