Diamond Engraving Tools
There are two different types of Diamond Engraving cutters. The diamond 'Drag' tool is normally used while the spindle is off so it will not rotate while it engraves. A Drag tool will only 'scratch' the material, the tip is similar to a pencil point and it does not cut very deep. The Drag tool has been very popular through out the years to engrave trophies, dog tags, brass and aluminum labels, etc.
The other type of Diamond Engraving tool is the diamond Burnisher. The Burnisher is a 4 faceted tool and is similar to a chisel point. It is a rotating engraver and comes in various tip sizes. The Burnisher gives a much cleaner and more of a polish than the diamond drag tools.
