OSCARBIDE1/2"Round Shank Boring Bar Set,90 Degree with Indexable Carbide Inserts TCMT21.51(TCMT110204),4 Pieces/Set

only used the smallest one so far but no issues

The quality looks good (fit and finish). I would have given them 5 stars but I haven’t had a chance to use them yet. I will see over time if the inserts are readily available.Vendor shipped quickly!

So far so good. I use these mainly on a hardinge lathe as well as a 1998 HAAS lathe. They work quite well through plastics, aluminum, and mild steels.

High quality tools for small money. Shipping went very well, arrived within 24h in nicely packed box. I definitely recommend the set for any type of aluminum and soft steel projects

Boring bars work great. Each bar came with its own insert and the triangular inserts have a total of 3 usable edges. Really good value

Good set and arrived quickly.

Great boring tools

Boring bars are of the highest quality and work excellent for boring holes.
