Jonard PB-3R Burnishing Tool with 6 Rods and 6 Blades

The Jonard Tools® PB-3R Pocket Burnisher, with flat and round blades, is used to remove the oxide layer from the precious metals of relay contacts. Adjust length and rigidity of the abrasive burnishing blade by varying the exposed length in the chuck. Due to plastic housing, the burnishing pen can be used on live contacts without any shocks or shorts. It removes the oxide layer or corrosion off contacts without leaving filings or debris.

The PB-3R burnisher has a removable cap. It comes with 6 flat 0.0035" blades and 6 rods (0.020" in diameter), stored in the opposite end of the pen. The tool is 4.5" long and .375" in diameter.
