Is the DWE4120N good for cutting steel?

Yes. The 9 amp motor at 12,000 rpm handles cutoff wheels on steel and rebar well. Use the correct wheel and guard for cutting.

Does it have a variable speed dial?

No. It runs at a single 12,000 rpm speed. For variable speed you need a different model.

It takes 4-1/2 in. wheels with a 5/8 in. to 11 spindle thread, which covers most grinding and cutoff discs.

What comes in the box?

The grinder, a one-touch guard and a hex wrench. Wheels and the side handle are listed separately by some sellers, so check before buying.

How does it compare with the DeWalt DWE402?

Both are 4-1/2 in. grinders with similar motors. The DWE4120N adds the paddle switch and Quick-Change wheel release; the DWE402 uses a slide switch.

Is it safe for one-handed use?

The paddle switch stops the tool when you let go, which helps. DeWalt and safety guidance still call for two hands and the side handle where possible.
