Dual function design: cuts internal and external threads on PVC pipes (1/2" and 3/4"), eliminating the need for multiple tools. Premium material: high-hardness tungsten steel, providing long life, high concentricity, and stable threading without slipping or drifting. Easy to use: ergonomic handles for a firm grip; ratcheting mechanism enables smooth, controlled threading with minimal effort, suitable for professionals and hobbyists. Compact and portable: lightweight yet sturdy construction; easy to carry to job sites or store in a toolbox. Applications: ideal for plumbers, handymen, and home improvement projects. Use scenarios: 1) On-site installation or repair of PVC supply lines in kitchens or bathrooms, threading 1/2" or 3/4" pipes for fittings. 2) Irrigation or sprinkler system work, quickly adding threaded adapters to PVC lines. 3) DIY projects in tight spaces where precise, durable PVC threading is required.
