So, I guess my question is this. Can I run this same insert in a right
hand, left hand, and boring holder and expect similar results?
Obviously insert tools set up for them at the proper angle. Not just
any old insert tool.


Since no one else has replied............... I think you can use the same insert on both right and left holders. And in a boring bar, but would not expect the boring bar to be as stiff. Carbide comes in different grades. Some are harder, some less likely to chip. So what you have may not be the best for a job, but I think it can be used.

Now for something completely diffecent. Can anyone explain why they use the shape they use. I have a couple of holders that use triangle inserts. Why would I want a different shape? Why is as 86 degree so popular? Why is a Square not as popular? Where is there information on choosing an insert shape.
CarbideDepot.com has a pretty good chart on insert designations, but not on choosing an insert shape.
