What is the difference between burnishing and rotary engraving?
Burnishing is a surface engraving technique that bridges the gap between diamond drag and deep-cut rotary engraving. It is an excellent way to produce broad stroke engraving on metals that may be difficult or impossible to engrave with a standard engraving cutter.
The burnisher is a carbide or diamond-tipped, faceted tool that is generally used on coated metals such as lacquered brass. It is a rotating tool that is designed to remove the coating and expose the bare metal. Unlike the diamond graver which produces a narrow line width, the burnisher is available in the same widths as rotary engraving cutters so it is possible to achieve line widths and visual effects as you would with standard cutters and fonts.
