Rated 5 out of 5 by from Really handy As a self employed plumbing and heating engineer I use cutting tools quite a bit. This is one of the most handy pieces of kit I’ve bought in a while. Highly recommend. Shouldnof bought one years ago.

Rated 5 out of 5 by from Great Grinder Already had the Bosch charger and a jigsaw which work well. The grinder is the same last ages and works just like a mains powered one.

Rated 5 out of 5 by from Bosch User Having other Bosch units and batteries to spare, and needing a cordless grinder, this was a logical choice; a Google search showed I could get the item instantly from stock at Screwfix and as ever at a stonking good price. The performance is exactly as expected from a company that makes its products for the end user rather than its accountants.

Rated 4 out of 5 by from Great machine Fantastic grinder for the money, loads of power, as much as any 240v grinder I’ve owned. As others have said, it does eat batteries though. I have 2 4ah batteries for my 18v Bosch drill, & I started off using those, but when using both machines at the same time I came unstuck with not having a spare pack. Ended up buying a 3ah Bosch battery pack as a back up, and that’s where my only complaint comes in. Bosch batteries are by far the most expensive in the Screwfix catalogue, dearer than de-Walt or erbaur. I Would have liked a 4 or even 5ah as spare , but cost-wise could only justify the smallest cheapest one. That’s my only beef with the machine though, otherwise it’s easily up to any job I’ve thrown at it so far. Had it 2 months now, given 4 for reliability based on other Bosch machines I have.

Rated 5 out of 5 by from Angle grinder Fantastic grinder fast and powerful. Used for cutting trunking basket and tray amongst lots of other uses. Only real downside is it eats your batteries just make sure you always have one on charge and no problem.

Rated 5 out of 5 by from Great Grinder Great Price for a Bare unit. I’ve used it for cutting down steel unistrut and medium gauge galvanised steel tray and it cuts like a knife through butter. Lasts most of the day on a 4.0AH 18-Volt battery, so it’s great for sites without 110v power. Ideal if you already have a bunch of batteries. I bought this with the Bosch cutting disks and it’s worked like a dream. Would recommend and purchase again in a heartbeat. Can’t comment on reliability as I only got it a week ago but so far so good.
