Engraving Tools: The Many Bits
The various engraving tools that can be attached to marking machinery are a vital aspect in the mechanical process of engraving. Without the plethora of sizes available for engraving bits, as they are commonly known, all engraving would end up looking the same. For precision marking, a technique that is utilized for many applications and among many industries, these size details make all the difference. Product identification, which is often done by way of engraving machines in manufacturing industries such as firearms, food and beverage, electronics and jewelry, use engraving tools. Decorative designs, words and phrases are also applied with engraving tools for such varied applications as musical instruments and decorative metal pieces like bowls, plates and other mass produced items. The size of the bit used depends completely on how large the engraving or engravings need to be.
Materials used to create engraving tools like bits must be very strong, since they are often used to pierce the surface of metals and precious stones, all of which are very hard. That is why sub micron carbide, micrograin carbide and diamond are all popular choices for bit materials. They often resemble needles, with the engraving pinpoint on one end and a metallic attachment on the other. The attachment connects the engraving tool to the ram that moves it up and down, back and forth. Most engraving machines are run by CNC machining programs, which also means the design is worked out through programming. This is why precision markings are possible, as well as mass production of the same design over and over again without variance. Sizes of these engraving tools can vary from the length of the bit to the thickness of the bit, from tiny and thin to long and thick and everywhere in between.
