UK Drills Diamond Core Drill Bit 32.0 mm x 150mm, Laser Welded - To Be Used in Granite, Concrete & Masonry

Happy with my purchase

Made a vent hole in a very thick wall- hard work and messy job but well pleased!

If you want a set of cores to last a while these are probably not the best bet. You get what you pay for. I'm not knocking the product down at all it's ok value for money but in hindsight I wish I had just spent a bit more on a better set. Oh and the case is pretty ridiculous. it's basically the size of a small suitcase with wheels and a pull out handle.

Used core bit worked flawlessly with extension still got lots of life left went through inner and outer wall no problem price about right

The diamond drill core completely broke off from the base and became useless after a few uses on soft concrete blocks.Wouldn't buy it again!!!

I was a bit sceptical about this (based on the price compared to Toolstation/Screwfix etc) but I only needed it for one job so I didn't want to spend too much.I am extremely pleased to be proven wrong.This bit has cut its way cleanly through a two brick thick 1920's wall (proper bricks!) even using my 18v cordless sds drill. It never jammed, it cleared the dust and debris perfectly well. I am confident that with a bigger 24v/110v site drill this would be like a hot knife through butter.It's definitely £20 quid well spent.

As described

Did the job, nothing more to add
