Engraving with Diamond Drill Bits

The engraving industry is a modestly-sized market in America. There are engravers who prefer working on classic firearms and even etch artworks into objects such as swords and knives. The federal government prints currency using engraved metal plates. Others are more challenging, such as engraving glass items. Nowadays, some glass objects are often etched by laser imagery but there are people who take the classic route and use diamond burrs. Since there’s a danger of chipping for the item being engraved, there are some pointers to consider:

Start by researching on diamond burrs with finer grades. The higher the grade number, the finer the grit. Some experts say a bit with 120 grit will work well in general engraving and higher grits help produce darker areas in the engraving. Consider reducing the rotary tool’s speed to allow for more defined edges.

Take note of the handpiece’s maintenance condition when engraving. Check the collet and bearings for signs of wear as they can contribute to chipping as a result of wobbles. Make sure that the bur itself is not locked too tight or the handpiece will be stripped. Apply water, or a sponge soaked in water and soap on the surface area to help lubricate the bit. Precaution is everything when you’re engraving.
