Parlec 7711-062 Tapping Adapter Numertap 700 Series

Product Description

The PARLEC 7711-062 is a quick-change tapping adapter designed for rigid tapping applications in CNC machining centers and tapping machines. It features a 0.48-inch tap shank diameter and a 0.36-inch tap square size, providing a secure, positive drive connection to the tap. The outside shank diameter measures 1.25 inches, and the adapter projects 0.70 inches from the holder face. This adapter is part of the NUMERTAP 700 series and is installed by machinists and tooling specialists in production and job-shop environments.

The 7711-062 is suited for use in rigid tapping operations where consistent thread quality and repeatable depth are required. The quick-change interface allows faster tap exchanges without removing the holder from the spindle, reducing setup time on tapping cells and multi-operation machining centers. No coolant-through capability is present on this adapter, making it appropriate for applications where external or flood coolant is used at the cutting zone.

Installation is performed by machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe state before changing or seating the adapter. Verify that the tap shank diameter and square size match the tap being used before securing the adapter. Follow the machine tool manufacturer guidelines for torque and runout specifications when seating any quick-change tapping component.
