Overview

The DEWALT DWE402 is a corded 4-1/2 inch angle grinder built around a 1320 watt motor that spins up to 11,000 RPM. It runs on standard 120 volt power and weighs about 6 pounds, aimed at metal cutting, grinding and surface prep rather than occasional light use.

DEWALT keeps this model corded rather than cordless, which trades battery swapping for unlimited runtime as long as it stays plugged in. The 11,000 RPM top speed and 1320 watt motor place it in the small angle grinder class, suited to cutting, deburring and light grinding rather than heavy stock removal.

  • 1320 watt corded motor
  • 11,000 RPM no load speed
  • 120 volt standard power
  • 6 pound tool weight

Who it's for

Tradespeople and serious DIYers who need a full time grinder for metal work, welding cleanup or masonry cutting will get the most from this tool. Anyone who only needs an occasional light grinder or wants cordless portability should look elsewhere.

Pros and cons

Pros
  • Corded power avoids battery runtime limits
  • 1320 watt motor rated for regular metal work
  • 6 pound weight keeps handling manageable
Cons
  • Needs mains power, not for battery-only kits
  • Weight and speed suit smaller wheels, not heavy removal

Performance notes

Output on a grinder this size comes down to motor wattage and no load speed, and the DWE402's 1320 watt motor at 11,000 RPM is built to keep spinning under load rather than bogging down when cutting or grinding. Being corded, that power stays constant as long as it's plugged in, unlike a battery grinder that can slow as its charge drops.
