Accupro 587284 Tapping Adapter 7/8 Inch Size 2

Product Description

The ACCUPRO 587284 is a quick-change tapping adapter designed to connect a Size 2 tap holder to tapping tools with a 7/8-inch tap size. The adapter features a 0.697-inch tap shank diameter and is built for use in production and job-shop machining environments where fast, repeatable tap changes reduce cycle time. The quick-change mechanism allows operators to swap taps without removing the entire holder from the machine spindle. It is suited for use with CNC machining centers, drill presses, and tapping machines where accurate thread cutting is required. Machinists and toolroom professionals are the primary installers of this adapter.

This tapping adapter is used in threading operations across general metalworking, manufacturing, and maintenance repair applications. It fits setups where a Size 2 tapping adapter is required to hold a 7/8-inch tap shank. The quick-change feature makes it particularly useful in high-volume production environments where multiple tap sizes are cycled through a single spindle position.

Before installing or removing the adapter, the machine spindle must be fully stopped and powered down in accordance with lockout/tagout procedures. Ensure the tap shank and adapter bore are clean and free of chips or debris before seating the tap. Consult the machine tool manufacturer guidelines for proper torque and retention requirements specific to the tapping system in use.
