Split lathe toolholder bushings (sometimes called B bushings) fit a range of bore sizes, which eliminates the need to have bores drilled to an exact size. The split shaft compresses to fit smaller-diameter bores.

Screw hole lathe toolholder bushings (sometimes called J bushings) have holes for set screws to secure the cutting tool shaft and provide positive cutting edge alignment.

Split and screw hole lathe toolholder bushings (sometimes called DD bushings) have a split and screw holders to secure reamers, boring bars, and other tools. The split eliminates the need to have bores drilled to an exact size. Screw holes secure the cutting tool shaft and provide positive cutting edge alignment.

Bolt slot lathe toolholder bushings (sometimes called CV bushings) have a set screw slot to provide positive cutting edge alignment and direct tool clamping.

Bolt slot and screw hole lathe toolholder bushings (sometimes called Z bushings) have two set screws and a long slot to provide rigid, positive cutting edge alignment.
