Is this grinder worth it over a 4.5-inch model?

Only if you cut or grind large areas of concrete, masonry or steel. A 4.5-inch grinder is lighter and cheaper for general work, but a 9-inch wheel cuts much deeper in one pass.

Does it have a lock-on trigger?

No. The switch is a trigger type with no trigger lock and no lockable switch, so you keep pressure on it while grinding.

What wheels does it take?

9-inch Type 27 wheels with a 5/8-11 arbor. That spindle size is standard, so most grinding and cutting wheels for 9-inch grinders fit.

What comes in the box?

Each grinder includes a wheel guard. The listing is a six-pack of grinders, so expect six units.

Can it run on a standard 120V outlet?

It is a 120V, 15A tool, so it needs a circuit rated for 15A or more. Long extension cords should be heavy gauge to avoid voltage drop.

When is the price lowest?

Bulk tool packs tend to drop during contractor promotions and end-of-season sales. Check the price history before buying six at once.

Our take on the DeWALT 9" Angle Grinder

The DeWALT 9-inch angle grinder is a corded 120V heavy-duty tool with a 15A motor rated at 4.7 hp and 6,500 RPM. It takes 9-inch Type 27 wheels on a 5/8-11 spindle and has a trigger switch with a wheel guard included. It is a large two-handed grinder built for cutting and grinding concrete, masonry and steel, not for light shop work. The listing is for a pack of six grinders, so the per-unit cost is the number that matters.
