The fastest tool for removing porosity on gold, platinum and silver. Our Rotary Burnishers are patented creations made of highly polished tungsten carbide and mounted on 3/32" (2.35mm) shanks. Each burnisher has a 12-, 18- or 36-facet sidewall that produces its own unique effect on metals:
The 12-Facet Burnisher leaves a coarse finish and covers large pinholes on gold & silver.
The 18-Facet Burnisher leaves a medium finish and covers moderate pinholes on all metals.
The 36-Facet Burnisher leaves a fine finish and covers small pinholes on all metals.
