Purpose: Designed for plumbing projects and home repairs to create secure, leak-resistant connections in PVC pipes.
Sizes: Includes three interchangeable dies for common pipe sizes: 1/2-inch, 3/4-inch, and 1-inch.
Material: The main body and handle appear to be made of plastic, while the cutting dies are likely alloy or metal.
Functionality: The dies are inserted into the central yellow handle assembly, which is then rotated around the pipe end to cut the tapered threads.
