Milwaukee Backing Flange
Model Number: 43-34-3000
The Milwaukee 43-34-3000 is a genuine OEM Backing Flange for use in compatible Milwaukee grinders. The backing flange — also called the inner flange — is the fixed disc that mounts directly to the grinder's spindle and provides the inner clamping face against which the grinding wheel seats. Working with the outer flange nut, the backing flange sandwiches the grinding wheel between two clamping faces to generate the friction grip that secures the wheel to the spindle during operation. The backing flange must be perfectly flat on its clamping face to apply uniform pressure across the wheel hub and prevent cracking the wheel from uneven clamping stress. A damaged, bent, or cracked backing flange requires replacement to ensure safe, secure wheel mounting.
Using a genuine Milwaukee OEM backing flange ensures the correct spindle bore, flange diameter, and clamping face geometry for the grinder it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct flange for your specific unit.
