Centaur 205125 Tapping Adapter 1/4 in Size 2 CWE2

Product Description

The CENTAUR 205125 is a quick-change tapping adapter designed for use with Size 2 tap holders in machine tapping operations. Built to the CWE2 series specification, it accepts a 1/4 inch tap size and features a tap shank diameter of 0.562 inches, making it a precision-fit component for production and toolroom environments. The adapter allows for fast tap changes without removing the holder from the machine spindle, reducing setup time on drilling and tapping centers. Machinists, toolroom technicians, and CNC setup personnel are the primary installers of this component.

The CENTAUR 205125 is suited for use on drill presses, CNC machining centers, and tapping machines where repeatable, quick-change tooling is required. It fits within the CWE2 series system and is appropriate for light-duty to medium-duty tapping of 1/4 inch threads. The adapter does not support coolant-through delivery, making it best suited for dry tapping or flood coolant applications where internal coolant feed is not required.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing or seating the adapter. Verify that the tap shank diameter and adapter size match the holder specification before applying torque loads. Follow the machine tool manufacturer guidelines for spindle speed and feed rate when tapping 1/4 inch threads.
