Parlec 7711-043 Tapping Adapter 7/16 Inch Numertap 700

Product Description

The PARLEC 7711-043 is a quick-change tapping adapter designed for use in CNC machining centers and tapping operations where precise, repeatable thread cutting is required. Built to the NUMERTAP 700 series standard, this adapter accepts a 7/16 inch tap with a 0.323-inch tap shank diameter and a 0.242-inch tap square size. The outside shank diameter measures 1.25 inches, and the projection is 0.700 inches. This adapter is installed by machinists and tooling setup technicians working in production or job-shop environments where quick-change tooling systems reduce changeover time and improve throughput.

The PARLEC 7711-043 fits applications where a NUMERTAP 700 series quick-change tapping system is in use. It is suited for rigid or floating tap operations on ferrous and non-ferrous materials in both production and job-shop settings. The adapter does not include coolant-through capability, making it appropriate for applications where external or flood coolant delivery is used at the spindle or fixture level rather than through the toolholder.

Installation Notes

This adapter is installed by qualified machinists or tooling technicians. Before installing or removing any tapping adapter, ensure the machine spindle is fully stopped and the control is in a safe state. Verify that the tap shank diameter and square size match the adapter specifications before seating the tap. Follow the toolholder manufacturer guidelines and applicable shop safety procedures when torquing any retention hardware.
