PVC Pipe Threader Tool Sch 80+ PVC & CPVC CTS Fit: Designed for Sch 80 PVC pipe or PVC pipe with Sch 80-level wall thickness or thicker in 1/2", 3/4", and 1" sizes. Minimum wall thickness reference: 1/2" ≥ 0.147", 3/4" ≥ 0.154", 1" ≥ 0.179". For CPVC CTS, use only on fittings with enough wall thickness to threading. Not for metal pipe, Sch 40 PVC, SDR, or thin-wall pipe. Internal & External Threading: The integrated cutter design helps cut, refresh, or clean up usable internal and external threads on repair points, helping improve fit when repairing pipe ends or fitting connections. Spring-Hex Shanks for Tool-Head Stability: Includes three 50 mm drill-hex shanks with spring-ends. The spring-loaded helps secure the threader head to the shank, reducing looseness and improving control during use. Solid Metal Cutter Construction: Built with solid metal cutters for Sch 80+ PVC pipe and CPVC CTS fitting connection repair. Clean cutting edges help steady cutting performance when used with proper setup, alignment, and low-speed operation. Controlled Low-Speed Operation: Attach to a drill, secure the pipe or fitting in a bench vise, keep the cutter aligned with the pipe end or fitting opening, and thread slowly at low speed for better control and cleaner repair results.
