Rotary engraving produces dust and chips that can interfere with the engraving process or scratch the engraved gift or item. Keep your engravings clean with a chip collector.

Using a chip collector ensures a perfect engraving result as the material residues are immediately sucked up.
It also helps you to keep your rotary engraver clean at all times and reduces maintenance needs.
