Milwaukee Woodruff Key
Model Number: 06-42-1200
The Milwaukee 06-42-1200 is a genuine OEM Woodruff Key for use in compatible Milwaukee tools. A Woodruff key is a semi-circular, flat-sided precision key that fits into a corresponding semi-circular keyway machined into a shaft — with the mating component such as a gear, pulley, fan, or sprocket featuring a rectangular keyway slot that the key also engages. When assembled, the Woodruff key locks the component to the shaft in rotational alignment, ensuring that the shaft and the component rotate together as a single unit and that motor torque is transferred directly without slippage. A missing, sheared, or worn Woodruff key allows the component to rotate independently of the shaft — resulting in loss of drive, irregular performance, or complete drivetrain failure — requiring replacement to restore secure shaft-to-component coupling and reliable drivetrain operation.
Using a genuine Milwaukee OEM Woodruff key ensures the correct dimensional specification, material hardness, and keyway fit for the shaft and component it serves. Non-OEM keys may not match the original dimensional tolerances, leading to excessive play in the keyway or improper load transfer under torque. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct Woodruff key for your specific unit.
