Accupro 587263 Tapping Adapter No 12 Tap Quick-change

Product Description

The ACCUPRO 587263 is a quick-change tapping adapter designed for use with Number 12 taps and a Number 1 adapter size. It accepts a tap shank diameter of 0.22 inches, allowing it to securely hold standard Number 12 taps during threading operations on a drill press, CNC machining center, or tapping machine. The quick-change mechanism lets machinists swap taps without removing the entire holder from the spindle, reducing changeover time during production runs. This adapter is suited for light to medium threading work on metals and engineered plastics. It is commonly installed by machinists and toolroom technicians working in manufacturing and maintenance environments.

This tapping adapter is used in machine shop and industrial maintenance settings where threaded holes of Number 12 size are required. It fits standard quick-change tapping systems and is appropriate for both manual and CNC-controlled tapping operations. Typical applications include production machining of metal components, fixture fabrication, and maintenance repair operations where consistent thread quality and fast tap changes are priorities.

Compatibility

Designed as an OEM-style replacement or standard fitment adapter for quick-change tapping systems that accept a Number 1 adapter size and Number 12 tap shanks with a 0.22-inch shank diameter.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with quick-change tapping systems. Before installing or changing the adapter, ensure the machine spindle is fully stopped and all energy sources are locked out per OSHA lockout/tagout procedures. Verify that the tap shank diameter matches the adapter bore before seating the tap to prevent runout or damage to the workpiece thread. Do not force the tap into the adapter if resistance is felt; inspect both components for debris or wear before assembly.
