Shank Drill Bits ......i Think!

Gidday Everyone from Australia

First post and apologise for any technical mistakes.

I have inherited some 'shank drill bits' that seem to be of industrial size. I have uploaded some photograghs. Can you please tell me what they are actually called and used for. Any other information would be greatly appreciated. I am uncertain what to do with them. Are they still useful or collectable?

I appreciate your responses and information.

Kindest regards

Stuart

Posibly CNC router bits ...?

They have a strong resemblance to these:

OR if the ends are internally threaded, and are tapered, they would be milling machine cove bits. All the shanks are the same size, but the diameters vary.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Morse taper reams for finishing a drilled/bored hole. They cut only a minuscule amount. NOT drills.

to me I'm thinking router bit of some sort. At the very least though they're cool looking.

Definitely NOT drills.

Not a hand reamer, but used in a milling machine, probably R8 taper with a draw bar to secure them.

I would be interested in the previous owner's background and whether he had a machine shop...?
