Drum Sander
  Holds cloth-backed 1½" wide abrasive strips by means of an adjustable T-clamp that projects from and retract into the wheel by adjusting the cam lock with the locking tool provided.  This means that the wheel does not have to be dismounted to change the paper (unlike the "cone-loc drum sander).  Permanently bonded rubber cushion is grooved for cooling.  High-strength aluminum construction.  6" diameter x 1½" wide x 7/8" bore.  Reducer bushings sold separately. These are not stock items and lead time is about 4 weeks.

MX Split Lap Wheels
 

Well known among major manufacturers, but almost unknown by small manufacturers and retailer/manufacturers. Use of these non-clogging, cool grinding wheels completely eliminates the need for hand filing of castings. The result is smoother and more uniform than hand filing, with much less labor and significantly less gold loss.
