What is this?

[Coggy CParticipant @coggyclapsaddle]

I bought a box of old cutters, bits and pieces from a boot sale and when sorting through it I found this below. Can anyone tell me what it is and what it's used for.

I appears to be some sort of cutter as it has sharpened edges on the sides and when rotated the two inside parts with the sharpened edges spin out.

I've never come across one before and I'm not even sure how or what it's used in or if it's complete.

I suspect it is for cleaning up a bore that has become scarred or encrusted with gunk. Bit like a reamer but not a defined diameter.

[Coggy CParticipant @coggyclapsaddle]

That would make sense, there is no way to fix/lock the outside width so I guess it's not a precision tool for a set diameter.

[John ReeseParticipant @johnreese12848]

It appears similar to a Madison adjustable floating reamer.

[Coggy CParticipant @coggyclapsaddle]

A floating reamer seems to be the answer. Thanks all, every days a school day.

Though I don't get how you would use it as not being a fixed diameter I would have thought the results would be variable.

Christmas teaser. What are these pliers. Bought from an iron mongers closing down sale. Google lens offers “Cork remover” but I think it may be from Thé tarpaulin/ canvas trade ??

for handleing small but hot pot or crucible to pour the contents. In a foundry, liftout tongs ! Noel

Not strong enough for nut crackers.

Noel, you could pick up a1” diameter crucible but you would pour the metal very close to your fingers??

The cutting tool looks like its for spot facing the back of a hole. For example where you have a pocket in the side of a casting to fit a nut and it need facing square to the drilled hole.

[Bo’sunParticipant @bosun58570]

“Lift-out” tongs for the jewellery, laboratory, or similar trade maybe, but almost certainly not designed for ergonomic/safe pouring.

I think the first item is for removing the ring ridge on a bore

[Phil PParticipant @philp]

Looks like the reamer device operates on a taper shank, so as downward pressure is applied the cutting edges grow in diameter.
No idea what it’s actual use is though.
