Parlec 7716-6-100 Tapping Adapter Numertap 770

Product Description

The PARLEC 7716-6-100 is a quick-change tapping adapter designed for use with the NUMERTAP 770 series tooling system. It accepts a tap shank diameter of 0.8 inches with a tap square size of 0.6 inches, making it suited for threading operations on CNC machining centers and tapping machines. The outside shank diameter measures 1.25 inches and the projection is 6.7 inches. Machinists and tooling technicians install this adapter to connect taps to compatible NUMERTAP 770 quick-change holders, reducing tap changeover time and maintaining alignment during threading cycles.

This tapping adapter is used in production machining environments where repeatable tap positioning and fast changeover are required. It is appropriate for both ferrous and non-ferrous threading applications on vertical and horizontal machining centers. The NUMERTAP 770 series is a common platform in shops running high-volume tapping operations where tooling consistency matters. Coolant-through capability is not available on this unit, so external coolant application should be planned accordingly during setup.

Key Features

• Quick-change interface for fast tap swaps without removing the holder from the spindle
• Tap shank diameter of 0.8 inches for secure tap engagement
• Tap square size of 0.6 inches for positive rotational drive
• Outside shank diameter of 1.25 inches for rigid spindle connection
• Projection of 6.7 inches to reach deeper features or clear workholding
• No coolant-through - external coolant delivery required

Compatibility

Designed for use with the PARLEC NUMERTAP 770 series quick-change tapping system.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before mounting or removing the adapter. Ensure the tap shank and square dimensions match the tap being used before assembly. Verify torque and feed rate settings in the machine controller are appropriate for the tap size and material before running the cycle.
