The beauty of the Parf system lies in its accuracy, in particular the close fit of Parf dogs and accessories in the 20mm dog holes. Depending on the material chosen for the bench top, sometimes a stray wood whisker or change in humidity can affect the fit.

The UJK Reamer is designed to remedy the problem and restore the quality of 20mm holes. The Reamer removes stray wood fibres that hinder the insertion of UJK bench dogs and Parf Guide System accessories. The Reamer improves the quality of holes in bench tops. The Parf System Reamer is made from stainless steel for use in a power drill.
