Well that's a bit of a blowI'm not a big fan of negative inserts although they do have some advantages double sided, good for taking heavy cuts less prone to break.
However if you want to get a good finish I think positive inserts are the best. They also require less power for the cutting and less force on the workpiece.
So I think you may have to purchase a holder that is suitable for positive insert.
Just my 2 cents
Just as a thought do you have any boring bars?

Do U have any specific holder in mind ??? Let me know as I am presently negotiating getting some down as well.
Bought a cheap set of Boring Bars from "Flea Bay" - like they say, and these came with their own Carbide Inserts as well. Nothing too exclusive, and we knew not better at that time. Also have a mini Mitsubishi with Inserts which is not practical for my 20.20 QCTP Holder. Finally, and a large brazed Carbide one, also to fit the 20.20 holder, but which we only recently realised, requires the QCTP to be shimmed some +6mm to get it on exact Centre to the spindle Bore.
And the reason for asking Dave ??
