Accupro 587264 Tapping Adapter 1/4 Inch Quick-change

Product Description

The ACCUPRO 587264 is a tapping adapter designed to connect taps to quick-change toolholding systems in machine shop and production tapping applications. This adapter accepts a 1/4 inch tap with a shank diameter of 0.255 inches and is classified as a Size 1 tap adapter. It is intended for use with compatible quick-change tapping heads and holders, allowing faster tap changeovers without removing the entire toolholder assembly. Machinists, tool and die makers, and production technicians working with CNC or manual tapping setups will find this adapter a direct-fit component for standard tapping operations.

This tapping adapter is suited for use in production machining environments where quick tap changes are required to maintain cycle times. It fits tapping operations on vertical machining centers, drill presses, and dedicated tapping machines. The adapter is sold individually and is appropriate for shops running 1/4 inch taps on Size 1 quick-change tapping systems. Typical applications include threading operations in steel, aluminum, and similar machinable materials in both job shop and high-volume production settings.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with quick-change tapping systems.
