Parlec 7711-8 Tapping Adapter Numertap 700

Product Description

The PARLEC 7711-#8 is a quick-change tapping adapter designed for use with NUMERTAP 700 series tooling systems. It accepts a tap shank diameter of 0.168 inches and a tap square size of 0.131 inches, making it suited for smaller tap sizes in precision threading applications. The adapter features a projection of 0.700 inches and an outside shank diameter of 1.250 inches. It is installed by machinists and toolroom technicians working on CNC machining centers, drill presses, and tapping machines where repeatable, rigid tap holding is required.

This adapter is intended for use in production and job-shop environments where the NUMERTAP 700 quick-change system is in place. It is well suited for threading operations in ferrous and non-ferrous materials where consistent tap alignment and fast changeover are priorities. Note that this adapter does not include coolant-through capability, so external coolant or cutting fluid application should be planned for accordingly.

Compatibility

Designed for use with PARLEC NUMERTAP 700 series quick-change tapping systems. Verify tap shank diameter and square size match the tap being used before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with quick-change tooling systems. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing or seating any adapter. Confirm the tap shank and square dimensions match this adapter before assembly to avoid damage to the tap or holder. This adapter does not support coolant-through delivery, so plan for alternative cutting fluid application at the point of cut.
