Extremely soft. Failed to drill through annealed 304 stainless steel. Clearly rounded tip. When sharpening, the material is removed too easily. Must have been a bad batch.
I'm always looking for those shiny finish drills because the coating on some drills leaves a lot to be desired in terms of cutting ability and accuracy. These bits work perfectly in small projects where accuracy is of the utmost importance.
The drill bits shipped in the manufacturer's packaging were incorrect. The drill bits I received were "jobber" lengths, not "screwdriver" lengths. It looks like the error is NOT related to Revain as the packaging correctly lists the type of drill ordered. It only contains the wrong drills.
