## Questions & Answers

**Q: Do they have a hex shank?**
A: So I am not sure of the brand as the box does not give that information but mine were 32mm and had 3 flats ground into a round shaft, perfect for very positive attachment to a drill chuck. I use them dry to drill conduit holes in cement blocks. They work great though they are a little shallow so I chipped out the core to go deeper.

**Q: In what country are these made?**
A: China.

**Q: Is the circle that remains after drilling still usable? I need to be able to use the circles. Thanks!**
A: I was drilling into wine bottles.

**Q: What is the warranty on these bits?**
A: No warranty. Because the masonry hole saw is a one-time drilling tool and doesn't provide warranty service. On the other way, it is recommended to add water during the drilling process, to extend the life of diamond hole saw.
