<p>The Chomas Creations precision tip etching / engraving tool fits in the blade housing unit in the electronic cutting machines noted in the bullets above.</p> <p>It can be used to finely engrave and/or etch many materials, including acrylic, plastic, glass (if your machine allows this), metal (copper, bronze, silver, aluminum...), and metal clay (would not advise to use on leather unless a precise small area is being worked on, but may tear it or paper).</p> <p>Although this tool will etch or engrave on stainless steel, the electronic cutting machines themselves do not provide enough pressure to do so. Any material used with this tool should sit on the machine's mat and fit under the machine's rollers.</p> <p>Ensure the machine you use can accommodate the media you desire before committing to specific media use.</p> <p>Note before you order: This tool does NOT FIT in these Cricut models: Explore, Explore Air, Explore Air 2, Explore One or Maker.</p>
