Bush Chuck
B-12 (3731002) Bush Chuck is used in replacement of the standard B-12 Quick Release Chuck and is used with various Quick Release Tap Bushes with clutch to allow you to use the full range of certain tappers.
This situation arises where the size of the tap is too large for the standard tap holders. In this case you choose the appropriate Bush Chuck and Quick Release tap bush so you can fully utilise the range of your tool, namely the 8306032 (SUPERGOMAS16) 16MM pistol grip pneumatic tapper.
