The DEWALT DWE402 is a 4-1/2-inch (115 mm) small angle grinder engineered for grinding, cutting, and surface prep on metal, masonry, and more. Its next-generation 11-amp AC/DC motor delivers 11,000 rpm, giving you strong performance in a compact, ergonomic body. The paddle switch provides instant start/stop control, and the overall design reduces fatigue during extended work.
The Dust Ejection System keeps damaging dust and debris from entering the tool, while the One-Touch guard rotates 360 degrees with a single action. The Quick-Change wheel release lets you swap wheels without a wrench. Over-sized brushes last twice as long as the previous D28402 model, and the large spiral bevel gear extends transmission life.
If the guard feels stuck, first make sure the grinder is unplugged. Rotate the guard lever and press the One-Touch button; if it still won't turn, check that no debris is wedged around the guard ring. For a DWE402 guard removal, loosen the guard clamping screw only enough to clear the locking tab, then rotate the guard past the stop. Never operate without the guard. Full instructions are in the DWE402 manual. The DWE402 is a favorite among contractors and DIYers who want a dependable, serviceable 4-1/2-inch grinder without moving up to a larger 5-inch tool.

The DEWALT DWE402 is more than just a powerful angle grinder; it's a tool that resists the two things that kill grinders: heat and contamination. The Dust Ejection System and large spiral bevel gear keep it running smoothly on jobsites where dust is everywhere. The One-Touch guard is a real time-saver when you switch between cutting and grinding positions.
For cutting metal, use a thin cutoff wheel. For surface work, use a grinding wheel or flap disc. The 4-1/2-inch size gives you a good balance of reach and maneuverability. Always check the wheel's RPM rating to match the grinder.
The paddle switch gives you full control instantly, and the narrow grip zone makes it easier to hold and guide. The tool is about 1.5 inches shorter than many older grinders, which reduces fatigue and improves visibility when you're working tight to a surface.
Make sure the grinder is unplugged. Rotate the guard lever and press the One-Touch button while turning. If it still doesn't move, inspect around the guard ring for debris or damage. Refer to the manual for proper guard adjustment.
Unplug the grinder, loosen the guard clamping screw, and rotate the guard to the release position. Carefully slide it off. Always reinstall the guard before operating the tool.
It accepts 4-1/2-inch (115 mm) wheels with a 5/8-inch arbor. Use the correct wheel for the material and check the rated speed.
Yes, use a diamond or abrasive cutoff wheel rated for masonry. Always use the guard and wear appropriate PPE.
It uses the grinder's fan to eject dust and debris before it enters the tool, extending the life of the motor and switch.
Beast.
This grinder is amazing. The paddle switch is convenient. It cuts through metal easily.
I've used grinders for 30 years. This is my favorite. The dust ejection system keeps the motor clean. The One-Touch guard is really handy. It's well balanced. I use it every day.
It's heavy but does the job. The trigger is smooth.
Lots of power. The paddle switch is a safety plus. I like the tool-free wheel release. Very solid.
I use this for sharpening tools. It does a good job. The guard is easy to adjust.
Great grinder. No complaints.
I bought this for my husband. He loves it. He says it's the best grinder he's owned.
This grinder is a monster. I've abused it for years and it still runs perfectly. The dust ejection really works. Excellent tool.
It works but the paddle switch is hard to press if you have small hands.
No issues. Value for money.
