Milwaukee Depth Shaft
Model Number: 45-08-0395
The Milwaukee 45-08-0395 Depth Shaft is a genuine OEM replacement part used across multiple Milwaukee M18 cordless circular saw service parts bulletins, including bulletins 54-40-2630 (and the revised 54-40-2630d6), 54-40-2635, and 54-40-2790R. Confirmed compatibility includes the Milwaukee 2630-20 M18 6-1/2 in. Cordless Circular Saw, 2630-22 kit version, 2730-20 M18 7-1/4 in. Circular Saw, 2731-20 M18 7-1/4 in. Circular Saw, 2636-20 M18 Cordless Circular Saw, and additional Milwaukee cordless circular saw platforms across the M18 and M28 generations covered by these bulletins. The depth shaft is the precision-machined shaft that the saw pivots on as the operator adjusts the cutting depth, holding the upper guard gearcase in correct alignment with the shoe assembly throughout the depth adjustment range. The shaft works in conjunction with the matching Flat Washer (Milwaukee 45-88-1515) and Depth Lever (Milwaukee 44-10-0018), both documented on the same bulletins and sold separately.
A worn, bent, scored, or galled depth shaft can cause binding during depth adjustment, inconsistent or inaccurate depth settings, wobble in the upper guard relative to the shoe, and in severe cases damage to adjacent bearings and guard components. Replacing the shaft with this OEM service part restores correct depth-adjustment pivot action and smooth, accurate depth setting. Service of the gearcase area requires Milwaukee Type 'Y' Grease (Milwaukee 49-08-5270) per bulletin 54-40-2630 specifications, which is the standard lubricant for Milwaukee circular saw gearcases. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering. The 45-08-0395 is specific to the M18 cordless circular saw platforms it serves and is NOT interchangeable with other Milwaukee depth shaft part numbers used across different saws (including 45-08-0155 for the M12 FUEL 5-3/8 in. 2530-20, 45-08-0415 and 45-08-0416 for older corded saws, and 45-08-0420 for some 7-1/4 in. saws on bulletin 54-40-6051). Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment.
