General characteristics

Reaming is a machining process that increases the diameter of a previously drilled cylindrical hole to improve dimensional and geometrical accuracy and/or reduce surface roughness. The reaming process is carried out using multi-blade tools called reamers. During reaming, the primary (rotary) motion is performed by the tool. The feed motion is performed in a direction parallel to the axis of the reamer by the tool or workpiece.
