Thread: Guess what?

A double sided chamfering tool?

Diamond cluster?

Steel??????

What size is the square of the shank? I'd go with Stu, and think its a chamfering tool off a disc brake lathe. I ask about the shank size as most of then were small, I've never seen one more than 16mm.

The tool is 16mm square, the bits are 3/16". If you look closely you'll notice the trailing tool's point angle is more acute than the leading tool's point angle.

The trailing tool looks to be ground for thread cutting. My guess is that this tool is to turn to a diameter and cut a thread without a tool change?

If that was to be the case, you do know that the feed rate would have to be the same as the pitch per turn?

It's a double sided static steam gurgitatometer.

Steamwisperer will verify this.........

What sort of angle are the HSS bits on. In the first picture they look to be almost vertical. The trailing one has been ground to a sharper angle as has been mentioned.

It looks home made. Maybe it is just a left and right hand tool in one. Only uses one cutter at a time.

Confirmed Ken, gees I thought it was obvious
I'm guessing screwcutting but...

Phil

its a left and right turning tool just waiting to be cut in half straight down the middle.

So does the OP not know what the tool is?

Or is string us along playing a game?

About the only thing I could see it being useful for like that is roughing and finishing in a single pass... First toolbit takes it down roughly to size, rear one looks to have a sharper tip to shave down to final size... One of the operations is always going to be running at less than ideal speeds in that case though...

It's obvious when you look closely at the pictures...

It's a pencil thickness measuring gauge.. you adjust the height of one side until it sits level, then the difference in height is the thickness of the pencil.
