A Special Lathe Tool Bit

[carrdo]

Hi All,

Here is a special lathe tool bit which I have used many times to get one into and out of a tight spot/corner where no other tool bit will do the job.

And if one takes light cuts, it will also leave a beautiful surface finish. This one happens to be ground from a standard brazed carbide tool bit but the same can be made from HSS. It just takes a lot of grinding to produce the slim form.

I have often used a parting tool to do the same thing for the same purpose. It's a lot easier to grind........

I did exactly this using a 1mm high speed steel parting blade to make a threading tool to cut 11.75mm x 1.25mm buttress thread. now I only need to get lathe finished and figure out how to set pitch to 1.25mm

You sure like to plan ahead don't you!

Can I assume you have a 127 tooth gear on your lathe? Or is that part of the project?

I missed your reply at the time...

I've been told that my lathe can thread 1.25 metric threads but until I get it spinning I can't actually test that claim. Then there is our other lathe which also should turn this thread too.

I hope to get to get to this in september or october because I really need an adapter to fit W12 spindle
