- Size: 4 ½ inch
- Speed: 11,000 RPM
Many professionals prefer a corded angle grinder over a cordless one for its power. Dewalt DWE402 boasts a powerful 11-amp motor and a maximum working speed of 11,00 RPM for the best available power-to-weight/size ratio.
This 4 ½-inch angle grinder can be used for numerous demanding jobs like grinding and beveling steel or repairing and preparing concrete surfaces. It is compatible with all 4 ½ discs with an arbor size of 7/8 inch.
Crushing or grinding concrete generates a lot of silica dust, which can seriously contaminate the air, causing fatal respiratory diseases to humans. Just like wearing a protective mask for yourself, you should also protect the grinder’s motor from possible damages resulting from dust.
Thanks to the Dust Ejection System, the motor and internal electrical parts will be kept from dust and debris particles. In other words, you can use this grinder for a more extended period with less wasting time for brush motor replacement and repair.
Since it comes with a One-Touch Guard, you can easily rotate the guard at any angle that is best comfortable for you. You don’t have to remove the guard (which is dangerous for you while working with complex and sharp materials) or force yourself in a weird guard position like other cheaper models.
Pros:
- Its powerful motor provides 11,00 RPM
- 2 removable side handles

When repairing your walkway or driveway, you will need an angle grinder to cut concrete pavers. A circular saw with a blade for concrete can do this job, but it can’t get it done with high precision than a grinder.
A cordless, lightweight grinder like Dewalt DCG413B is the best candidate for that type of job. It offers ease of use and portability while working with demanding jobs like fixing roads.
The first notable advantage is that it operates on a brushless motor. Its motor type has more PROs than a brushed one, including low maintenance cost (no brush change), low vibration and noise, high efficiency, higher durability. Although it can cost you more at first, you will have to spend less money on maintenance and care in the long run.
Besides, it uses a 20V Max Lithium-ion rechargeable battery (the battery and the charger are sold separately). If you have another Dewalt tool that also runs on this battery type, you can utilize it without spending an extra budget for the battery.
Along with its stunning performance, this Dewalt angle grinder also offers you many safety features to protect you, the tool, and the wheel from possible accidents and damages.
For example, if there is an unexpected electricity shutdown, you need to cycle the E-Switch again to run the tool. Plus, the built-in Kickback Brake quickly stops the wheel and the motor as soon as it senses something dangerous, like meeting a more rigid surface than its capability.
