The Etching/Engraving Tool: Explore and Explore Air by Chomas Creations You can engrave on pretty much anything you can fit under the rollers of the Cricut Explore, Explore Air, and Explore Air 2. Will NOT work in the Explore One or Cricut Maker. Simply add the engraving tip where you would normally put your pens and engrave anything you would typically cut. Please make sure you use maximum pressure settings. Hard metals, such as stainless steel do not work well, since it is a very hard metal. Aluminum blanks will work better.
