Features

  • Brushless motor of the angle grinder requires no brush changes.
  • DEWALT grinder's brake stops wheel in 2 seconds or less on average
  • Kickback Brake engages when a pinch, stall, or bind-up event is sensed and the electronic brake engages with maximum force to quickly stop the wheel, reduce the movement of the metal grinder and shut the grinder off.
  • Features E-Switch Protection - When the ON/OFF trigger switch has a no-volt release function. In the event of a power outage or other unexpected shut down, the trigger switch will need to be cycled (turned off and then on) to restart tool.

Description

This brushless small cordless angle grinder requires no time changing brushes, and offers a longer motor life. DEWALT cordless grinder offers a high level of protection. Its break stops the wheel in 2 seconds or less. The Kickback Break engages maximum force to stop the wheel when there is a pinch, stall, or bind- up to reduce kickback. The grinder will also shut off in those events to further protect the user. Battery and charger are sold separately.

  • Best grinders on the market for design, build, quality and cost. Love Dewalt!!
Size: One Size Style: 20V 4.5IN Grinder
Doesn't get better than Dewalt. Dewalt always tops my list of well designed, well built equipment that's affordable for the DIYer as well as the professional. Balanced perfectly in my hand, which tends to be on the smaller side. Because the size and weight are so well thought out, the added layer of safety is a given. I've wanted a grinder for a while, so when I needed to strip down the rv gate, this was a no brainer. I had initially started stripping it down by hand, but gave up after a couple of hours. I finished stripping the whole gate in a day once it was delivered. Have the right tool makes a difference. Having the best tool is just smart! I'm sure I will be using it for many more projects because the additional wheels you can change out makes this especially versatile. ... show more

  • Powerful and Easy to Handle
Size: One Size Style: 20V 4.5IN Grinder
Excellent tool. It has plenty of power for cutting and grinding metal, the battery lasts a long time, and the brushless motor feels very efficient. It is comfortable to hold, and the build quality is exactly what you would expect from DeWalt. I highly recommend it for both professional jobs and demanding home use ... show more

  • No Regrets, good tool.
Size: One Size Style: 20V 4.5IN Grinder
This thing works great. I put off buying one for years and I can honestly say I should have bought one sooner. I did buy a $40 corded (Bosch I think?) one slightly before I bought this and it worked great as well but having a cord sucks and I didn't like the power switch. The Dewalt just feels more comfortable to use in most cases. If you're on the fence I would say this is worth it over one with a cord if you're not going to be going crazy for hours cutting things. I use it with a cutoff disc and just keep a grinder on the corded one I have now. The attachment mechanism does make it easy to swap discs though so if I didn't have a second grinder it wouldn't be a big deal changing back and forth. ... show more

Very useful tool! It is made well. I didn’t have any problem attaching different blades.

  • No wrench included. No wrench included.
Size: One Size Style: 20V BL 4.5IN Angle Grinder
Great little grinder. Cut 1/2” rebar easily. Only got 4 stars because wrench was not included. Guy at Dewalt said they don’t supply this part. How are you suppose to tighten blades. They did include an Allen wrench. Could not figure what it was for.

Cuts not as much power cutting as corded but it works fairly quickly.

  • RV Workshop Essential – Powerful and Safe Cordless Grinder
Size: One Size Style: 20V 4.5IN Grinder
RV Workshop Essential – Powerful and Safe Cordless Grinder Used this DEWALT DCG413B on my F250 and RV projects for cutting steel brackets, grinding welds, and smoothing concrete edges—the brushless motor delivers strong 9,000 RPM and the kickback brake stops the wheel instantly if it binds, adding real safety. At just 3.75 pounds, it’s easy to handle for extended use, and the paddle switch feels natural. Only drawback: battery life is limited for long grinding sessions (20-30 minutes on a 4Ah pack), so I keep a spare charged. If you’re already in the DeWalt 20V ecosystem, it’s a fantastic, portable addition; otherwise, factor in battery/charger cost. ... show more
