DeWalt D28113-GB 4½" Angle Grinder 230V 4.6 5 29 30
Poor reliability Good points are that it is comfortable to use, powerful and gives clean cuts. I use angle grinders on a daily basis for around 3-4 hours, I cut steel up to 1/2" thick, then de bur and polish. I also use it for shaping wood and large stock removal. I work them hard and this just died after 6 months. Back to dewalt for repair and a loss of 7 days working. Touted as a 'heavy duty trade' tool this certainly does not live up to the hype. Bosch pro lasted 12 months! I'd never use a Dewalt again, just a jumped up B&D. I had to buy another so I plumped for Makita! Never even got to use that, the switch fell off before I used it....just going to get a Metabo. 22 Jun 2015
Used for very dusty work Used this to grind down and smooth out concrete walls and floors, so an extremely dusty environment, but worked very well and didn't fizz on it. Comfortable to hold and seems to have plenty of power. Very pleased with this grinder. 15 Jun 2015
Great piece of kit Very comfortable to hold (anti vibration handle) and very powerful for its size. With diamond disc it cut through slabs like a knife through butter. Very pleased with my purchase. 4 Jun 2015
Grinder getting HOT ! Dewalt D28113-GB 4 1/2" grinder. Having only used it a few times (cutting some 15mm copper pipework), I've noticed that the grinder has quite HOT. Is this normal ? ...I don't recall my previous grinders getting as hot after only so little work. I am considering returning it as being faulty but thought I'd ask you good folks for your thoughts. Also extremely disappointed that it doesn't come with a case. I have since found out that a Dewalt d28113-K is grinder complete with kitbox (case). Shame Screwfix don't sell a complete kit. :( 31 May 2015

Having only used it a few times (cutting some 15mm copper pipework), I've noticed that the grinder has got very warm.

Is this normal ?

... as I don't recall previous grinders get so warm after only so little work.

I am considering returning it as being faulty but thought I'd ask you good folks for your thoughts first.

Hi there, This is a potential fault with the tool as it shouldn't get that hot that quickly, but then there are plenty of factors that could cause this, what disc are you using, and the angle you are cutting, or even where you are holding the grinder could be a factor.
If you live near a repair agent then you can pop in and get them to inspect the tools to find out if there is a fault or depending on the when you bought the grinder you could potentially get your local Screwfix store to send it back to us to inspect the grinder as long as it is within the 1st year warranty?

If you use this link and input your post code it will bring up a list of your local service agents.
