Accupro 587116 Tapping Adapter 1 in Pipe Size 3 Adapter

Product Description

The ACCUPRO 587116 is a tapping adapter designed to connect a No. 3 adapter tap to a machine spindle for thread-cutting operations. It accepts a tap shank diameter of 1.125 inches and is built for 1 inch pipe tap sizes. The quick-change design allows the tap to be swapped out without removing the holder from the spindle, reducing setup time on repetitive tapping jobs. Machinists, pipefitters, and tool-room technicians use this adapter when tapping pipe threads in production or maintenance environments.

This adapter is suited for use in machining centers, drill presses, and tapping machines where a No. 3 adapter-style tap holder is required. It handles 1 inch pipe tap work in both ferrous and non-ferrous materials. The quick-change feature makes it practical for shops running multiple tap sizes on the same setup. It is a single-piece unit with a package quantity of one.

Installation Notes

Installation is typically performed by a machinist or tool-room technician. Before mounting the adapter, ensure the machine spindle is fully powered down and locked out per OSHA lockout/tagout procedures. Verify that the shank diameter matches the tapping head collet before seating the adapter. Do not force the adapter into a mismatched collet or spindle bore.
