Why not snip the pin on both sides with wire cutters? If you want another hole for effluent, poke it again in a pleurite.
I assume this is for non-destructive extraction from a small beetle, so it can be pointed after extraction and drying. Or you can leave some of the pin underneath for a double mount.This electronic message contains information generated by the USDA solely for the intended recipients.

A student wishes to place dried specimens in a solution which will extract the body contents for DNA extraction. But needs to remove the pin first. I have read about techniques that can heat a pin using a battery system allowing the pin to be removed- but have not seen one in action! Someone else has suggested that a drop of 'wood naptha' at the base of the pin would relax the specimen locally and allow the pin to be removed.
