This set is used for threading pipes, commonly in plumbing, construction, and equipment installation.
It typically includes a ratchet handle and multiple die heads of various sizes (e.g., 1/2", 3/4", 1", 1-1/4" BSPT) for different pipe diameters.
The die heads are made of durable materials like alloy steel and have swarf removal holes for efficient threading.
The ratchet mechanism allows for forward and reverse operation during the threading process.
