Mystery cut-off tool holder
#13
Thanks Ken. These inserts appear to be about 2.2mm wide. On the first attempt I was feeding by hand but keeping steady pressure on the cut, and the chips were flying off of the insert (and breaking) beautifully. So I was expecting the very same thing on the next cut, but...... nothing. 17428

As nicely as it was cutting on the first pass I'm sure I had to be doing something wrong to ruin the insert. 9/16" deep well socket (7/8" OD), 525 rpm, brushed on cutting fluid. The funny thing is I had removed the chrome plating first with a brazed RH tool bit on the lathe and it cut like butter. Chin

That's when I took it over to the mill to cut some flats on the OD, and a good sharp 9/16" HSS end mill self destructed after traveling about 1/4" on a .010" depth cut. Bash

Some days you're the dog... some days you're the fire hydrant.

When I get some more inserts I'll have to put on my big boy pants and try engaging the power feed next time. And pray. Big Grin

Edit to add:
It just occurred to me.... Smiley-signs140
I'm guessing it might have been caused by the interrupted cut?
(OD of the socket was milled into a hex.)
