🔨 Drilax Diamond Concrete Masonry Cutting Tools: Industrial Drill Bits for Precision and Efficiency Review

This bit is a perfect match for my 3/8" drill. I used it to make drainage holes in 2 very large concrete pots. The bottom is 2 inches thick and this columnist completed both in under 10 minutes. I kept a stream of water from a garden hose on my work surface and a freshly charged battery in my small 12 volt drill. I only drilled those 2 holes with it so I can't speak to strength or durability. But it looks pretty good after punching through those massive pots.

I bought this item because I couldn't find it at my local hardware store to drill holes for plumbing going through the hollow concrete block wall in my house. Backyard. After successfully drilling three holes and partially through the fourth, about half of the "teeth" broke off. I couldn't continue and had to hope it went far enough to tap on it with a hammer to finish the job without destroying the whole block. This article is now in the trash where it rightly belongs!

So I bought this to just drill 2 holes to run plastic pipe for connections to my garage to perform . ......It's Chinese crap so I wasn't expecting much but I figured he should be able to handle the two holes I had to drill but he couldn't complete the task... By the time I was finally able to finish the second hole I had basically punched this bit through the last remaining 1/2 inch leaving only a partial edge of the diamond dust bit……So kind of worked but mediocre quality at best
