A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these machines answer different questions.
Which of the two, for which metal
Buy the DWE4057
Buy the DEWALT if tools live plugged in on your bench. Restart protection stops a switched-on grinder coming alive when power returns, and soft start removes the twist at switch-on.
9558NBRZ
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Buy the Makita if your work is filthy. A labyrinth seal keeps abrasive dust out of the bearings, and abrasive dust is what kills grinders that are otherwise fine.
The questions welders ask
Which risk is more common?
Both are ordinary. Grinders left switched on and plugged in are extremely common in home workshops, and so is a machine that develops a rumble after a season of rust removal. If you must pick one, restart protection prevents an injury and sealing prevents a purchase.
Neither has a brake — how much does that cost me?
Five to ten seconds of spinning disc after every release. That window is when people set the tool down, reach across it or let it hang beside a leg. Machines with brakes start around €200 on this site, and one publishes a 3.5-second stopping time.
