Sleeveless Sander Arbor 1/4"
PN 3012-0025A

This arbor is used when you need to reduce a female arbor from 1/2" down to a 1/4 shaft. An example would be a sanding drum with a female connection that you would like to use on a low speed flexible shaft or small drill chuck.

The large end is 1/2” diameter to fit into the drum. The small end is 1/4” diameter.
