I have some Kennemetal Acme inserts Top-Notch, you can buy them in 5 packs,
I think they are either 4 or 5 TPI. But I already had the holders for them 3
gauge IC for Top-notch/Top-Lok and have the clamp for both the Kennametal
and Sandvik geometries.

I also only ever used one of them and it is still good.

Yep, kennametal is a good quality product, it’s the insert of choice for most of us doing lineboring too.

The boring bar I bought this spring is also from them, pricey but worth it IMO.
