VAP-BU-0010 - 18 Facets 10x7 mm Medium

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.
