Parlec 7717-100 Tapping Adapter 1 Inch Pipe

Product Description

The PARLEC 7717-100 is a quick-change tapping adapter designed for pipe thread tapping operations in CNC and production machining environments. It accepts a 1-inch pipe tap with a 1.125-inch tap shank diameter and a 0.843-inch tap square size, providing a secure, rigid connection between the machine spindle and the tap. The outside shank diameter measures 1.25 inches, and the adapter projects 2.25 inches. This adapter belongs to the NUMERTAP 770 Series, a system engineered for reliable, repeatable tapping performance in high-volume shop settings. Coolant-through capability is not available on this model.

The 7717-100 is suited for use in vertical and horizontal machining centers, CNC lathes, and drill presses where pipe thread tapping is a regular operation. The quick-change interface allows the operator to swap taps without removing the holder from the spindle, reducing cycle time on multi-tap jobs. It is appropriate for production tapping of 1-inch pipe threads in ferrous and non-ferrous workpieces. Machinists and toolroom professionals working with the NUMERTAP 770 Series tooling system will find this adapter a direct fit within that platform.
