Our take on the DeWALT DWE402K 4-1/2" Wheel Diam, 11000 RPM, Corded Angle Grinder

The DeWalt DWE402K is a corded 4-1/2 inch angle grinder with an 11 amp, 120V motor that spins at 11,000 RPM. That combination puts it among the more powerful grinders in its class, where many rivals run 7 to 9 amps. It suits metalworkers, welders and contractors who cut and grind steel all day and want a tool that holds speed under load. The trade-off is weight and corded-only use, so it is less handy for quick overhead jobs than a smaller or battery model.

Questions and answers

Is the DWE402K powerful enough for cutting steel?
Yes. Its 11 amp motor and 11,000 RPM top speed are above most 4-1/2 inch grinders, so it cuts and grinds steel without bogging down much.
Does it have variable speed?
No. It runs at a single top speed of 11,000 RPM with no speed dial, so it is built for full-speed cutting and grinding rather than polishing.
What wheels does it take?
It uses 4-1/2 inch wheels with a 5/8-11 arbor, the common size for cut-off and grinding discs.
Is it good for one-handed use?
It can be used one-handed, but it is heavier than compact grinders, so most owners use two hands for control and comfort.
What comes in the box?
The kit is sold with the grinder, a side handle and a wheel guard; discs are usually bought separately.
How does it compare with a cordless grinder?
It delivers more sustained power than most 18V or 20V cordless grinders and never needs a battery, but it requires an outlet and is heavier.
