Does DW7440 stand fit the DWE7480 or DW745 table saws?
No it will not.The DW7440 will fit the DW744 and DW744X table saws only.
Can the DW7440RS be used to mount any other portable tool such as the DW735 planer?
The stand is not recommended for use with any miter saw.
The stand was approved by UL for use with the DW744 and DW745.
The stand will work with most, but not all, other portable table saws. We do not have a listing of what brands or models of other table saws that this stand will accommodate. When using this stand, the most important thing to determine when using another brand saw is that ALL four fastening holes on the base of the table saw must be fastened to the brackets on the DW7440RS to allow them to connect to the stand rail so the brackets are parallel to each other.
