Our take on the Mirka DEOS 343XCV 3 x 4 in. Electric Orbital Sander

The Mirka DEOS 343XCV is a compact electric orbital sander with a 3 x 4 in. pad, built for detail and edge work that a full-size 6 in. sander cannot reach. Its brushless motor runs 5,000 to 10,000 orbits per minute with variable speed, and the 3 mm orbit keeps it controllable on door frames, window trim and solid surface. It is central-vacuum ready, so dust extraction depends on the vacuum you pair it with rather than an onboard bag. Owners rate it highly for low vibration and finish quality; the trade-offs are the small pad, the need for a separate vacuum, and grip paper in a less common size.

Questions and answers

Is the DEOS 343XCV good for large flat panels?
No, its 3 x 4 in. pad is meant for trim, frames and detail work. For big flat surfaces a 6 in. random orbital sander covers ground faster.
Does it collect dust on its own?
No. It is central-vacuum ready and needs a vacuum hose connected to capture dust. With a good vacuum, owners report strong pickup.
What sandpaper does it use?
3 x 4 in. grip-backed paper with a multi-hole pattern. The pad's hole pattern must line up with the paper for dust extraction to work.
How does it compare with a pneumatic detail sander?
It plugs into 100-120 V power instead of needing an air compressor, and its brushless motor holds speed under load. It is heavier than some air units but needs no compressor.
Can the speed be adjusted?
Yes. Variable speed spans 5,000 to 10,000 orbits per minute, so you can slow it for finish work and speed it up for stock removal.
What is in the box?
The sander and its 3 x 4 in. backup pad. Abrasives and the vacuum hose are sold separately.
