Milwaukee Bit Conic Spring
Model Number: 40-50-0082
The Milwaukee 40-50-0082 is a genuine OEM Bit Conic Spring for use in compatible Milwaukee tools. The bit conic spring is a conical compression spring — a spring with a tapered profile that compresses to a nearly flat stack height — used in bit retention and chuck mechanisms to apply a consistent ejection or retention force to the bit shank. The conical geometry allows the spring to compress fully within a very shallow space, making it ideal for compact bit holder assemblies where a cylindrical spring would not fit. The spring must maintain its designed load force throughout the tool's service life to ensure consistent bit ejection or retention with each bit change. A fatigued, broken, or permanently set bit conic spring requires replacement to restore reliable bit retention and ejection performance.
Using a genuine Milwaukee OEM bit conic spring ensures the correct spring rate, free height, and coil geometry for the bit holder mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring for your specific unit.
