Milwaukee Replacement Impeller
Model Number: 49-16-2771-S
The Milwaukee 49-16-2771-S is a genuine OEM Replacement Impeller for compatible Milwaukee power tools — the rotating fan component that moves air through the tool's motor cooling pathway for thermal management during sustained power tool operation. The impeller is a critical motor cooling component — its rotation at motor speed draws cooling air through the motor housing to remove the heat generated by motor operation and dissipate it out of the tool body before the motor windings and internal components reach temperatures that cause thermal damage. When the impeller is damaged from impact or debris ingestion, cracked from age or thermal cycling, or its blades are worn from sustained abrasive environment operation, the tool's cooling airflow decreases, leading to elevated motor temperatures that reduce tool life and can trigger thermal protection shutdowns during sustained use.
Using a genuine Milwaukee OEM replacement impeller ensures the correct blade geometry, hub bore, and dimensional specification for the specific Milwaukee tool model's motor shaft and housing airflow path — an impeller with incorrect blade geometry or hub dimensions would not provide the designed cooling airflow for the motor's thermal management requirements. Always verify your specific Milwaukee tool model number and serial number at milwaukeetool.com before ordering replacement impeller components.
