Review on 🔩 Fisch FSF 134893 High-Performance Drill Bit by Kaveen Reyes

I bought these to make clean, accurate and burr free holes in an ABS electronics enclosure and was not disappointed. At low RPM and gentle forward pressure, the resulting finished holes will be pristine, leaving a sharp and stress-free edge at the point of entry (start drilling from the front of the material, not the back).
