A: Hi Tony! We would recommend using the DBDS45045101F. It has longer life than the above disc due to its special ceramic blend as well as being a little ticker, which can help you when doing with something tricky like rebar where you can experience a wide variety of hardness’s depending on what metals were used in its creation.
