These are great little kits if you have a lot of core drilling to do through any sort of masonry.
I picked up this set to install some extractor fans and a couple small 40mm waste pipes and they worked a treat. At this price they dont break the bank and it saves the relationship with your mate who has a set and who you constantly pester to borrow them from..
I dont use the special core drill for these I just have my standard masonry drill, you will just need to make sure its a geared drill so it doesn’t snap your wrists when the drill bit locks in the hole..
