Product Description

The PARLEC 30-118 is a quick-change tapping adapter designed for use with 1-1/4 inch taps in CNC machining and production tapping applications. Part of the NUMERTAP 300 Series, it accepts a tap with a 1.021 inch shank diameter and a 0.766 inch square drive size. The adapter features a 1.770 inch projection and a 2.830 inch flange diameter, with an outside shank diameter of 1.890 inches. It is installed by machinists and tooling technicians to provide accurate, repeatable tap alignment and reduce tap breakage in high-volume threading operations.
