My Final Opinion of Dewalt cordless angle grinder

The Dewalt cordless angle grinder is a handy tool to have,being cordless is get rid of the need to find an output and it has enough power to do the job. The only problem is its length so if you need to get into small confine spaces regularly then you might consider a smaller angle grinder.

On the Dewalt page this angle grinder has 197 reviews at time of writing and a score of 8.9 out of 10. So a lot of people like this machine.

What others have to say:

“Grinder is a superb machine as you would expect from dewalt.
The rpm at 7000 is slower than a mains machine but perfectly adequate to do the job.
I cut 4 lengths of conduit, 6 cuts of 25x 5 mm bar some hollow tube and a 15 x 15 bar and used a third of a 4 ah battery and about 3 mm of a disc, let the machine do the work.
No worries at all about battery or disc life”

and another:

“As I had the 18v twin set 4 ah I decided to add this to my collection. I put a good quality diamond disc on and expected to use it for the odd cut. However it is surprisingly powerful and cuts through roofing tiles easily. I have also used it for cutting off metal bolts which it does easily. The battery’s last longer than expected but you want at least two ideally three if you have a lot to cut . I hardly use my dewalt 115mm corded grinder unless I have a lot to do or grinding out pointing. Get one you won’t regret it”
