Centaur 100375 Tapping Adapter 3/8 Inch CWE1 Series

Product Description

The CENTAUR 100375 is a quick-change tapping adapter designed for use with 3/8 inch taps in machine tool and production tapping applications. Part of the CWE1 series, this adapter accepts a tap with a shank diameter of 0.381 inches and a tap depth of 1.050 inches. The flange diameter measures 1.180 inches and the outside shank diameter is 0.750 inches. It is installed by machinists and tooling professionals working with CNC machines, drill presses, or tapping heads where repeatable, quick-change tooling setups are required.

This adapter is suited for light to medium production tapping in both job shop and manufacturing environments. The quick-change design allows faster tap swaps without removing the holder from the spindle, reducing setup time on repetitive tapping operations. It is sized for tap adapter size number 1, making it appropriate for smaller tap ranges in standard tapping head systems. Coolant-through capability is not included in this configuration.
