Designed to work in sequence, these files strategically remove dentin along only a portion of the file. The larger tapers work toward the orifice, allowing the smaller tapers to more easily work toward the apex. These files are passively carried down the canal in succession, resulting in a canal that is smoothly tapered from apex to orifice, creating a shape that can be easily obturated.
