High-strength steel (e.g. 16MnCr5, 25CrMo4): Can be suitable with adapted process parameters. Some extreme types are not suitable. We’re happy to help you explore the possibilities.
Mild steel (S235): Commonly used in various applications. Frictiondrilling in S235 is no problem at all.
Stainless steel (304/316): Requires adjusted drilling parameters due to higher strength and heat generation. Local discoloration from heat is possible but can be treated with passivation techniques.
