Makita BO5041K Random Orbit Sander: What to Know
The BO5041K is a corded, 5-inch random orbit sander with a 3.0-amp motor and variable speed from 4,000 to 12,000 OPM, controlled by a dial rather than a trigger-mounted wheel. Makita rates its orbit diameter at 1/8 in., though that nominal fraction converts to roughly 3.2mm while some of Makita's own retailer-facing spec sheets list it as 2.8mm, a minor but real inconsistency between Makita's own published materials that's worth knowing about if you're comparing orbit numbers across brands on paper rather than by feel.
Dust collection uses an included dust bag with a separate nozzle adapter, and the pad uses Makita's own hook-and-loop hole pattern, it is not guaranteed to be identical to DeWalt's or Bosch's pad pattern, so aftermarket discs should be bought as Makita-compatible specifically. This model also includes Makita's adjustable front handle, letting you choke up for corner work or extend it for two-handed control on flat panels.
Independent testing is largely favorable but not uniform: several reviewers report a genuinely smooth, scratch-free result on 220-grit paper, matching Makita's marketing, but also note noticeably more vibration at low speed settings than at high speed, which is the opposite of what most sanders exhibit and is one reason the tool ships with that adjustable front handle for two-handed low-speed control.
