One of most terrible tasks in aircraft maintenance is sealant removal. Although terrible, still need someone to finish. Sealant is one of the important elements for aircraft family. That's why I developed a tiny but powerful tooling for aircraft. It's only 13 ozs in weight and 8 inches in length and uses vibration force side by side with 37,800 strokes per minutes. The cutting tip is safe with all metal and non-metal substrates. Further, the cutting tip is very easy to resharpen.
