Milwaukee Back Flange
Model Number: 43-34-0825
The Milwaukee 43-34-0825 is a genuine OEM Back Flange for use in compatible Milwaukee grinders and cutting tools. The back flange — also called the inner flange or backing flange — is the fixed disc-shaped component that mounts to the arbor shaft and provides the rear clamping surface against which the abrasive wheel or cutting disc seats. Together with the outer clamping nut, the back flange clamps the wheel securely on the spindle, ensuring it is correctly centered and held flat against both clamping faces. A warped, damaged, or incorrectly sized back flange that does not provide even, full-face clamping contact with the wheel can cause wheel vibration, lateral run-out, or catastrophic wheel failure during operation — a serious safety hazard requiring immediate remedy.
Using a genuine Milwaukee OEM back flange ensures the correct diameter, bore size, and face flatness for the spindle and wheel it supports. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct back flange for your specific unit.
