Accupro 587267 Tapping Adapter 7/16 Inch Quick-change

Product Description

The ACCUPRO 587267 is a Number 1 tapping adapter designed to hold 7/16 inch taps in quick-change tap holders and drive systems. The adapter features a 0.323 inch tap shank diameter and is built for use with compatible quick-change tooling systems common in production and maintenance machining environments. It allows machinists and tool and die technicians to swap taps rapidly without removing the entire holder from the spindle, reducing cycle time on tapping operations. Suitable for use on drill presses, CNC machining centers, and dedicated tapping machines where quick-change tooling is already in use.

This adapter is intended for shops and tradespeople running repetitive tapping operations across mild steel, aluminum, and similar materials where frequent tap changes are expected. The Number 1 adapter size corresponds to a specific tap shank diameter class, so verifying the shank diameter of the tap before installation is essential. It ships as a single unit and is stocked for individual purchase with no minimum order requirement beyond one piece.

Installation Notes

Installation is performed by qualified machinists or tool and die technicians familiar with quick-change tooling systems. Ensure the machine spindle is fully stopped and locked out before inserting or removing the adapter. Confirm the tap shank diameter matches the adapter bore before seating the tap to avoid damage to the adapter or workpiece. Follow the tooling manufacturer guidelines for torque and engagement depth specific to your quick-change holder model.
