Premium Dry Diamond Core Drill 38 x 170mm is rated 4.6 out of 5 by 56.
Rated 4 out of 5 by from Does This core drill cut through a cavity wall of brick and breeze block easily and quickly, don’t forget to start drilling from the outside to avoid damaging face work

Rated 4 out of 5 by from Did the job. First time I've used a diamond core drill bit. I used twitch a Bosch professional GbH SDS drill to cut a ventilation hole in an external garage wall- breeze covered in thick concrete/pebbledash. Chiseled out the pebbledash first then cut through from either side. Very glad I had a drill with a mechanical clutch, as it certainly tends to seize up as the depth increases and the angle changes slightly. It cut the hole (slowly) without gentle pressure. So- pretty good in my limited experience.

Rated 5 out of 5 by from all good... did a good job being that bit larger than the 152 norm gave a bit of play which helped a great deal

Rated 5 out of 5 by from Cut well and the size was perfect I got this as a lot of 6” extractor vent kits are actually bigger than the 152mm core drill I normally use so got this bigger one and it was the perfect size.

Rated 5 out of 5 by from Great core drill for tidy job. Core drill did a good job on hard brick for 40mm waste pipe. Gentle pressure and slow rpm took about 5 minutes. Pipe OD was about 43mm and the hole was great for setting an elbow inside the wall.
