Milwaukee Pinion for Select 4-1/2 in. Angle Grinders
Model Number: 14-46-0417
The Milwaukee 14-46-0417 is a genuine OEM metal Pinion for select Milwaukee 4-1/2 in. compact angle grinders including the 6121-30, 6146-30, 6146-31, and 6146-33. The pinion is the small drive gear in the angle grinder's gearcase that meshes with the larger bevel gear to transfer motor rotation to the spindle — converting the motor's inline rotation to the right-angle drive that turns the grinding or cutting wheel. The pinion must remain correctly meshed with the bevel gear and properly supported by its bearing to deliver smooth, efficient power transmission to the wheel at the high RPM these grinders operate. A worn, chipped, or damaged pinion that causes grinding noise, vibration, or loss of power transfer requires replacement to restore correct gearcase operation on the compatible angle grinder.
Using a genuine Milwaukee OEM pinion ensures the correct gear tooth profile and fit for your specific angle grinder. Always verify your catalog number and serial number before ordering to confirm this is the correct pinion for your specific unit.
