Triton TROS125 Random Orbit Sander Review

Random orbit sanders are one of the most commoditised tools in a workshop. They all spin a 5 in pad in an orbit, they all take hook-and-loop discs, and the difference between a cheap one and an expensive one is not what most people think.

What actually differs

Stroke size. Not usually listed at this price, and it determines aggression. A larger stroke removes material faster and leaves a coarser pattern.

Pad brake. A sander whose pad spins up when lifted will gouge a curved scar when set back down on the work. Premium machines brake the pad; cheap ones vary.

Build life. This is where the money goes. Bearings, the pad mount and the switch are what fail, and a sander used daily will find those limits in a year or two where a weekend user never will.

Dust extraction design. Every sander has a port. How well the holes in the pad line up and how much of the dust actually leaves at the pad varies enormously.

The bag is not dust collection

This applies to every sander in this class regardless of brand. The bag catches the coarse fraction and lets the fine dust — the part that stays in the air and in your lungs — straight through the fabric.

Connect it to a vacuum. Any vacuum is a large improvement, and one with a HEPA filter is the right answer. Abrasive also lasts noticeably longer when the dust is pulled away rather than being ground back into the surface.

Technique beats specification

Let the sander’s weight do the work. Pressing down slows the orbit, generates heat, and produces the swirl marks people blame on the machine.

Move it slowly — much more slowly than feels natural — and do not skip grits. Going from 80 to 180 leaves 80-grit scratches that the 180 cannot remove but the finish will happily highlight.
