I plan to run a part from one side as opposed to flipping it around. I need to back bore and thread.
Kenna has a back boring bar that will work, but it is a 55* insert, and I would really like a 35* insert so that I can leave the 45* thread relief that they call for, but in all honesty, it is a thread relief, so I doubt that it will be the end of the world as we know it if it ends up a 35* chamfer, but still, would be nice to have a 35* insert.
Also, I would like to have a 1.250 bar, and the biggest Kenna goes on this is 1".
Then I need to thread this bore. I could get away with a std bar with a std 60* insert, but I REALLY would like to have cresting abilities if at all possible. So - that means that I want to be able to use a RH insert on a RH boring bar. Or to say another way - on a TOP NOTCH the clamp would need to be further out on the end of the bar, not closer to the turret.
Or more likely - maybe someone might make a lay-down style holder that just has the pocket milled into it the other way.
Can anyone think of such tools off the shelf?
My hole may be big enough that I might be able to make a slotted end shank and clamp in a small external holder. But would like to explore any possible OEM holders.
