A honing mandrel having an elongated body with a passageway extending along the length thereof including at least one open sided portion, the mandrel including an abrasive assembly positioned for radial movement in the open sided passageway portion having a radial outer surface formed of an abrasive material and a radial inner portion including spaced surfaces acutely angularly oriented relative to the axis of the mandrel body, cooperatively engageable surfaces on the abrasive assembly and on the body to prevent relative axial movement but not relative radial movement therebetween, and an operator member positioned in the passageway for axial movement therein, the operator member having surface portions thereon acutely angularly oriented relative to the axis of the mandrel body and positioned to make surface-to-surface slidable engagement with respective ones of the inner surfaces on the abrasive assembly whereby axial movements of the operator member in one direction relative to the abrasive assembly will produce radial movement of the abrasive assembly in an outward radial direction, the abrasive assembly and the operator member having adjacent side surfaces with other engaged portions including cooperatively engageable surfaces formed thereon which produce radial movement of the abrasive assembly in an inward direction when the operator member is moved in an axial direction opposite from the axial direction that produced the radial outward movement of the abrasive assembly.
