The full read
The Porter-Cable 7346SP is the polisher you learn on and then keep out of loyalty. Six-inch platform, variable speed, and a random-orbital action forgiving enough that a beginner can lean on it without burning a panel — the dual-action motion is what keeps you honest while your technique catches up. It's the machine the job site reaches for when the Festool is still sitting in the truck, and it never once complains about the demotion.
It won't flatter you the way a pro tool will; it's mid-tier and content to be. What it offers is a wide, stable footprint, speeds you can actually dial in for the job, and a price low enough that a mistake costs pride instead of rent. The dust canister on the sander variant earns its keep too, pulling enough to keep the surface readable while you work.
Buy it if you're getting into paint correction and don't want to gamble real money on the first try, or if you want a rugged second machine that lives in the truck. Skip it if you've already got a DEROS and standards to match — this one gets the job done without commentary, and sometimes that's the entire point.
Use it when
The fit is obvious.
- · Reach for the Porter-Cable 7346SP Sander when the job is job site, large flat surfaces, and budget home shop — that is the fight it was built for.
- · Reach for it when you plan to run one tool through discs, pads, and compounds across a whole progression.
- · Reach for the machine when the surface is big enough that steady pressure and honest repetition beat hand feel.
Skip it when
The job asks for something else.
- · Leave it if a simple hand setup finishes the work before the tool is even plugged in.
- · Leave it if you already know you want the premium option; a mid-tier pick is a compromise, and you clearly are not in the mood for one.
- · Leave it if the job is tiny, edge-heavy, or too irregular for a machine to help more than it hurts.
