Not sharp enough
Over heats quick

Does the job
Worked fine for me, as the hole to be enlarged was in fiberglass, therefore relatively soft. Not sure it would work as well with hard metal. The Automatic Spring Loaded Center punch is a convenient little tool to have

Low price - low quality
The quality is very low. Only suitable for plastic or very thin metal. But for such a low price, it's not bad.
