Topic tags/keywords: tool twist reamer dynamite

Hi All,

Ran across these two in one of my Dads many tool boxes. He does not remember where they came from.
Sure, they are reamers, or drills? But how come the points are do dull, not sharp at all. The tip angle is very low. It would take a whole lot of work to make a hole with these. And why possibly would they both have “do not use for dynamite” on them?

Thank you,
Eric O

We have a winner from ChuckV! It is a coring tool for blocks of plastic explosive (which is NOT nitroglycerin based dynamite). Fed that info to my Dad (92 years old), he remembered that he got them from an army surplus store. No idea what to do when them, other than put them in that drawer of funny and one of a kind tools.

If no one winds of knowing what they are, you could try loaning or sending the picture of it to Tubalcain Youtube guy (MrPete222) for his what is it mystery tool series of videos.

Maybe rock drills of some sort for doing
cleanup work by hand.

Putting a hole in a stick of dynamite I think
you’d want to use something non-ferrous.

Those are curious tools.
In that fresh and properly stored dynamite is not set off by sparks or flame (it will only burn) and needs a “concussion” from a blasting cap or similar action so it is hard to understand why the tools are labeled that way. I’m looking forward to you finding the answer.

Just a general comment on dynamite. It is obviously hazardous because it is made with nitroglycerin (a syrupy liquid) that has been added to an absorbent material like sawdust or diatomaceous earth. With improper storage the nitroglycerin can slowly seep out and become very unstable; especially in warm/hot conditions (it needs a dry cool place and must be psyically rotated regularly). At the point it starts to weep a physical shock can set it off. Disposal of old dynamite is usually done (by experts) by burning it.

They don’t want you to try to blow something up with it, just in case you were thinking it was dynamite.
Everybody has to put a disclaimer out these days.

You just know somebody tried to blow up a bank safe with one, and it didn’t work, so they sued the company.
