Effortless operation: The robust cutting element minimizes resistance, enabling efficient, precise, and smooth threading in any situation. Comfortable use: An integrated guiding groove with a self-locking function and a precise ruler reduce setup complexity, enabling reliable one-handed handling. Stable and safe handling: A massive forged frame and a non-slip grip reduce the risk of slipping or tool damage, providing consistently stable guidance for precise results in every application. Simplified threading: Enables simultaneous internal and external threading with a single tool, compatible with standard drill machines, significantly reducing tool changes. Use scenarios: - On-site plumbing in tight spaces: quickly thread new pipe ends with one tool. - Maintenance and repair: restore damaged pipe threads without swapping equipment. - Workshop projects: fast inner and outer threading on small-diameter pipes using standard drill machines.
