SDB 206 Mandrel Selection
The SDB206 uses two different size heads to cover its machining range. For machining
workpieces 2.28" through 4-3/8" I.D., the optional small head is used. The large head is used on
pipes over 3-7/8" I.D. These mandrels have three legs which expand equally to contact the inside
walls of the workpiece when the draw bolt is tightened.
Measure the pipe I.D. that is to be prepared. Turn to page six (6) to select the proper mandrel leg
extension. The leg extensions are stamped with a reference number to indicate size of pipe that
they will fit. Once you have determined the mandrel arrangement that is required, attach leg
extensions to the blade with the captive screws.

A light oil coating on the mandrel will give a longer life and smoother operation.
