Milwaukee Spindle Lock Button
Model Number: 42-42-1030
The Milwaukee 42-42-1030 is a genuine OEM Spindle Lock Button for use in compatible Milwaukee circular saws. The spindle lock button is the operator-actuated button that engages a pin to arrest the blade arbor's rotation — holding the spindle stationary while the operator tightens or removes the blade bolt using a wrench for blade changes. The spindle lock must engage cleanly and hold the arbor firmly against the torque applied during blade changes without slipping, then release positively when the button is released so the blade can rotate freely during cutting. A broken, stuck, or non-engaging spindle lock button that prevents hands-free blade changes requires replacement to restore safe, convenient blade changing on compatible Milwaukee circular saws.
Using a genuine Milwaukee OEM spindle lock button ensures the correct engagement geometry and actuation profile for the arbor lock mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct button for your specific unit.
