Milwaukee Impacting Assembly
Model Number: 14-46-2820
The Milwaukee 14-46-2820 is a genuine OEM Impacting Assembly for use in compatible Milwaukee M18 FUEL 1/2 in. impact wrenches. The impacting assembly is the complete impact mechanism unit — integrating the hammer, cam shaft, anvil interface, and associated components into a single factory-assembled unit that delivers the rotary-percussive impact action of the impact wrench. As the motor drives the cam shaft, the hammer cycles axially — building kinetic energy, then releasing it in rapid impact blows to the anvil to produce torque output far beyond what the motor alone could sustain. Providing the mechanism as a complete assembly ensures all components are factory-matched and correctly assembled for reliable, consistent impact performance. A worn, damaged, or failed impacting assembly that produces reduced torque, erratic impact cycling, or no impact action requires replacement to restore full impact wrench performance.
Using a genuine Milwaukee OEM impacting assembly ensures the correct cam geometry, hammer mass, and dimensional fit for the M18 FUEL impact wrench it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct assembly for your specific unit.
