Accupro 587112 Tapping Adapter 1-3/8 Inch Size 3

Product Description

The ACCUPRO 587112 is a quick-change tapping adapter designed to connect a Size 3 tap adapter to a tapping head or machine spindle. The adapter accepts taps with a 1-3/8 inch tap size and features a 1.108 inch tap shank diameter. It is used in CNC machining centers, drill presses, and tapping machines where fast tap changes and consistent thread quality are required. Machinists, tool and die makers, and production machine operators install this adapter as part of a quick-change tooling system to reduce setup time and maintain axial alignment during tapping operations.

This adapter fits into Size 3 quick-change tapping systems and is suited for production environments where multiple tap sizes are run on the same machine. It is appropriate for light to medium-duty tapping in ferrous and non-ferrous materials. The quick-change design allows tap replacement without removing the entire holder from the spindle, which is a common requirement in high-volume threading operations on machining centers and turret drill presses.
