It's not the only boring bar I have but it's the only one I'm willing to cut to length for the job.

I don't think I've ever used the 45deg end on one of those bars, guess its to get the cutter to a shoulder. The 90 deg hole makes grinding easier for me, don't have to take the tool's angle into account. Do you not have a set of the carbide tipped boring bars, (come on) , I use them pretty much exclusively in the burring head. Cheap and cheerful Chinese but seam to hold up reasonably well.
Free advice is worth exactly what you payed for it.

I have a set but none that are even close to being long enough to bore 3.25" deep.

I'd have to check my set, thought some were at least that long. HUM

My longest Chinese, carbide tipped boring bar is 4.5" from it's 3/4 Dia. shank.

But Ed, can't you slide your boring bar into your QC holder to the length you need? 17428

Steve,

It's set up in the mill not the lathe. My boring head takes 1/2" shank tools and I haven't seen any of the carbide tipped Chinese boring tools with 1/2" shanks that will bore that deep.

Rather than cut up your boring bar(s), maybe mill a pocket on the side of a piece of round stock and attach a carbide insert? You could make it any length and diameter you want. Just trying to think of other options you have on hand....
