Centaur 000250 Tapping Adapter 1/4 Inch Series CWE0

Product Description

The CENTAUR 000250 is a quick-change tapping adapter designed to securely hold a 1/4 inch tap in compatible tap holders and machine tool spindles. It accepts a Number 0 tap adapter size with a tap shank diameter of 0.255 inches, making it suitable for light-duty tapping operations on drill presses, CNC machines, and tapping arms. The outside shank diameter measures 0.510 inches and the flange diameter is 0.870 inches. Tap depth reaches 0.870 inches. This adapter belongs to the CWE0 series and does not include coolant-through capability. It is sold individually and is the standard choice for machinists and tool-and-die professionals working with small-diameter taps.

The 000250 tapping adapter is used in machine shop environments where repeatable, quick-change tap loading is required. It is well suited for production tapping operations involving small fastener threads, particularly where a Number 0 tap must be driven consistently at controlled depth. Typical applications include light-gauge metal fabrication, precision component manufacturing, and fixture assembly where small-diameter internal threads are machined.

Installation Notes

Installation should be performed by a qualified machinist familiar with tapping adapter systems. Ensure the machine spindle is fully powered down and locked out before inserting or removing the adapter. Verify that the tap shank diameter and adapter size match the holder specification before seating the adapter. Do not force the adapter into a mismatched holder, as this can damage the shank seating surface.
