I have run one like that and a larger 5 incert in my Millport with great
results. I would think a Bridgeport in good condition would have the same
results.

You're going to use this on a minimill? Which minimill is that?
Are we talking 150 Lb Chinese minimill or 850 Lb? It makes a difference.

FWIW, I bought one of these (R8 TP insert holder) for my old Bridgeport 1J
head machine. The machine wouldn't take it. I guess its for sale if
someone wants one.

On my Excello (WAY more rigid) I find the high performance inserts are
worth the extra bucks. You wouldn't believe how fast you can remove metal
with a Sandvick R-390 insert. Same deal with my 10EE, the CNMG inserts
with the LF chipbreaker remove way more metal and give more accurate
results. By that, I mean the TPG seems to cause more deflection pressure
and gives not as repeatable results. Of course, both these inserts are 5X
more expensive. You gets what you pays for.
