Guide Review - Porter-Cable 343VSK Random Orbit Sander Review

The Porter-Cable 343VSK Random Orbit Sander makes quick work of sanding tasks. The sander isn't overly noisy, and the dust collection system (whether using the canister or connected to a dust collector or shop vacuum) works better than I expected.

To test the 343VSK, I sanded a rough-cut board using progressively finer sanding disks, beginning with 50-grit, working through 80 and 120, and finally finishing with some 220-grit disks. After completing the sanding with the 220-grit disk, there was very little sawdust on the board or the table beneath, yet there was a considerable amount inside the dust canister.


There were only two things that I didn't like about the 343VSK, and one of them probably qualifies as "nit-picky." Longtime readers of this space are well-aware of my dislike for map-style instruction manuals, that must be folded out onto an open table space in order to read properly. I know this is probably a less expensive way to make an owner's manual, but I really don't like having to clear table space in order to look up something quickly in the manual.

The more tangible issue that I had with this sander was that, particularly when using heavier-grit sandpaper, I really felt like I was getting a bit of a workout. To keep the sander on course seemed to require a bit more muscle than I expected. That's not necessarily a bad thing, because it is the aggressively fast sanding action of the 343VSK that requires more muscle to keep it where I want on the work surface. It's just something you should keep in mind when choosing a random orbit sander, especially if you have a lot of sanding to do.

I know that working with this sander for an hour or two would probably get the job done quicker than comparable models. I also know that I'd probably feel it a little more the next day than with comparable models.
