Review: Great value and does the job - For the price, this is a great set of bits. I only needed the 40mm core drill to go through a solid brick pier 350mm deep. It took about an hour but the drill eventually went through. I had drilled a pilot hole with an 8mm long masonry drill to act as a guide. It's not clear but the set comes with a grub screw and a hex bolt to secure the guide drill. I used the grub screw with some Loctite and it didn't come loose as some have reported.

Did the job, cut through brick work with ease

### ⭐⭐⭐⭐ Great product, BUT...
*by A***X on 2 January 2022*

Bought this as I needed to drill a hole through an old 50's built council house double skin brick wall to put a waste pipe through. Knew the bricks were hard, but reviews on this were OK so thought for the price it was worth a go! Worked really well! 40mm hole at slight angle through both skins in about 20 minutes. BUT... only problem is that the bolt that secures the guide bit kept coming loose, and eventually came out and disappeared into the cavity between the 2 brick walls :/ No major drama as I was nearly all the way through by then so just took the drill out for last little bit, but not ideal, hence a star off. Just need to establish what size replacement bolt I need and will grab a few as fully expect to loose more. All in all, a pretty good set and hole saw seems to have not degraded after use so far.
