Work in most types of block and brick even without using hammer action. ### ⭐⭐⭐⭐⭐ Excellent drill bits *by R***S on Reviewed in the United Kingdom 🇬🇧 on 1 January 2021* I like Heller drill bits, always use them. My son borrowed mine and I didn’t see them again, so hence I bought some more. They are well made and do an excellent job. I don’t think you can go wrong using them. ### ⭐⭐⭐⭐⭐ Good quality drill bits *by M***C on Reviewed in the United Kingdom 🇬🇧 on 1 May 2019* Just what was required for jobs at home.
