Al, I think it must have been spinning around 3000 to 5000 RPM. That yellowish color on the rim of the blade could maybe indicate titanium instead of brass. Or maybe bronze.

As an aside....

Hands up who knows what a 'Thread Restoring File" is? (No fair Googling!)

Hi Len,


I'll take a guess: a triangle shaped cross section file? Just a guess though.

Hi again,

I did a little more cutting with a small diamond wheel and it seemed to cut pretty well into
some slightly hardish tool steel. It didnt seem to bother the wheel, but what i did was
i took 'little cuts' by pushing the wheel into the workpiece and then backing out, then
pushing again, then backing out again, etc., to help keep the wheel cool.
I have to say it cut really nice, and i was able to grind a new tip on the tool. It
was a phillips head driver bit that had been worn very very badly so that the first
1/8 inch of the tip had to be cut or ground off and a new tip formed.
I was able to use some diamond files to finish up the new tip.

This was more of an experiment than anything else, but gee now i have a new
phillips screw driver bit :smile:
