Review: Solid bits - These are great. I used them on a job today to drill a hole in some travertine. They went through it like butter. They also didn't blow the back of the stone out when it went thru. Definitely worth the money.
Review: Bomb shelter bricks - I've got a home which I swear was bricked up with bomb shelter rated bricks. I've never had to deal with drilling into anything like it. I used the largest hole saw of the set for installing a new sump pump outlet through the basement rim joist and outer brick. It took me a good 15 minutes to get through it, but this set did fine. As to the bolt and the pilot drill, frankly I don't like keeping them in anyway. Once the hole saw starts biting enough of a hole that it can self guide, I remove the pilot bit, so no issue with the bolt shaking loose. It did the job I needed it for, and the carbide looks fine. I don't doubt that it will last quite a while. The only issue I did run into was after I finished, I did not take the whole saw off the shaft and just chucked it to the side. Methinks it would have been better to pop it loose while it was hot. At this point it's stuck, but I figure I'll just hit it with a torch and break it loose.

### ⭐⭐⭐⭐ Worked well.
*by F***O on March 18, 2025*

I needed this to bore 2 one-inch holes thru the concrete block wall of my house to install a water softener. The first hole passed thru the "hollow" portion of the block and the tool cut thru both sides well and made a fairly neat hole. The second hole lined up with the web in the center of the block and took much longer. But the tool did the job and continued to cut straight. I did have to stop and re-tighten the pilot drill a couple of times and the shank did loosen up in the chuck as well. The tool looks to be in good shape after boring two holes. The only reason I didn't give 5 starts is that I've never used anything like this before and have nothing to compare my experience to.
