When I tried this accessory for my milling machine, I was blown away by the precision of the engraving. It made intricate designs and lettering a breeze, and the tungsten carbide material ensured durability. The only downside was that it took a bit of practice to get the settings right, but once I did, it worked flawlessly. Overall, a great investment for any milling enthusiast looking to add some personalization to their projects.
