Milwaukee Piston
Model Number: 44-62-0058
The Milwaukee 44-62-0058 is a genuine OEM Piston for use in compatible Milwaukee rotary hammers. The piston is the reciprocating component in the rotary hammer's pneumatic impact mechanism — driven back and forth by the wobble shaft or crankshaft, the piston compresses and expands the air column in the barrel to accelerate the striker and deliver hammer blows to the SDS bit. The piston must maintain an effective air seal against the barrel bore throughout its stroke to maximize the pneumatic energy transferred to the striker. A worn, scored, or damaged piston that cannot maintain the required air seal causes reduced impact energy and loss of hammer performance — requiring replacement to restore full pneumatic impact output.
Using a genuine Milwaukee OEM piston ensures the correct diameter, length, and seal geometry for the rotary hammer barrel it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct piston for your specific unit.
