Parlec 7714-050 Tapping Adapter 1/2 Inch Pipe

Product Description

The PARLEC 7714-050 is a quick-change tapping adapter designed for 1/2 inch pipe tap sizes, used in precision tapping operations on CNC machining centers and rigid tapping setups. The adapter features a 0.687 inch tap shank diameter and a 0.515 inch tap square size, providing a secure, repeatable connection between the toolholder and the tap. Part of the NUMERTAP 700 series, this adapter is built for high-accuracy tapping in production machining environments. Machinists and tooling technicians install it as part of a modular quick-change tooling system to reduce setup time and maintain consistent tap alignment across multiple operations.

This adapter is suited for use in production shops running repetitive pipe thread tapping cycles on ferrous and non-ferrous materials. The NUMERTAP 700 series is a modular quick-change system, making this adapter a direct fit for compatible NUMERTAP 700 series toolholders. It is applicable in both horizontal and vertical machining center configurations where rigid or floating tap cycles are programmed. The 0.700 inch projection and 1.250 inch outside shank diameter are appropriate for standard toolholder pockets in this series.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is removed from the machine before inserting or removing the tapping adapter. Confirm that the tap shank and square dimensions match the adapter specifications before assembly. Consult the NUMERTAP 700 series assembly documentation to verify proper engagement depth and retention in the toolholder body.
