About the Straight Shaft Arbor

We designed this chuck arbor to mount our 1/4″ and 3/8″ drill chucks in our multi-tool holders with 3/8″ mounting holes*. This straight shaft arbor will also work with our 3/8″ insert holder tool post (P/N 7600). It will work with any chuck that has a 3/8 x 24 thread. It has a 3/8″ diameter straight shaft with a machined flat for holding in the posts. Ensure the flat surface on the arbor is oriented toward the top of the tool post, so the 10-32 x 3/4″ SHC screw will be perpendicular to the flat. This orientation will assure that the arbor does not turn or move when force is exerted on the tool.

Just remove the existing arbor from the chuck and replace it with P/N 11850 arbor.
