I reviewed this 5 weeks ago, here it is again. Nothing has changed, I have not had to use it since. The 22mm x 300mm Diamond Core Drill Bit Hole Cutter for Brick Block Concrete is as described. It fits a drill with a 1/2" capacity chuck. It has its limitations. Because there is no pilot drill to position it in one spot to begin drilling, I had to use another 22mm TCT hole saw which has a pilot drill. Once I had cut a hole about 25mm deep using the TCT hole saw, the Diamond Core drill bit successfully cut further into the brick, creating a fine brick powder residue. Is it good quality? I'll say Yes at this stage but I don't know how it will perform on future occasions. Although I had to import it into Australia from the UK, with all that extra postage charges, I consider it was well worth it because I couldn't find any 22mm hole saw in Australia suitable to cut through the full width of a house brick. it did the job i needed it to do.Read full review
