Premium Dry Diamond Core Drill 38 x 170mm is rated 4.7 out of 5 by 7.
Rated 5 out of 5 by from Cuts well Use a pilot bit or freestyle if you're not bothered. It does the damage anyways and bore a nice hole. Can be tricky to get brick out of the core bit if it breaks into pieces

Rated 4 out of 5 by from Tough item in a Flimsy Box I used this to bore through a 180 year-old concrete slab, about 10" thick. The bit held up well and went through without binding or clogging. This was a vertical hole drilled from above so the weight of my 6.5kg SDS drill was enough to drive the bit through and I stopped every 20 seconds or so to remove debris, which was a mixture of dust, chips and a small plug, which was easy to remove from the bit by prodding a screwdriver through the vents. After the job, some wear was evident on the bit but there were no chips or scores and it's got enough life for a few more similar jobs. The bit, along with the arbour and Titan drill to drive it, cost less than I was quoted to get someone to drill it for me and I've got some useful tools to add to my kit. I have similar tools that came supplied in plastic cases to protect them for future use. If this came in a sturdier case than a simple cardboard box it would've been 5 stars.

Rated 4 out of 5 by from Core drilling drainage holes in retaining wall 20 drainage holes to drill. 10 done and the core bit is still going strong. Good value

Rated 5 out of 5 by from Great piece of kit I was having difficulty creating a hole for 40mm waste through a cavity wall so purchased this. Worked a treat. It grinds rather than drills with minimal dust. I had to draw it back and forth in order to widen the hole enough for the pipe but this was no challenge at it ground the brick away quite easily. The only negative is that it is not long enough to go through a cavity wall so you may need a long masonry bit to give you an idea of where to grind from the other side.

Rated 5 out of 5 by from Knife through butter! Product had clear instructions. Just remember to use a decent drill preferably with clutch, SDS & power min 900w.

Rated 5 out of 5 by from Quality Item Purchased this to bore hole through engineering bricks, although it states dry cutting I did apply water due to hardness of material to cut, It cut several holes no problem.
