Milwaukee Spindle
Model Number: 32-75-0018
The Milwaukee 32-75-0018 is a genuine OEM Spindle, officially described by Milwaukee as the Spindle with Pin, for the M18 FUEL 1-1/2 in. magnetic drill. The spindle is the rotating output shaft at the heart of the drill's drive train: it carries the cutting tool, whether an annular cutter mounted directly or a twist drill held in a chuck on the 1/2 in. drill chuck adapter, and it transmits the torque and speed from the two-speed gearbox to the work. It is a precision-ground shaft whose concentricity, bearing and bushing fit, and pin location are held to tight tolerances, so a worn, bent, or damaged spindle shows up as runout, wobble, poor hole quality, vibration, or difficulty seating cutters. Because it is machined to match the gearcase bores and the drive components, using the genuine Milwaukee OEM spindle restores true, concentric rotation, where an off-spec shaft can run out, chew bushings, or fail to hold a cutter securely. As the official name indicates, this part is supplied with its pin.
This spindle is identified as the Spindle with Pin, Figure 23, on the Milwaukee service parts lists for these drills: the 2787-20 standard magnetic drill, bulletin 54-46-0410, and the 2788-20 lineman magnetic drill, bulletin 54-46-0420, along with the kit and variant versions 2787-22 (serial G56A), 2787-059 (serial G96A), and 2788-20 (serial G57A). Replacing the spindle is an internal gearcase repair: Milwaukee specifies the Spindle Bushing Press Fixture, number 61-30-2788, for servicing the spindle and its bushing, so this is a shop-level job rather than a drop-in swap, and the surrounding drive components, including Shift Bracket B (42-36-0018), the steel ball (02-02-0103), and the shift springs (40-50-0023 and 40-50-0038), should be inspected and ordered separately as needed. The annular cutter, drill chuck, and 1/2 in. drill chuck adapter that mount to the spindle are separate items. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
