Parlec 7716-3-062 Tapping Adapter Numertap 770

Product Description

The PARLEC 7716-3-062 is a tapping adapter designed for use with rigid and floating tap holders in CNC machining and production tapping operations. It features a tap shank diameter of 0.48 inches and a tap square size of 0.36 inches, making it compatible with appropriately sized taps for threading operations. The outside shank diameter measures 1.25 inches, and the adapter provides a projection of 3.7 inches. Quick-change functionality allows for fast tap exchanges without removing the holder from the spindle, reducing cycle time on production floors. Coolant-through is not supported on this adapter.

This adapter is suited for use in machining centers, CNC lathes with live tooling, and dedicated tapping machines where repeatable tap positioning and quick changeover are required. It is part of the NUMERTAP 770 Series, a system engineered for high-volume production tapping environments. Machinists and CNC tooling specialists working in metal fabrication, automotive, and general manufacturing will find this adapter appropriate for standard threading applications where a 0.48-inch shank tap is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician familiar with tapping adapter systems. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before changing or seating the adapter. Confirm that the tap shank and square dimensions match this adapter before assembly to avoid drive slippage or tap damage during operation. Follow the machine tool manufacturer's guidelines for tool clamping torque and runout verification after installation.
