Accupro 587078 Tapping Adapter 7/16 in Tap Size 2

Product Description

The ACCUPRO 587078 is a quick-change tapping adapter designed to connect a 7/16 inch tap to a No. 2 adapter drive. The adapter accepts a tap with a 0.323 inch shank diameter and integrates into quick-change tapping systems to reduce changeover time during production or maintenance drilling operations. It is used primarily by machinists and tool-and-die professionals working with tapping heads, CNC machines, or drill presses where rapid tap swapping is required. The quick-change design allows the tap to be released and reseated without removing the drive holder from the spindle.

This adapter is suited for machine shops, metalworking operations, and maintenance facilities where 7/16 inch tapping is performed repeatedly. It is compatible with No. 2 adapter systems and fits taps with the specified 0.323 inch shank diameter. The unit ships individually and is appropriate for both production-run tapping and single-piece repair work.

Compatibility

Installation Notes

Installation is performed by qualified machinists or tool technicians. Ensure the tapping machine or drill press is fully powered down and the spindle is at rest before inserting or removing the adapter. Verify that the tap shank diameter matches the adapter bore before seating. Follow the tapping head manufacturer guidelines for locking and releasing the quick-change mechanism to prevent unintended tap ejection during operation.
