Parlec 7716-106 Tapping Adapter Numertap 770

Product Description

The PARLEC 7716-106 is a quick-change tapping adapter designed for use with NUMERTAP 770 series tooling systems. It accepts a tap shank diameter of 0.896 inches and a tap square size of 0.672 inches, making it compatible with mid-range tap sizes commonly used in CNC machining and production tapping operations. The outside shank diameter measures 1.25 inches, and the projection is 2.25 inches. This adapter is intended for installation by machinists and tooling technicians working with rigid or floating tapping setups on machining centers and drill presses.

This tapping adapter fits production and job-shop environments where quick-change tooling is used to reduce setup time between tap changes. It is suited for applications in ferrous and non-ferrous materials where consistent tap alignment and positive drive are required. The NUMERTAP 770 series is a common platform in CNC tapping operations on vertical and horizontal machining centers. Note that this adapter does not include coolant-through capability, so it is best applied in operations where flood or mist coolant is supplied externally.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before inserting or removing the adapter. Verify that the tap shank and square dimensions match the adapter specifications before seating the tap. Confirm proper engagement with the NUMERTAP 770 holder before beginning any tapping cycle.
