Parlec 7711-037 Tapping Adapter Numertap 700

Product Description

The PARLEC 7711-037 is a quick-change tapping adapter designed for use with NUMERTAP 700 Series tooling systems. It accepts a tap shank diameter of 0.381 inches and a tap square size of 0.286 inches, providing a secure, repeatable connection between the tap and the machine spindle. With a projection of 0.700 inches and an outside shank diameter of 1.250 inches, this adapter is built for precision tapping operations on CNC machining centers and tapping machines. It does not support coolant-through configurations. Machinists and toolroom technicians rely on this adapter for consistent tap alignment and fast tool changes in production environments.

This adapter is suited for production tapping applications in both job shop and high-volume manufacturing settings. The quick-change interface of the NUMERTAP 700 Series reduces tool change time and supports repeatable tap positioning without re-indicating. Typical installations involve vertical or horizontal CNC machining centers running rigid or floating tapping cycles. The adapter is compatible with taps sized to the 0.381-inch shank and 0.286-inch square drive specifications.
