I was looking for a new cut off tool because the inserts on the one I am using are breaking.
On another forum I found this little hint that may help others with the same problem, I am pretty sure it is the reason for my problem.
"Important.
When using carbide DO NOT use intermittent cooling (dabbing on with a brush or a squeezy bottle ) as the heat/cool stress shatters the tip surface, run dry or flood."
I am cutting 1.125 1045 TGP bar that has a 3/8 hole through it.
I am using the Hertel MGTN-2-HT25 inserts.
Looking on ebay I see quite a few different ones. GTL 3 HT25, GTR 4 HT25, MGTR-2-8D HT10 etc...
Which ones will fit the tool holder I have that uses the MGTN-2-HT25 ?
Ebal search returns 23 listings search for "hertel insert cut off"
What width cutoff tool should I be using given the stock and size i am cutting.
SB-9 lathe - Belt drive - looking at getting a gator rubber belt drive as i still have slipping on heavy cuts.
