Can you ID these two tools?

[Bricago]

A CL ad is offering these two tools to whomever can ID them (don't know how they'll know if you're right or wrong, since they don't know either...) I'm really curious about the top one, though.

Any help would be appreciated. Thank you.

It almost looks like some sort of go no go gauge?

 

[Rookie2]

top is a go-nogo depth gauge probably for some type of inspector.

 

[larry_g]

The bottom is a counterbore tool .

Not sure about the top, but the bottom piece is a counter-bore cutter.

bottom looks like some sort of specialty ream, for something that needs aligned and reamed to final size. bought some similar to that and looked up the part #'s, turned out to be for an old Harley, cam bushing ream or something like that.

My first thought too, but it would make no sense for it to have a flared end on the green pin, so possibly not.

The colouring would indicate our first thoughts, but I see what you mean about the flattened tip!

 

[HammerMechanic]

The bottom is definitely a Counter Boring tool. The top looks like some type of a go/no go depth gauge. The flattened tip would be so the rod can not go through the top of the handle. I would think you may push it down in a hole and see which groove the spring clip stops in to tell if the depth is proper.

Some type of depth gauge (certain tread depth gauges also use a flattened tip), looks like it clicks through on the LHS, if you knew graduations one could probably figure out what it was used for.

and a

Piloted counterboring tool.

Tire tread depth gauge for truck tires, green is good with its scale and red is bad with a finer scale to determine how bad. Maybe for weigh station inspections or for fleet mechanic's use.

A slight WAG on my part but l have seen these in a fleet mechanic's box before.

 

[Techie1961]

I agree with the tire gauge Go/NoGo. The bottom though is a spot facing tool I think. I don't think it's a counterbore.

I don't have a better guess, but those tires must have some pretty deep tread!

Good point!

Off road heavy equipment or tractor tire tread gauge??

I think the bottom is a spot facing tool as well. No clue on the top one.

Spotface and counterbore tools are basically the same thing.

The bottom is a gear drive shaft. The attached image is from a rotary hammer drill.

Your not a machinist are you?

Ummm, no! Spot faces are larger in diameter. Counter bores are to accommodate socket head cap screws while spot faces are for creating a smooth surface on typically a casting. They have to provide the larger diameter for a hex head and possibly a washer.

I said "BASICALLY the same thing". I get they can be different sizes/larger difference from pilot to cutter size, but in general they are the same tooling design. There is no way from a crappy picture with no detail measurements whatsoever someone can tell between a counterbore and spotface, unless of course the pilot was significantly smaller(which this is not), then it would most certainly be a spotface.

No not at all. I repaired my Bosch DBH2-26 hammer drill a couple of months ago.

I didn't mean to offend. I don't know if you are a layman or not and I want to add to the knowledge here. As a tool and die maker, they look very different to me and serve a very different purpose. If you have looked at the cutters for many years, it is easy to see that the diameter of the cutter is way too big to be a standard counterbore.

A counterbore has a much smaller ratio of pilot to cutter and is used to hide a screw at the surface level.

A spot face is used to provide a level surface for attachment screws and has a much larger pilot to cutter ratio.

It's kind of like calling a masonry bit a twist drill. They look similar but and do a similar thing but are very different.

I think the Top one is a terminal multi plug insert / removal tool , commonly used in aviation, each plug manufacturer has their own type but generally green for insert ,red for removal
