Drill engraving

In drill engraving the tool used is a rotating bur in the handpiece of an electric drill. This tool can be used to create surface effects similar to those of hand engraving techniques but can also cut into the glass more deeply to create the illusion of three dimensions. This technique is often called 'flexible drive engraving', referring to the type of drill familiar from the dental surgery, which has a flexible drive shaft running from a pendant motor, but other types of drill are also used.
