Abstract:
The present invention pertains to a cutting tool for removing upset from inside a tube and which does not force splatter into the inside surface of the tube. The cutting tool comprises a holder and means for enabling the tube to move along the holder. The enabling means is connected to the holder. The cutting tool is also comprised of means for removing the upset inside the tube. The removing means is connected to the holder such that as the tube moves along the holder, the removing means removes the upset from the inside of the tube. There is also means for preventing splatter from being forced into the inside of the tube by the enabling means as the tube moves along the holder. Preferably, the enabling means includes a roller connected to the holder such that the holder can roll along the tube on the roller, and the preventing means includes means for introducing fluid upstream from the roller such that the fluid prevents splatter from being rolled into the inside of the tube by the roller as the tube moves along the holder. The fluid creates a fluid barrier which forces the splatter around the roller so the splatter is not rolled into the inside surface of the tube.
