Summary
Milwaukee M18 BOS125-0 is a solid, cordless 125mm random orbital sander that combines robust build quality with controlled finishing and on-site practicality.
Findings
From the bench to the van, the BOS125-0 feels well engineered and sturdy in the hand. The balance is good for a tool of this size, and the grip is comfortable enough to use for extended periods without noticeable fatigue. The variable speed control is responsive, allowing careful finishing at lower speeds for delicate work and more aggressive material removal when required. The 125mm disc system is easy to change with the hook-and-loop fitting holding discs securely flat during operation, which helps achieve consistent finishes. Dust collection is effective when paired with a compatible dust shroud or shop vac, keeping the workpiece clearer and reducing airborne dust for a cleaner, safer workspace. The motor stays reasonably cool under normal use, and the battery integration across the M18 line makes swapping packs between tools straightforward for longer jobs. Overall, the finish quality is consistent and smooth with appropriate grits, making this a dependable choice for professional woodworking and finishing tasks on-site and in the workshop.
