Fine but easily snapped.
These worked fine for a one time job of drilling into a lock, but they all broke at the tip. This added to the time for the job as the tip then had to be retrieved in order that it wasn't an obstruction. My advice, if you are using these for metal, buy a pair of fine straight tweezers at the same time, to get the broken tip out quickly.

Made the job easy
Perfect, did the job that was put on hold because the other drill bits I ordered were useless. These drill bits drilled the holes easily, and I did the job in a few minutes. I'm going to buy the next sizes up for my toolbox. Highly recommended.

Good drill bits, more for aluminium than steel
Good drills for ally, but I had some 2mm steel plate to go through and by the time I had put in four holes, one of the bits was pretty shot by then.
