Milwaukee Baffle for M18 FUEL 4-1/2 in./5 in. Grinder 2780-20
Model Number: 42-14-0040
The Milwaukee 42-14-0040 is a genuine OEM Baffle for the Milwaukee M18 FUEL 4-1/2 in. / 5 in. Grinder 2780-20. The baffle is the internal airflow deflector that directs cooling air through the 2780-20's motor housing — channeling the airflow generated by the motor's cooling fan across the POWERSTATE brushless motor's windings and rotor to maintain safe operating temperatures during demanding grinding, surface preparation, and cutting applications. The 2780-20 is engineered to deliver maximum sustained power at 8,500 RPM, and correct airflow management through the baffle is critical to sustaining that output without the thermal protection system reducing performance. A cracked, broken, or dislodged baffle that disrupts internal airflow and causes the motor to overheat requires replacement to restore correct thermal management on the 2780-20.
Using a genuine Milwaukee OEM baffle ensures the correct airflow geometry for the M18 FUEL 4-1/2 in. / 5 in. Grinder 2780-20. Always verify your catalog number before ordering to confirm this is the correct baffle for your specific unit.
