P.K. Neuses Burnishing Tool

Heavy duty type with 33% greater contact burnishing area. Blade is 1/4" (6.00 mm) wide, .010" (.255 mm) thick and 3 1/4" (8.25 cm) long. For peak performance, each tool is in a vinyl case for protection from grease and moisture.
 

"Non-Residual" contact burnishers leave no filings, grit, dust or film on contacts to start a new carbonaceous build-up. They are economical and flexible, with enough stiffness to apply the right pressure to the contact face offering minimum wear on costly contacts. Insulated plastic handles eliminate possible shocks or shorts when working on live contacts. These burnishers have been proven successful by leading manufacturers as the only tool to use in cleaning contacts for longer life and fewer service complaints.

Excellent for pinball and other arcade game contact restoration!

Also good for polishing contacts on other machines like the BMW R series of motorcycles and relays in jukeboxes, etc.
