The KMG small wheel attachment  (SWF) bolts directly to the top of the tooling
arm.  The wheels slide into the fork arms and are interchangeable.  The contact
wheels have a 70 durometer rubber surface for smooth operation, excellent
finish, and extended belt life.

NOTE: Small wheels need to run slower due to high revs.
Use caution and slower speeds to prevent damage. Monitor the heat to determine
the best speed for a specific wheel diameter.  Smaller wheels require slower
speeds to prevent over heating. Operate at a speed that keeps the bearings cool
enough to comfortably touch.
