parts of a tool?

[bigdaddie47]

I found these in a bottle when I was cleaning up and resorting my workbench. Not sure where they came from. the Outlined Square one has "ADAMAS THERMILL" on the back. I checked google and found lots of trademark sites and reference to carbide machining but they were all about legal stuff. They are iron with a finish on them. Useful? or fishing sinkers? Thanks to all the gentlemen who have helped me before.

Those cutting bits for metal working machines.   I have used a brake drum lathe that uses the triangle type for surfacing the drums.   

Those can be quite costly new.

Replaceable carbide tips for lathe tools - each shape would have its own holder, to which the tip is held by a high tensile screw..

Most of them are titanium coated indexable milling cutter inserts. I used these for many years on Hurco CNC machines and Bridgeport mills. I still have many of the cutters which use from 1 to 6 inserts. Very expensive.

Defiantly not fishing sinkers.

Not only for metal turning.    If your a wood turner there is a new application.

It is not exactly shear turning, more like shear scraping.    I have tested these tools and they are super easy to use and you get a pretty good finish.

Thank you, Great purveyors of wisdom. Finally something of value in all of my junk. Still haven't found out what my old pump was (canalboat pump was a bust). Now to figure out what to do with them.

Google up carbide recyclers.

About 3 days after you send them off you'll begin to find things you wish you kept them for.

Aunt Phil, I get in enough trouble with my hand tools much less using big guy machines!!  LOL

I bought a brake lathe on Craigslist a while ago.The tool bar takes a funky diamond shaped bit that cost $60.00 each. I just had a friend make me another bat to take the triangle bits that are only $30.00 for 6.

The white diamond-shaped one near the upper right looks to be ceramic. Harder than carbide, but much more brittle.


You can scratch glass with any of those bigdaddie, should you ever get a hankerin' to.
