Is the DWE402W good for cutting metal?

Does it need a wrench to change wheels?

No. The Quick-Change release lets you swap wheels by hand. A wrench is included for the guard and flanges.

Is it corded or cordless?

It is corded and runs on AC or DC power, so it needs a mains outlet or generator.

What comes in the box?

The grinder, a one-touch guard, a two-position side handle, a wrench and a 4-1/2-inch abrasive wheel.

Can I use standard 4-1/2-inch accessories?

Yes. The matching wheel flanges accept common 4-1/2-inch wheels and accessories with a 7/8-inch arbor.

Is it too heavy for one-handed use?

Our take on the DEWALT Angle Grinder Tool, 4-1/2-Inch (DWE402W)

The DEWALT DWE402W is a corded 4-1/2-inch angle grinder built around an 11 Amp motor that spins at 11,000 RPM. It targets heavy material removal: cutting rebar, grinding welds and smoothing steel. Its tool-free Quick-Change wheel release, one-touch guard and low-profile gear case set it apart from cheaper grinders that need a wrench and a fiddly guard. Owners of the DWE402 line generally rate the power and durability highly, though many find it loud and heavy for overhead or one-handed work.
