Accupro 587054 Tapping Adapter No 8 Tap No 1 Adapter

Product Description

The ACCUPRO 587054 is a quick-change tapping adapter designed to hold No 8 taps in a No 1 adapter body. It accepts taps with a 0.168-inch shank diameter and connects to compatible quick-change tap holders, allowing machinists and toolroom technicians to swap taps rapidly without re-chucking. The quick-change design reduces setup time on CNC machining centers, drill presses, and tapping machines. This adapter provides a secure mechanical connection between the tap shank and the holder, maintaining alignment and reducing the risk of tap breakage during threading operations.

The 587054 is suited for machine shops, production floors, and maintenance facilities where No 8 tapping operations are performed on a regular basis. It fits into standard quick-change tapping systems that accept a No 1 adapter size. Typical applications include through-hole and blind-hole threading in ferrous and non-ferrous materials on vertical machining centers and dedicated tapping machines.
