Accupro 587265 Tapping Adapter 5/16 Inch Quick-change

Product Description

The ACCUPRO 587265 is a tapping adapter designed to secure and drive taps in machining and metalworking applications. It accepts a 5/16 inch tap with a shank diameter of 0.318 inches and is classified as Adapter Size Number 1. The quick-change design allows the tap to be loaded and released without removing the holder from the spindle, reducing setup time on the machine. This adapter is installed by machinists, tool and die makers, and production shop technicians working with CNC machines, drill presses, or tapping heads.

This adapter is suited for shops running production tapping operations where fast changeover between tap sizes is a priority. It is appropriate for both manual and CNC tapping setups where a standard quick-change tapping system is in use. The Number 1 adapter size corresponds to a defined shank diameter range, making it compatible with coordinating quick-change tap holders within the same system. Each package contains one adapter.
